How to use the Best 3

Why these metrics matter
Evidence type
Separate OTC drug evidence, anti-dandruff scalp evidence, and cosmetic product-specific studies.
Hair-loss pattern
Sudden, patchy, postpartum, painful, or scarring hair loss needs evaluation before product choice.
Use format
Foam, solution, rinse-off shampoo, and leave-in serum have different routines and tolerability.
Safety context
Scalp irritation, pregnancy, heart or blood pressure context, medication use, and flammability can matter.
