Topical androgen receptor antagonists may not be necessary if 5-AR inhibitors like finasteride or dutasteride effectively reduce DHT levels. Combining a 5-AR inhibitor with a topical androgen antagonist could potentially enhance treatment, but oral use of androgen antagonists is too risky due to severe side effects.
Pyrilutamide is a selective ARantagonist with a high binding affinity, making it effective in competing with DHT for androgen receptors. The 1% concentration is more effective than the 0.5%, but the latter may suffice for mild hair loss; the drug is considered a good option for those avoiding 5AR blockers due to side effects.
Clascoterone in Winlevi, a topical ARantagonist, is being re-examined due to concerns about HPA axis suppression in adolescents, but it's unlikely to be banned for adult use in androgenetic alopecia (AGA). The European Medicines Agency recommended refusing Winlevi for acne vulgaris, but this may not affect Breezula's approval for AGA.
The conversation discusses sourcing pyrilutamide from China for hair loss treatment, highlighting its potency compared to other ARantagonists like bicalutamide and RU58841. The user expresses interest in trying pyrilutamide despite mixed results in clinical trials.
The post discusses using 2% ketoconazole shampoo as a competitive androgen receptor antagonist for hair loss, applied for 1.5 hours daily. The user questions its effectiveness and potential benefits compared to finasteride and minoxidil.
