The Guru Index verdict

The gurus who reviewed it call it a strong value pick. Both dermatologists note the 5% concentration works as effectively as name-brand minoxidil at a fraction of the cost, and Dr. Dray points out that the 5% is often more effective for women than the standard 2% formulas marketed to them. Those with a Costco membership get the best deal, they say, making it their first-line recommendation for anyone starting minoxidil treatment.
