Hi, great article. I have an aggressive form of MPB. I am 23 year old with a NW2 hairline, diffuse thinning over the top and crown. Been on 5% Minoxidil and 2% Keto for about 9 months. Went through a period of shedding which has reduced somewhat in the last couple of months. I don’t see any appreciable increase in density anywhere but I do see plenty of thin vellus hair at my hairline. I am waiting for the 1 year mark to see the full effect of this regime. Is there like a test you can do to assess hairfall? Or do we just have to count the hair lost in the shower? Do you reckon I should start the Fin to hold on the the hair I have? Like most guys (actually a bit more than most guys seeing that I am young) I worry a lot about being in the 2% who experience disastrous sides from Fin. I do plan to check my DHT levels before I start, if I do at all, to see if I naturally have high/low DHT. That should tell me what to expect, to an extent.
There are many potential causes of hair loss, including medical conditions, medications, and physical or emotional stress. If you notice unusual hair loss of any kind, it's important to see your primary care provider or a dermatologist, to determine the cause and appropriate treatment. You may also want to ask your clinician for a referral to a therapist or support group to address emotional difficulties. Hair loss can be frustrating, but recent years have seen an increase in resources for coping with the problem.
These anti-androgenic effects can be used to help treat hair loss. Nizoral shampoo contains 2% ketoconazole and is prescribed not only for the treatment of scalp conditions, but also in combination with other treatments for androgenetic alopecia. A 1% version is now available over-the-counter, but it may not be as effective as the 2% prescription strength. There are no significant side effects.
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."
