Hair and scalp care works best when it is steady — not rushed.

Build the habit. Get used to the serum step and routine rhythm.

Week 3–4
The routine starts feeling easier to keep. Your hair care may feel clearer, lighter, and less overwhelming.
3
Day 60–90
A better time to evaluate how your hair looks and feels with real consistency behind it.
Individual results and experience may vary. HERLAYRA is cosmetic hair and scalp care — not a drug or medical product.
AVOID THESE
Common mistakes to avoid
Small mistakes can make a simple routine feel harder than it is.
Using too much serum
Apply directly to the scalp. Start light. More is not always better.
Only using it on wash days
ActivGrow™ is designed as your daily scalp-care step, including non-wash days.
Rinsing it out
Do not rinse after applying ActivGrow™. Massage gently and leave it in.
Giving up too early
This is a consistency routine, not an overnight fix.
Applying mainly to lengths
Focus on the scalp, not just the hair.
Skipping the massage
A short 10–15 second massage helps make the routine easy to remember.
