What Hair Growth Serums Do
Serums are lightweight liquids applied to the scalp or hair to deliver concentrated ingredients. Many contain minoxidil, peptides, or plant extracts aimed at supporting follicle health. Results vary by formulation and individual response.
Key Ingredients to Look For
Minoxidil is an FDA-approved ingredient for hair regrowth in some cases. Caffeine, biotin, and saw palmetto are commonly included to support scalp circulation or hormone balance. Check labels for evidence-based actives rather than marketing claims.
How to Use a Hair Growth Serum
Apply a small amount to clean, damp scalp, focusing on thinning areas. Consistency matters, with most products requiring daily use for several months. Avoid overlapping products that may irritate the scalp or reduce absorption.
Choosing the Right Product
Consider scalp sensitivity, hair type, and existing hair loss causes when selecting a serum. Dermatologists can help identify underlying issues and recommend suitable options.
