Fact of the day!- Androgenic alopecia, this is a form of hair loss in which develops when the hair follicles within our skin reduce in size as well as a time reduction in the hair growth phase. Androgenic alopecia fortunately for us does not develop in all of the hair follicles at one point, this is the reason some parts of the scalp shed more hair than other areas. There are two types of androgen in which must be considered- Testosterone and DHT (dihydrotestosterone). An enzyme called ‘5-alpha-reductase’ converts testosterone to ‘DHT’ Once DHT is formed this chemical has the ability to bind to any androgen receptor within the hair follicles.Binding reduces follicle activity due to this it shrinks the hair follicle which in turn slows the hair growth cycle, reduces the diameter of the hair shaft meaning over time the hair growth ceases. What causes androgenic alopecia? As boys grow up, their hair follicles are exposed to androgen this is the hormone that decides the appearance and development of masculine/male characteristics that their body has synthesized. Once the hair follicles are exposed to androgen, they become ‘androgen sensitive’, androgenic alopecia can then develop at any point latter in time. Stopping hair follicles from coming into contact with androgens can prohibit the chance’s of androgenic alopecia developing. In females, the mechanism of the condition is very similar to that of a males. the source of the androgen is simply the combined activity of the ovaries/ adrenal glands. Hair loss in women can also be related to pregnancy/ menopause and the effects they have on our bodies.
