Yes. Doctors use the Savin scale. It ranges from normal hair density to a bald crown, which is rare. The scale helps document female pattern baldness, a condition your doctor might call androgenic alopecia. You probably know it as male pattern baldness, but it affects about 30 million American women. Experts think genes and aging play a role, along with the hormonal changes of menopause. Your hair could thin all over, with the greatest loss along the center of the scalp.

Finasteride is taken once daily in pill form. It works by preventing testosterone from being converted into DHT in the oil glands, hair follicles, and prostate. DHT is the form of testosterone responsible for hair loss. There can be some side effects with this medication and your doctor will be able to explain those in greater detail during your consultation.
Hair loss can start as soon as puberty ends, depending on your hereditary sensitivity to DHT. That phrasing is key: Bauman stresses that it is not DHT production that causes hair loss, it's the inherited sensitivity to DHT that causes the loss. Those with high sensitivity will be the first to experience a weakening in their follicles. This results in thinning around the crown and hairline, and lighter pigment in the hair. Behaviors that increase DHT production will magnify the loss depending on sensitivity. These behaviors include smoking, creatine supplements, resistance and weight training exercise, stress, and taking anabolic steroids or testosterone hormone replacement.
A key aspect of hair loss with age is the aging of the hair follicle.[43] Ordinarily, hair follicle renewal is maintained by the stem cells associated with each follicle. Aging of the hair follicle appears to be primed by a sustained cellular response to the DNA damage that accumulates in renewing stem cells during aging.[44] This damage response involves the proteolysis of type XVII collagen by neutrophil elastase in response to the DNA damage in the hair follicle stem cells. Proteolysis of collagen leads to elimination of the damaged cells and then to terminal hair follicle miniaturization.

Is this a bigger issue for the current generation? (I'm 27, and it feels like so many of my friends suffer from this.) Is it a nutritional thing? That’s an excellent question and I don’t know the answer. 30 million women suffer from hair loss. That’s 1 in 4 before age 50 and 2 in 4 after age 50. We might be more hyper aware of hair loss at an earlier age now just as we are more hyper aware of a need for a facelift at earlier ages. Thing that we used to take for granted, we do not. Genetic hair loss will manifest itself in the 20s, if not sooner. The good news is that there are more things available to help than before. Will they work for everyone, no. However, topical minoxidil (Rogaine) is good for helping maintain what you have. So at the first sign of thinning hair, it’s not bad to use even if the hair loss is temporary. 

If you find yourself snacking at night before bed, it may be because you're bored or anxious — not truly hungry — and eating makes you feel better. Try eating a healthy dinner a bit later in the evening. If your stomach is truly growling before bed, try a protein-based snack like a hard-boiled egg or a slice of cheese. A few spoonfuls of yogurt or some fruit is another good option. 
Hi there – I just wanted to submit a comment because I dealt with hair loss as a 25 year old. I am 26 now and my hair is back to its normal thickness. I went through a stressful period in my life when I was not getting enough sleep, not eating enough healthy foods and generally just not taking care of myself. I was suffering from a lot of anxious feelings and depression.
Before you venture into the confusing world of Internet hair loss advice, you should first pay a visit to a hair loss specialist. The doctor will sit down with you and discuss your family and medical history, then take a look at your hair loss and make a recommendation. The doctor might recommend one of the following treatment options for young males who are experiencing hair loss:

Harmful lifestyle plus sure kinds of medications otherwise diseases can lead to hormonal imbalance in men. This inequity might trigger extreme secretion of DHT hormone. Consequently hair begins to fall off in droves. Superior testosterone is linked to hair loss. If you have genetic hair loss, what you inherit is hair follicles which enclose a senior sensitivity to DHT that is a hormone collected of single kind of testosterone.

Some hair loss is associated with stress although male pattern baldness is a genetic condition found in many men. If you find your hair is falling out in clumps or at unpredictable times, it is most likely to be the symptom of something else. This could be stress related but is unlikely to be caused by sexual frustration. The best thing to do is to see your GP for a check up.
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.

Sleep helps all our bodily functions and alow the body to build, repair and restore order. Have a calming bed-time routine such as a lavender bath, avoid stress and technology before bed and try to sleep in a darkened room if possible. Healthy sleep will help to rebalance hormones and nourish the adrenal glands which are the glands that produce stres hormones like cortisol.
However, both men and women are able to use the MHRA licensed and FDA-approved minoxidil – a dose-dependent drug which is applied topically to the scalp where needed to promote hair growth. Various formulations of high strength minoxidil are available for men and women and can form part of a targeted treatment course aimed at stopping shedding and encouraging regrowth.
