Fusco says that there’s something called miniaturization happening at the follicular level when a hair falls out. “Miniaturization refers to the slow shrinking of the hair follicle and the diminution of the hair within, until eventually the follicle no longer exists,” she says. “The remaining tiny hair falls out and nothing grows back.” She says that this is often genetic and caused by a hormone called dihydrotestosterone (DHT), which is a byproduct of testosterone. DHT clings to the follicle and then slowly shrinks it. This most commonly happens at the temples, the crown, and the front of the head. (This is also why you don’t see guys losing their hair around the sides and back.)
Finasteride (Propecia) is used in male-pattern hair loss in a pill form, taken 1 milligram per day. It is not indicated for women and is not recommended in pregnant women. Treatment is effective starting within 6 weeks of treatment. Finasteride causes an increase in hair retention, the weight of hair, and some increase in regrowth. Side effects in about 2% of males, include decreased sex drive, erectile dysfunction, and ejaculatory dysfunction. Treatment should be continued as long as positive results occur. Once treatment is stopped, hair loss resumes.
True. Hair loss can be hereditary. Hereditary hair loss is called androgenetic alopecia, or for males, male pattern baldness, and for females, female pattern baldness. Androgenetic alopecia occurs when a hair follicle sheds, and the hair that replaces it is thinner and finer than what was there previously. The hair follicles continue to shrink and eventually hair stops growing altogether. However, contrary to popular belief, hereditary hair loss is not only inherited from the maternal side – it can be passed down from either the mother’s or father’s genes – but is more likely to occur if both parents have this issue.

Turns out I may be on to something. Research shows that if scalp massages are done with essential oils, including lavender, cedarwood, thyme, and rosemary (the latter being especially effective), they do indeed stimulate hair growth. Of course, the nice thing is, we don’t need to embarrass ourselves by making crazy requests to fancy hair salons (although, if the salon is fancy enough, of course, no request will be seen as crazy); we can give scalp massages to ourselves. And if your sleeping partner doesn’t care, or if you sleep by yourself, then for an additional benefit, you can do what I sometimes do, which is rub rosemary oil with coconut oil into my scalp before bed, and then sleep with it in my hair/head all night.
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.
Calling all gym fanatics—if you’re spending more time in the gym than you’re spending at home, it may be time to reevaluate your regimen. According to a study in the Annals of Dermatology, the more strenuous a participant’s workout routine was, the more likely they were to experience hair loss later in life. If you’re pumping iron more than a few hours a day, it’s going to affect your hairline. So, if you’d like to keep your hair, cutting a few hours of gym time every week may be the trick.
Trich is mostly considered untreatable; there's not enough research into the mental, or neurophysiological mechanisms of action to really underpin the cause. I suspect it works in a similar way to any other addiction; a stimulus like a small amount of pain induces a dopamine response, a pleasurable feeling. After a while, your physiological urge for the dopamine hit overpowers your reasoning to stop.
