The short answer is it depends largely on your genetics. TRT will increase DHT, which is believed to be the main driver of male pattern baldness. (11) Whether a person loses hair with increased DHT typically depends on their scalp’s androgen receptor sensitivities, which is based on an individual's genetics. Luckily, there are ways to mitigate the effects of DHT on the scalp such as finasteride, minoxidil, microneedling and PRP shots. These all allow individuals to take TRT and not worry about hair loss. Another strategy to decrease androgen receptor sensitivity is to take TRT in a daily small dose instead of a once weekly larger dose.
