“You want some sort of strategy to decrease the activity of that androgen receptor. There's a lot of different things that you can do that are topical. The most promising is called dutasteride misotherapy. Essentially, what it is is it's very localized injections in areas that are prone to male pattern baldness. um whether they're a female or a male and it acts locally only and you repeat these injections from time to time. It decreases the conversion of testosterone to DHT just in the scalp.”
