The Culprit
The most common reason for hair loss comes from a chemical called DHT. DHT keeps the follicle in its inactive stage of growth. DHT causes the hair to stop growing and eventually fall out. Hair naturally falls out after six years naturally--but when DHT is present, it doesn't grow back.

DHT, dihydrotestosterone, is testosterone mixed with 5 Alpha Reductase and Androgen, a normal hormone found in the scalp. When DHT is present at the root, it cuts off the blood flow to the follicle and the hair does not regrow, eventually falling out. DHT hair loss is a product of keeping the follicle in the inactive stage of growth.

DHT is present in both men and women, and DHT causes hair loss in both. Although it is more common in men because of their higher levels of testosterone, many women still are afflicted with the hair loss. In women, high levels of DHT can produce thinning hair on their scalp and thicker hair on their face.

DHT Hair loss can be combatted with a DHT blocker, which slows the amount of DHT to the follicle. Less DHT at the root of the hair produces a healthier follicle able to sustain its normal growth pattern. This means that you no longer have to fear DHT-induced hair loss.
