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

  1. Part dry hair and apply a few drops directly to the scalp.
  2. Massage in with fingertips for 1–2 minutes.
  3. Leave in — no need to rinse.
  4. Use nightly. Most people check their results at 8–12 weeks of daily use.
