The viral GHK-Cu peptide, made for your scalp.
A lightweight daily scalp tonic powered by GHK-Cu (Copper Tripeptide-1) — the peptide everyone's talking about — for hair that looks fuller, thicker, and healthier. A few drops a night, massaged in. No rinsing, no greasy residue.
Why you'll love it
- GHK-Cu (Copper Tripeptide-1) — the skincare-favorite copper peptide, now in a daily scalp serum
- Peptide + botanical oils — unlike water-only formulas, castor, avocado & coconut oils nourish the scalp while GHK-Cu gets to work
- Fuller-looking hair — supports stronger, thicker-looking strands from the root
- Lightweight & non-greasy — absorbs fast, won't weigh hair down
- Salon-level peptide care — without the $60+ price tag
How to use
- Part dry hair and apply a few drops directly to the scalp.
- Massage in with fingertips for 1–2 minutes.
- Leave in — no need to rinse.
- Use nightly. Most people check their results at 8–12 weeks of daily use.
