What is DHT?
DHT, which stands for 5α-Dihydrotestosterone, is a male sex hormone and is a derivative of testosterone. Men and Women can lose their hair as a result of changes in the DHT levels. Testosterone is converted to DHT, so higher levels in women can lead to hair loss.
When DHT reaches the hair follicle, it can cause it to shrink which leads to less hair growth and possible hair loss. The more DHT a person produces, the greater the chance that they can suffer from some sort of hair loss. In women, increased levels of DHT can cause their voices to deepen and hair to grow on their chin and chest. Similar to the affects of Polycystic Ovarian Syndrome (PCOS).
Treatment such as Finasteride, can help prevent DHT from reaching the hair follicle, however, it can also cause adverse side effects like depression.
Hormones are cyclical. Testosterone levels in some men drop by 10 percent each decade after thirty. Women’s hormone levels decline as menopause approaches and drop sharply during menopause and beyond. The cyclic nature of both our hair and hormones is one reason hair loss can increase in the short term even when you are experiencing a long-term slowdown of hair loss (and a long-term increase in hair growth) while on a treatment that controls hair loss. -AHLA
