TLDR Small injections of dutasteride improved hair thickness in men with hair loss without major side effects.
The document reports on a retrospective study involving five male patients with Androgenetic Alopecia (AGA) grades IV to VI who were treated with quarterly micro-injections of 0.05% dutasteride and topical minoxidil. After six months, all patients showed improved hair density without systemic side effects. The study concludes that dutasteride micro-injections could be an effective treatment for AGA, but it acknowledges limitations such as the small sample size and lack of a control group. The results indicate a need for further research to fully evaluate the treatment's efficacy.
