Evidence Summary and Critical Appraisal of Studies on the Effectiveness and Safety of Non-Conventional Treatments for Male Androgenetic Alopecia: A Protocol for a Systematic Review

Finasteride may affect liver function and cortisol levels, potentially linking it to non-alcoholic fatty liver disease (NAFLD). More research is needed to understand this connection fully.

A peptide-based hair loss treatment, PP405, reportedly increased hair density by 62% in 90 days, but these claims are unverified and met with skepticism. Users compared PP405 to Minoxidil and Finasteride, expressing doubts about its effectiveness without more evidence.

Use finasteride or dutasteride with minoxidil for at least a year to improve hair density before considering a hair transplant. A transplant might be needed if medications don't provide sufficient regrowth.
