How genetics and hereditary factors can affect hair growth?

Your genes affect how sensitive your scalp is to a hormone called dihydrotestosterone (DHT), which shortens the growth phase of your hair. Your hair follicles also become smaller in response to DHT and you subsequently produce fewer and finer hairs.

What gene determines hair growth?

Moreover, the activation of the Lhx2 gene in hair follicles has been shown to activate the growth phase and hence the formation of hair. Thus, Lhx2 is a gene that is important for the regulation of hair growth.

Does hereditary cause hair loss?

Hereditary-pattern baldness is the most common cause of hair loss. Hereditary-pattern baldness is not really a disease, but a natural condition caused by some combination of genetics, hormone levels and the aging process. Almost all men and women will notice hair loss or hair thinning as they age.

Does hair stop growing?

Hair does not necessarily stop growing when it reaches a specific length but it does once a certain period of time has passed (the cycle of your hair growth). The growth phase of hair is mostly determined by genetics and can last anywhere between two and six years.

How do you know if hair loss is genetic?

Hereditary-pattern baldness starts with thinning of the hair and often progresses to complete hair loss on parts of the scalp. Hairs on the pillow, in the tub or on the comb are unreliable symptoms of hair loss.

Can baldness be cured?

There’s no cure for male-pattern baldness, but some medications can slow it down. Minoxidil is an FDA-approved, over-the-counter treatment you apply to your scalp. It slows the rate of loss and helps some guys grow new hair. But once you stop using it, hair loss returns.
