If you want shinier locks, use conditioner every time you wash. Bonus: Conditioner cuts down on friction and breakage when you brush your hair later. And did you know that you can use conditioner to wash your hair, sans shampoo? Since shampoo can be very harsh, it's a nice alternative once in awhile. Our experts in the Good Housekeeping Research Institute Beauty Labtried it and found that while conditioner may not do the deep cleaning most shampoos will, it will still leave your hair feeling and looking nice
In males over 60, androgen receptor and aromatase levels were low and comparable in scalp with and without thinning in both frontal and occipital regions. The 5a -reductase type 1 and 2 levels were only slightly higher in males with thinning hair in both frontal and occipital regions, but the differences were not significant. Histologic and hormonal findings suggest that senescent thinning is a diffuse process that is histologically similar to Androgenetic Alopecia, but hormonally different and may not be entirely androgen dependent.

I posted some pictures because I am not sure if I am loosing my hair. I have recently noticed some thining in the front and back but I am not sure if I am really loosing my hair or if it recently has just been looking different. I also notice when I stroke my hand through it a lot of strands are easy to pull out. What can I do? Progaine? Rogaine? I am 22. Thanks! READ MORE
Senescent thinning of the scalp hair, or thinning that occurs after age 60, is poorly understood, and it is unclear whether this is a distinct entity or part of the continuum of androgenetic alopecia (AGA).  In a previous study, young males age 18 to 30 with Androgenetic Alopecia had higher levels of 5a-reductase type 1 and 2, more androgen receptors, and lower levels of cytochrome P-450 aromatase in hair follicles in the frontal region of the scalp than in the occipital region.
Minoxidil (Rogaine, generic versions). This drug was initially introduced as a treatment for high blood pressure, but people who took it noticed that they were growing hair in places where they had lost it. Research studies confirmed that minoxidil applied directly to the scalp could stimulate hair growth. As a result of the studies, the FDA originally approved over-the-counter 2% minoxidil to treat hair loss in women. Since then a 5% solution has also become available when a stronger solution is need for a woman's hair loss.
Extreme hair loss should be discussed with your healthcare practitioner. But in the case of mild to moderate thinning hair, which is usually a result of thyroid imbalance, hormonal imbalance, nutritional deficiencies, or elevated stress hormones, most women can get relief naturally — without having to resort to a new hair cut or experiment with hair thickening creams!

One especially effective supplement has emerged in the last few years, and Fusco calls it “a real game changer.” It’s a multivitamin blend called Nutrafol for Men. (Fusco is not paid to endorse it.) She says they many of her patients have “seen regrowth, thicker hair and a healthier scalp after using it. It’s packed with botanical ingredients that help multiple causes of poor hair health, including hair loss from inflammation, stress, hormone imbalance, genetics, and environmental toxins.”
Guys are indeed losing hair earlier than their fathers. Four trichologists who spoke to the Times of India say while it’s normal to lose 50 to 100 hairs a day, more than that could indicate a health issue. Consider that the body typically sheds hair in response to extreme mental or physical stress, with hair loss that shows up several months after the event.
If you’re beginning to notice more of your hair clogging up the drain, it may be time to do a thorough assessment of the products you’re using on a daily or weekly basis. For starters, as previously mentioned, it might be a good idea to replace your standard shampoo with one that is strictly clarifying. While you’re in the shower, right after you’ve rinsed the conditioner out of your hair, stimulate hair growth by giving your scalp a quick 30-second massage. Finally, forego the stigma of Rogaine to reap the scientifically-proven benefits that are an easy addition to your morning routine.
Hi Will, my hairline has been receding since the age of 17. I’m 21 now and my hairline has receded worse, and I feel so bad at how I look that I barely communicate with people anymore 🙁 I want to know if excessive masturbation could have anything to do with my hairloss, but its supposedly a myth?! Is there any info you can share on this topic, Will?
Anagen effluvium is rapid hair loss resulting from medical treatment, such as chemotherapy. These potent and fast-acting medications kill cancer cells, but they may also shut down hair follicle production in the scalp and other parts of the body. After chemotherapy ends, hair usually grows back on its own. Dermatologists can offer medication to help hair grow back more quickly.
Hi David, I understand where you are coming from. Losing hair at a young age is not a nice experience. Luckily, there is a lot more you could be doing besides the shampoo. Honestly I don’t know how much this will help in the long term. To get you started, you’ll probably have to adjust a few things in your diet and lifestyle to stop further loss/ regrow lost areas. A simple thing to get started would be to use a dermaroller (or even better a dermastamp) along the hairline. Remember though, pattern baldness starts from the inside out. It’s basically a sign that your body is out of balance. So try to sort that out as well.

Daily hair counts are normally done when the pull test is negative. It is done by counting the number of hairs lost. The hair from the first morning combing or during washing should be counted. The hair is collected in a clear plastic bag for 14 days. The strands are recorded. If the hair count is >100/day, it is considered abnormal except after shampooing, where hair counts will be up to 250 and be normal.[citation needed]
Thanks for sharing this..actually i am suffering from this problem last 3 years. After reading your blog I get a solution to rescue from hair fall. I will definitely try it…Parijatak Ayurveda provides plans for a wide range of ailments, thus spreading the magic of this traditional mode of treatment to each one. Parijatak also provides treatment for Tips for hair loss. nowadays hair loss related problem gets more increased, so we have to care about that.
your situation is very common and I assume you have had a thorough investigation ruling out any medical condition for your hair thinning. Minoxidil may restore some vellus hair but unlikely to result in significant terminal hair. As long as it is not getting worse, then a hair transplant procedure may be the answer for you to restore the feminine shape to your hairline 
Research suggests that hair loss during menopause is the result of a hormonal imbalance. Specifically, it’s related to a lowered production of estrogen and progesterone. These hormones help hair grow faster and stay on the head for longer periods of time. When the levels of estrogen and progesterone drop, hair grows more slowly and becomes much thinner. A decrease in these hormones also triggers an increase in the production of androgens, or a group of male hormones. Androgens shrink hair follicles, resulting in hair loss on the head. In some cases, however, these hormones can cause more hair to grow on the face. This is why some menopausal women develop facial “peach fuzz” and small sprouts of hair on the chin.
Senescent thinning was indistinguishable from androgenetic alopecia in older males. Inflammatory changes were not a significant feature. Biochemical analysis for androgen receptors, 5 -reductase type 1 and 2, and aromatase, in scalp biopsies from older males showed nearly a two fold decrease in levels compared to levels in young males with Androgenetic Alopecia.

Research is looking into connections between hair loss and other health issues. While there has been speculation about a connection between early-onset male pattern hair loss and heart disease, a review of articles from 1954 to 1999 found no conclusive connection between baldness and coronary artery disease. The dermatologists who conducted the review suggested further study was needed.[41]
Hi Will. I have a question regarding on my hair loss problem. Currently, I’m still on my 19 but I already have that M-shaped on my hairline which is really absurd and devastating for me. I met a doctor one month ago and he prescribed me with ketoconazole shampoo. The result is quite impressive as my hair didn’t feel itchy anymore. The thing is, the hair on my hairline is still not growing as much as the other parts of my head but the fine hair didn’t fall out. Is it going to be like that or is there anything that I should consider to make it grow back?
The benefit of having a thick head of hair is that the top of your head stays protected from UV rays. But once your hair starts thinning and you begin to lose that protection, you’ll find that your scalp is more susceptible to sunburn. If you’re not spending more time outdoors than usual and your scalp is becoming more sensitive to the sun, you could be losing some of your hair.
Ever feel like pulling your hair out?  Menopause can do that to you.  Hot flashes, weight gain, crankiness—but wait—there’s more!  Just when the mind reels from those menopausal symptoms, one day you notice your hair is not quite as thick and shiny as it used to be.  In fact, there are some tiny patches where you can actually see scalp!  What is going on?
In either sex, hair loss from androgenetic alopecia occurs because of a genetically determined shortening of anagen, a hair's growing phase, and a lengthening of the time between the shedding of a hair and the start of a new anagen phase. (See "Life cycle of a hair.") That means it takes longer for hair to start growing back after it is shed in the course of the normal growth cycle. The hair follicle itself also changes, shrinking and producing a shorter, thinner hair shaft — a process called "follicular miniaturization." As a result, thicker, pigmented, longer-lived "terminal" hairs are replaced by shorter, thinner, non-pigmented hairs called "vellus."

I am in my 20’s and I’m at my stage 2 of male baldness pattern . The M shape on my forehead has increased drastically just over 1 year . I also think about the fact that water might also be a reason for hair loss. I need suggestions about going for a hair transplant because I have used some Ayurvedic shampoos available in the market but got no benefits out of it. And my background is that I am an Indian and currently in a B.tech collage in a hostel where mess food is really very shitty. One more thing I would like to add is that when I was around 12-13 years I used gel just after I shampooed myself which made my hair very rough and I also have curly hair which sums up all my hair problems which I deal daily. Please help

I have been loosing hair for 3 years now. It started at the temples, but actually it falls from anywhere in the scalp. I notice that my hair is pretty thin and weak. I’ve changed my diet in the last month and a half, but it keeps falling almost the same. I have a pretty stressful life, but I’m not sure if that’s the only reason (because on non stressful periods of time, the falling is almost the same). The thing is that I notice that my scalp is almost always itchy, a lot of the hairs that falls, falls with a grease yellow or white bulb at the end. I have to wash my hair almost every day I read that it could be Telogen effluvium, but it has been falling for so long that I don’t think that it’s the reason… It is starting to be noticeable the lack of density, specially in the front. I should be more active as well, but even if I do exercise, I keep feeling that my hair is thin and breaks and falls easily… I would really like to regrow what I’ve lost, but my main focus right now is to stop the hair from falling. Do you think I could have some sort of skin condition that is making this happen? (I have visited 2 dermatologist but both said it was AGA without almost looking at my scalp). Or is this also possible in typical Male pattern baldness?
Finally, while it’s hard, it’s just as important to keep things in perspective with hair loss at 20. Yes, it’s creepy when you first see it, but you’re not alone. Many guys lose hair in their twenties, and a whopping one in every two will have it by 50. So you’ve got hair loss at 20. That’s a good thing. You’ve got a 30 year head start to learn how to rock that look over the guy who loses hair later in life.
Once considered a mark of a middle age crisis among men, hair loss and thinning hair is fairly common among women as well. Some 30 million women in the U.S. have hereditary hair loss (compared with 50 million men). Daily tasks such as brushing and washing your hair can turn from relaxing to puzzling when excess shedding around the hairline occurs. Being an unlucky victim of either genetics or improper hair styling can cause a receding hairline.
The pull test helps to evaluate diffuse scalp hair loss. Gentle traction is exerted on a group of hairs (about 40–60) on three different areas of the scalp. The number of extracted hairs is counted and examined under a microscope. Normally, fewer than three hairs per area should come out with each pull. If more than ten hairs are obtained, the pull test is considered positive.[27]
Hair grows in three different cycles: anagen, catagen, and telogen. About 90% of the hair on the head is in the anagen, or growth phase, which lasts anywhere from two to eight years. The catagen, or transition phase, typically lasts 2-3 weeks, during which the hair follicle shrinks. During the telogen cycle, which lasts around two to four months, the hair rests.

Im a 20 year old male and since i was 18 ive always noticed ive had a slightly receded hairline starting to form. I figured it as normal and a "mature" hairline. However about a month ago one day I woke up, and literally clumps of my hair are falling out now and it is scaring me. I used to loose around 5-10 hairs a day... now im losing about 100 on normal days and 150 on days i wash my hair.... READ MORE


Beginning at perimenopause in their 40s, women may see the effects of menopause on hair, including thinning hair, dull, graying and hair loss. Experts previously thought hair loss due to menopause was caused by low estrogen levels. But new research shows that hair loss in older women is likely due to lower levels of both estrogen and progesterone, causing hair follicles to thin and hair to fall out.
It’s simple, really: the more you mess with your hair, the more damage you cause to your follicles. This truth was laid out in Dove Men+Care’s Hair Fall Study, which found that the over-styling and use of heated tools were incredibly damaging to hair. As it turns out, the solution to this problem is equally simple: don’t overdo it. At the most, you should only need to use heat on your hair once a week. To make your style last longer, it may be time to invest in a can of dry shampoo. And for more hair care tips, This is the Healthiest Way to Straighten Your Hair.

Hair has deep psychological and sexual meaning. Both menopause and loss of hair are often associated with loss of femininity and sexuality. These thoughts and changes can all feed into each other, and it becomes a vicious and demoralising cycle. Rest assured, though, it is very rare for a woman to go bald. And things can be done to get the best out of your hair during this stressful time.
Some things are harder to let go of than others. However, wisdom helps us nurture deeper feelings of self-esteem and a positive spirit. If you find that you are experiencing sudden hair loss, be sure to see your physician. In the meantime, get creative with a new fun style that can make your hair loss less noticeable.  It is not exactly “modern medicine”, but today we have access to hair extensions, clip-ons, scalp camouflages,  and oodles of accessories that can add the appearance of length and fullness without anyone knowing.
In my youth, stylists would always tell me, "Wow, you've got a lot of hair." So much so that I took my lush mane for granted—perming, straightening, and bleaching my way through my teens. But everything changed during my sophomore year of college, as I found myself pulling more and more tangles out of my brush and strands from the shower drain. The compliments stopped and the worry began. I jealously examined the girl next to me on the subway. Why couldn't I see through to the roots on her scalp, too?
I started loosing of my hair at age of 16 only. I was loosing 30–70 hairs. I was worried about it. After my 12th exam I moved to Panipat, there also same thing was happening with my hair(college days). I was 22 when I came to Bangalore in 2015 for job search I realized that loosing 30–70 hair is normal. In two months of struggling period I lost 30% my hair (rate was higher this time). My hairline was receding but It was not noticeable to others. I went back to my home town for 1 months and my hair fall was stopped. I got my posting in Chennai. I was worried because I thought now i will loose more hair. After 5 months I came to bangalore again and I noticed hair fall rate in bangalore is more than chennai. I was very worried, after lot of research I finally thought to consult to dermatologist for PRP treatment. I consulted Dr, parth sarathi (MG road). I read about PRP treatment and it was impressive. Before that i tried livon hair gain also. OK.. Now coming to dermatologist part. He took my 40k (aprx) but nothing happened to my hair. I had gone through 3 PRP session also, applied topical solution of serums (suggested by doc). I lost more hair. Now I have very less hair on scalp. I can see my my bald scalp.

Good hair adds to the personality of a person and its loss deeply affects most of the people suffering from its breakage or thinning, especially those in age group 20s and 30s as you have rightly pointed out. The breakneck pace of today’s world, unhealthy eating habits, illnesses all contribute to hair fall. Thanks for the informative article though..keep up the good work.

Oh my receding hairline is so tied to hormones! I lost my first batch of my thick, beautiful hair when I was pregnant and the next after my hysterectomy….I am still thinning and, you are right, it does seem to worse when I am stressed. It does change how I feel about myself. Thank you for, as usual, bringing great solutions and suggestions Ellen. I will definitely check some out!

Then I hit a wall. I couldn't cover it up anymore. It was obvious to everyone around me that I was trying to hide my hair loss. I had two options: accept the situation or change it. The treatment options didn't work for me, I wasn't about to shell out money for a risky hair transplant surgery and I didn't feel comfortable wearing a toupee. I had to learn to embrace my male pattern baldness or live with constant anxiety and depression.

A new medication can bring about a whole host of changes to your body—while also affecting the rate at which hair grows on your entire body. Certain medications can lead to two types of hair loss: telogen effluvium and anagen effluvium. Telogen effluvium can begin to take effect within the first two to four months after taking a new medication. If you notice more hair loss than usual, notify your doctor immediately to save your most prized possession from further damage. The second type of hair loss, anagen effluvium, is most common in cancer patients receiving regular doses of chemotherapy. This type of hair loss prevents your matrix cells from producing new hair altogether, meaning that you may lose hair on other parts of your body as well. And for more ways to make the most of your mane, check out these 15 Top Hair Tips from Top Hollywood Stylists.


Alopecia areata is an autoimmune disorder also known as "spot baldness" that can result in hair loss ranging from just one location (Alopecia areata monolocularis) to every hair on the entire body (Alopecia areata universalis). Although thought to be caused by hair follicles becoming dormant, what triggers alopecia areata is not known. In most cases the condition corrects itself, but it can also spread to the entire scalp (alopecia totalis) or to the entire body (alopecia universalis).

This is a hereditary condition that affects about 30 million American women, according to the America Academy of Dermatology, and is the most common kind of hair loss Rogers sees in her practice. She tells WebMD that it happens to about 50% of women. Although it mostly occurs in the late 50s or 60s, it can happen at any time, even during teenage years, Rogers says.


People have between 100,000 and 150,000 hairs on their head. The number of strands normally lost in a day varies but on average is 100.[8] In order to maintain a normal volume, hair must be replaced at the same rate at which it is lost. The first signs of hair thinning that people will often notice are more hairs than usual left in the hairbrush after brushing or in the basin after shampooing. Styling can also reveal areas of thinning, such as a wider parting or a thinning crown.[citation needed] 

I am 18 year old male and have been experiencing hairfall since i am 16 years old.More than 60 hairs shed everyday and I have formed a typical m shape.The hair is falling from all over the scalp and become thin from all over the scalp.Also if I don’t shampoo my hair for one or two days, excessive oil comes in my hair.I am also shedding hair from the sideburns.Also my eyebrow,eyelashes and public hair are falling.Is this male pattern baldness.
Hormonal imbalance. Hair loss during menopause and perimenopause is common due to declining estrogen levels. As estrogen levels fall, the resulting imbalance between estrogen and testosterone can cause thinning hair on certain areas of the head that are sensitive to androgens, commonly referred to as male pattern baldness. The same imbalance can also contribute to unwanted hair growth on the chin and face.

Each hair develops from a follicle — a narrow pocket in the skin — and goes through three phases of growth. Anagen (A), the active growth phase, lasts two to seven years. Catagen (), the transition phase, lasts about two weeks. During this phase, the hair shaft moves upward toward the skin's surface, and the dermal papilla (the structure that nourishes cells that give rise to hair) begins to separate from the follicle. Telogen (C), the resting phase, lasts around three months and culminates in the shedding of the hair shaft.

The basic approach is to stimulate hair growth at the root by giving your body the support it needs. Many women find that a nutrient-rich diet, high-quality nutritional supplements and a little stress relief can do wonders. If you find your hair loss is connected to a thyroid, hormonal, or stress imbalance, a specific herbal combination product will help to rebalance your body naturally.
In men, finasteride (originally marketed as Proscar) is approved for hair loss associated with androgens. In one study, 62% of women also taking oral contraceptives containing the synthetic progestin drospirenone reported improvement. So it may be effective for female hair loss in the setting of increased androgen. But studies are limited and it is harmful to the male fetus so should not be used by women thinking about becoming pregnant or who are pregnant.

The patch got larger and I went to the doctor again, who informed me that because I have a family history of auto immune disease (my mother has rheumatoid arthritis) this may have affected my hair loss. Once again, there was nothing to be done except take care of myself and wait for it to grow back. Again, I was so self-conscious of it being seen by other people. It's still growing back now and I have to straighten the curl down.
Consider consulting a nutritionist to see if you might be deficient in certain nutrients that are vital to hormone balance and hair health for example B Vitamins, Zinc, Omega-3 fatty acids. Consider using Viviscal, a natural supplement containing Amino-Mar which is shown to promote hair growth. Viviscal Shampoo and Conditioner can also be used to ensure hair health inside and out.
Any kind of physical trauma—surgery, a car accident, or a severe illness, even the flu—can cause temporary hair loss. This can trigger a type of hair loss called telogen effluvium. Hair has a programmed life cycle: a growth phase, rest phase and shedding phase. “When you have a really stressful event, it can shock the hair cycle, (pushing) more hair into the shedding phase,” explains Marc Glashofer, MD, a dermatologist in New York City. Hair loss often becomes noticeable three-to-six months after the trauma.

Start by getting good sleep, consistently. Cut back on smoking and drinking, both of which compromise the hair’s fiber production. Bauman says to avoid certain medications, like antihypertensives (which prevent high blood pressure complications), hormone treatments (such as thyroid or testosterone hormone replacement), statin drugs, mood modulators (like antidepressants and anti-anxiety agents), all of which that can hinder the hair’s growth and strength. And, as mentioned, avoid supplements like creatine, which will increase DHT production and thus accelerate loss.


There are two types of identification tests for female pattern baldness: the Ludwig Scale and the Savin Scale. Both track the progress of diffused thinning, which typically begins on the crown of the head behind the hairline, and becomes gradually more pronounced. For male pattern baldness, the Hamilton–Norwood scale tracks the progress of a receding hairline and/or a thinning crown, through to a horseshoe-shaped ring of hair around the head and on to total baldness.
Hair grows in three different cycles: anagen, catagen, and telogen. About 90% of the hair on the head is in the anagen, or growth phase, which lasts anywhere from two to eight years. The catagen, or transition phase, typically lasts 2-3 weeks, during which the hair follicle shrinks. During the telogen cycle, which lasts around two to four months, the hair rests.
