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.
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.
