What OTC Hair Growth Products Are
Over-the-counter hair growth products are non-prescription treatments you can buy online or in stores. They usually contain active ingredients that support scalp health, hair thickness, or the growth cycle. Common forms include serums, foams, shampoos, and supplements.
Common Ingredients and How They Work
Minoxidil is an FDA-approved topical ingredient that can help slow hair thinning and support regrowth. Other ingredients include biotin, caffeine, ketoconazole, saw palmetto, and peptides. Biotin supports keratin production, while caffeine and ketoconazole may improve scalp conditions. Always check product labels and talk to a pharmacist if you are unsure.
How to Choose the Right Product
Start by identifying your hair type and thinning pattern. Look for products with clinically studied ingredients and clear usage instructions. Check for third-party testing or references to clinical data, such as information on clinical research. Patch test new products, follow directions, and give treatments several months before evaluating results.
