How to Choose the Best Hair Growth Serums
Look for proven or well-studied actives like minoxidil (the only FDA-approved topical for regrowth), or supportive ingredients like peptides, caffeine, biotin, and rosemary in non-medicated serums. Choose a lightweight, non-greasy formula you’ll apply consistently to the scalp. Results take months and require regular use, so commit to a routine. Pair with gentle scalp care. A good serum is a consistent, scalp-focused step toward thicker-looking hair.
