In understanding hair loss and re-growth, one will encounter the term DHT. DHT is short for Dihydrotestosterone, which is a sex hormone mainly found in men. When the production of androgen in the body is high, this results to hair loss. One of the most common conditions of male baldness is androgenic alopecia that means hair follicles get sensitive to the presence of DHT. And when this happens, the follicles start to shrink, shortening its lifespan and disrupting hair production in the process.

MINIATURIZATION

A vital part of hair follicles is called dermal papilla. When their cells divide, it forms a new batch of hair follicles. Because of this, its presence is important in hair growth. Also, it absorbs the essential nutrients it needs to further improve hair re-growth. However it also has androgen receptors and when DHT gets into it, it weakens the dermal papillas ability to absorb nutrients that hair follicles need to properly function. Because of this, the follicles stay in resting phase longer while the growth stage becomes shorter. Also, hair follicle miniaturization can produce hair that is finer and light-colored which is not a sign of healthy and strong hair.

HAIR LOSS IN MEN AND WOMEN

DHT is mostly associated with male baldness since men have more of these hormones in their body. However, DHT is also present in females, but the amount is not as much as men. This means that men are more likely to lose hair especially as they age. In fact, according to some studies, the effects of DHT in the hair follicles are mainly the reason of most cases of men baldness. However, not all hair follicles are harmed with DHT. Only those with androgen receptors are affected. And in men, these receptors can be found along the temple, hairline and front scalp, which explains hair loss in those areas. However, in females, these hair follicles with androgen receptors are found only on the crown of the head.

HEREDITY

Heredity plays a major role in hair loss because some people have genetic predisposition of pattern baldness. If hair loss runs in the family, then most likely your hair follicles will also miniaturize. This also explains that the mere presence of DHT cannot be considered as the main cause of baldness. It doesnt automatically mean it will damage all hair follicles and everyone will suffer from total hair loss. The shrinking of follicles is caused by ones own genetic formation. If your androgen receptors are normal, then you don’t have to worry about it.
