The hair growth serum aisle has exploded in the last few years, and half of what’s on the shelf is marketing dressed up as science. Clients bring me bottles all the time asking if they’re wasting their money, and honestly, sometimes they are. But a well-formulated serum with the right actives can genuinely support growth when you know what to look for.
Here’s what I actually tell clients before they hand over their card for a serum.
Look for Minoxidil If You Want Clinical-Grade Support
Minoxidil is the only topical ingredient with strong clinical backing for hair growth. If you want proven results, this is the active to prioritize over trendy botanical blends.
Peptide Serums Are the Gentler, Slower Option
Peptide-based serums work more gradually and gently than minoxidil, a good fit for clients who want support without the shedding phase minoxidil can trigger initially.
Apply to a Dry, Clean Scalp for Best Absorption
Serum applied to oily or product-laden hair won’t absorb properly. Apply to a clean, dry scalp so the active ingredients actually reach the follicle.
Commit to Consistent Daily Use
Growth serums require daily, uninterrupted use to see results. Skipping days repeatedly resets progress more than people expect.
Expect a Realistic Timeline of Three to Six Months
No serum shows results in two weeks. Set the expectation at three to six months of consistent use before judging whether it’s working.
Check With a Dermatologist If You’re Pregnant or Nursing
Some active ingredients in growth serums aren’t recommended during pregnancy or nursing. Always check with a doctor before starting one during that time.
