What is Finasteride?

Finasteride 1mg is a low-dose formulation of the competitive 5α-reductase Type II inhibitor — the clinically established dose for androgenetic alopecia research models. At 1mg, scalp and serum DHT are reduced ~60–70%, with minimal impact on total testosterone. Enables hair follicle DHT research, dermal papilla AR sensitivity studies, and dose-comparative 5α-reductase inhibition protocols. Research use only.

Research Applications

Hair Follicle DHT Research

Scalp DHT reduction, dermal papilla AR sensitivity, follicle miniaturisation models

Androgenetic Alopecia

Hair cycle modulation, telogen:anagen ratio, miniaturisation reversal studies

Low-Dose 5α-Reductase Inhibition

1mg vs 5mg dose comparison — scalp vs systemic DHT reduction profiles

Dermal Papilla Biology

DHT-mediated papilla cell apoptosis, AR expression, growth factor signalling

HPG Axis at Low Dose

Minimal T→DHT impact on feedback — LH/FSH response at 1mg finasteride
