Scalp DHTsuppression is more effective than systemic suppression, with 0.5 mg finasteride blocking 85-90% of scalp DHT. The discussion seeks further insights on this topic.
Reducing scalp DHT doesn't directly correlate with preventing hair miniaturization, as different follicles have varying sensitivity levels. Dutasteride at 0.5 mg and 2.5 mg shows minimal visual difference in hair regrowth, with side effects being a consideration for higher doses.
Dutasteride reduces DHT more effectively in hair follicles than finasteride, but some individuals still experience hair loss despite treatment. Combining oral and topical finasteride may improve results, and some users experiment with topical dutasteride despite uncertainties about its absorption.
The conversation discusses the effectiveness of various doses of Dutasteride in reducing scalp DHT and its impact on hair count. Users shared personal experiences with hair loss treatments, including Dutasteride, Finasteride, and Minoxidil, with one reporting significant hair loss reduction using a combination of oral Dutasteride and topical Minoxidil and Finasteride.
Minoxidil may suppress androgen activity in hair follicles, potentially aiding in hair growth and prostate cancer treatment. Users discuss the effectiveness of minoxidil and finasteride for hair maintenance and regrowth, with some preferring topical applications over oral due to safety concerns.

This study found that dutasteride more effectively reduced serum dihydrotestosterone levels than finasteride in patients with benign prostatic hyperplasia.
This study found that Eucommia ulmoides bark extract shows potential antioxidant and hair follicle-support properties in vitro and in vivo, but further validation is needed to confirm these effects.

In this paper, the authors detailed the role of 5-α-reductase in male androgenetic alopecia and discussed potential inhibitors like saw palmetto extracts, suggesting further investigation into their effects on hair follicles and associated biological processes.

Can bicalutamide stop DHT from shrinking your hair follicles?Bicalutamide blocks androgens at the receptor rather than lowering DHT, and some dermatologists prescribe it off-label for women with pattern hair loss. The published evidence is retrospective case series and one small pilot study, with no randomized trial; it is a prescription drug that requires liver monitoring and is contraindicated in pregnancy.
Does metformin help control DHT levels that trigger androgenic alopecia?Metformin has been shown to lower circulating androgens in women with PCOS, but no published study has measured scalp DHT, 5-alpha reductase activity in the follicle, or hair density in anyone taking it — so its effect on pattern hair loss is untested, and it is not a DHT blocker.
