Dihydrotestosterone, or DHT, is a potent androgen derived from testosterone. High DHT levels significantly contribute to androgenetic alopecia (male pattern baldness) in men and women. This happens because DHT binds to receptors in hair follicles, shrinking them and ultimately leading to thinner, weaker hair and eventual hair loss.
The process begins with 5α-reductase enzymes converting testosterone into DHT. Two main types of 5α-reductase exist: type I and type II. Type II is primarily responsible for DHT production in the scalp. This is why targeting this enzyme is a common strategy in hair loss treatments.
Genetic predisposition plays a key role. Individuals genetically predisposed to increased DHT sensitivity experience accelerated miniaturization of hair follicles. This genetic susceptibility means some people are more vulnerable to DHT’s effects than others.
Managing DHT levels is a critical element in combating hair loss. Lifestyle choices, like diet and stress management, influence hormone balance, impacting DHT production. Certain medications can also interfere with DHT production or its effects on hair follicles.
Consult a dermatologist or trichologist for personalized advice. They can assess your individual situation and recommend suitable treatment options, including medications that inhibit 5α-reductase or other approaches tailored to your needs.
