Hair loss is a genetic/hormonal process that can affect both men and women. Hormones that bind to hair follicles can cause an imbalance in the biological processes that cause hair growth. Eventually, excess hormonal action on the follicle causes hair to stop growing and the follicle dies.
Hormones govern the growth of hair. In men, the male hormone, testosterone, governs beard, body hair and hair in the armpits. In women, estrogen, the female hormone generally prevents hair growth on the chin and encourages it to grow on the head. Occasionally, women develop signs of hair loss or baldness when estrogen levels drop.
This patterned form of hair loss is called androgenetic alopecia. This term means hair loss caused by sensitivity to male hormones which exist in both men and women. DHT (Dihydrotestosterone) is one of the main enemies in the war on hair loss in women.
DHT is a potent form of testosterone and acts on hair follicles via androgen receptors. DHT has a disastrous effect on the scalp hair follicles so they begin to shut down and the hair eventually falls out. DHT can also cause the hair follicles to produce sebum. Sebum is a fatty substance secreted from the sebaceous glands most of which open into hair follicles.
