Short answer: ketoconazole is an antifungal that treats dandruff and seborrheic dermatitis, and it's widely used as a supporting part of hair-loss routines. Some studies suggest it may help with pattern hair loss, possibly through anti-inflammatory and local anti-androgen effects. It works best alongside minoxidil and finasteride.

How ketoconazole may help hair

Studies comparing ketoconazole shampoo with minoxidil have found improvements in hair density and shaft diameter, though the evidence base is smaller than for finasteride or minoxidil.

1% vs 2%

1% ketoconazole is available over the counter in the US; 2% is prescription strength. Both are used 2 to 3 times a week.

How to use it

  1. Lather into a wet scalp, not just the hair.
  2. Leave it on for 3 to 5 minutes.
  3. Rinse well.
  4. Use 2 to 4 times a week, or as directed.

Our pick: Regenepure DR

Regenepure DR is a sulfate- and paraben-free shampoo with ketoconazole, built for daily-routine hair-loss use alongside minoxidil or finasteride. Sulfate-free formulas are gentler for frequent washing, which matters if you shower after every workout.
