Dutasteride mesotherapy, involving localized injections in areas prone to male pattern baldness, is a promising topical treatment that acts locally to decrease testosterone to DHT conversion in the scalp, potentially avoiding systemic side effects.

“The most promising is called dutasteride mesotherapy. Essentially what it is is it's very localized injections in areas that are prone to male pattern baldness, whether they're female or 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.”
