Prescription medicines

Several treatments described here — finasteride, dutasteride, spironolactone, oral minoxidil — are prescription-only medicines with documented adverse effects. Finasteride and dutasteride are contraindicated in pregnancy and can cause birth defects. Nothing here should be read as a recommendation to obtain or take any medicine outside the care of a prescriber.

When to seek care promptly

Sudden patchy hair loss, hair loss with scalp pain, scarring, blistering or inflammation, or hair loss alongside other unexplained symptoms should be assessed by a doctor rather than researched online. Some scarring conditions cause permanent loss if untreated, and time matters.
