Articles on hair loss and scalp health, from the biology of androgenetic alopecia to the treatments that actually hold up in the research.
What the Cosmo Pharmaceuticals Scalp 1 (5.39x) and Scalp 2 (1.68x) Phase 3 readouts actually show for clascoterone in male hair loss, and where the topical AR antagonist sits relative to RU58841, pyrilutamide, finasteride, and minoxidil heading into the 2026 approval window.
