A leave-on scalp treatment built around the same copper peptide system as the rest of the [FORM] lineup, dosed at 5% GHK-Cu and paired with Copper Tripeptide-3. Where the shampoo works in a short rinse-off window, the serum stays on the scalp.

Niacinamide, caffeine, and salicylic acid round out the formula—niacinamide for the look of a balanced scalp, caffeine to energize, and salicylic acid to help keep the follicle area clear of buildup between washes.

A 30ml dropper format for targeted application: two to three drops on the areas you want to treat, massaged in and left to absorb. Built to sit alongside Copper Growth Shampoo, not replace it.

Clinically minded ingredients

A leave-on scalp serum with 5% GHK-Cu, Copper Tripeptide-3, niacinamide, caffeine, and salicylic acid.

5% GHK-Cu

5% GHK-Cu

Why we chose it: Copper tripeptide-1 at 5%, the same core peptide that runs through the [FORM] lineup — here in a leave-on format that stays on the scalp instead of rinsing away.

Copper Tripeptide-3

Copper Tripeptide-3

Why we chose it: The companion copper peptide reserved for scalp care, included alongside GHK-Cu so the serum stays scalp-first rather than a general-purpose hair product.

Caffeine + Salicylic Acid

Caffeine + Salicylic Acid

Why we chose it: Caffeine is included to energize the look of the scalp. Salicylic acid helps keep the follicle area clear of buildup between washes.
