Overwashing strips protective lipids while underwashing feeds Malassezia. Find the right hair washing frequency for thinning hair and treatment routines.

Tracking Hair Loss With Darker Skin Tones: Photography and Scoring Tips

Standard hair loss photo guides assume light skin. Here is how to calibrate lighting, exposure, and angles for accurate tracking on Fitzpatrick IV to VI skin.

Clascoterone for Hair Loss: How the Topical Anti-Androgen Works

Clascoterone blocks androgen receptors locally without systemic effects. Here is the mechanism, clinical data, FDA status, and how it compares to finasteride.

Exosome Therapy for Hair Loss: What the Science Actually Shows

Exosome therapy costs $3,000 to $5,000 per session with limited human trial data. Here is an honest look at the mechanism, evidence, and marketing red flags.
