Regrowth+ Peptide Serum is powered by GHK-Cu, the copper peptide skincare labs can't stop talking about. A leave-in step for the scalp, made to sit alongside the shampoo and conditioner you already use.

What is GHK-Cu?
GHK-Cu is a small peptide, three amino acids, bound to a copper ion. Your body already makes it, and it's found naturally in human plasma. Levels drop as we get older.
It's one of the most researched peptides in skincare, studied for its role in supporting the skin around the follicle. We've put it at the centre of a serum made for the scalp.
Three amino acids wrap around one copper ion and hold on tight. That grip is what makes GHK-Cu so useful: it carries copper, a mineral skin needs for its own repair work, in a form skin cells recognise.

The science · 02
Where it goes to work.
Hair starts below the surface. Each strand grows from a follicle sitting in the skin of your scalp, so that skin is where the serum goes.
1Applied to a clean scalp. After the shampoo has cleared the mineral film from the water, drops go straight onto the skin.
2Into the surface layers. GHK-Cu is small: three amino acids, so it's built to work with skin.
3Around the follicle. In skin research, GHK-Cu supports collagen and the matrix that holds skin together.
4A calmer scalp. It has also been studied for antioxidant and soothing activity in skin.

The science · 03
50 years of research.
GHK was first isolated from human plasma in 1973. Since then it's become one of the most studied peptides in skin science. Here's what researchers have looked at.
01Cell studies
Collagen
GHK-Cu prompted skin cells (fibroblasts) to make more collagen, even at very low concentrations.
02Skin research
Skin matrix
It increased decorin and glycosaminoglycans, the materials that keep skin structured and hydrated.
03Animal studies
Calmer skin
Treated skin showed lower markers of inflammation and higher antioxidant enzyme levels.
04Lab study · 2007
Copper peptides + follicles
A closely related copper peptide lengthened human hair follicles grown in the lab (Pyo et al., 2007).
These are studies on the ingredient, mostly in the lab, not clinical trials of this serum. We'll share our own product testing with the waitlist first.

The system
Lift. Feed. Now, target.
The shampoo clears the mineral build-up from the water. The conditioner seals each strand. The serum is the leave-in step that goes straight to the scalp once it's clean.

A chelating agent lifts calcium and magnesium so the scalp is clean.

Questions
Before the drop
01When does it launch?
Soon. Waitlist members hear first and get access before it goes public.
02How much will it cost?
We'll share pricing with the waitlist first.
03Do I need the shampoo too?
The serum works on its own, but it's designed as step three. Clearing mineral build-up first means the scalp is clean when the serum goes on.
04Is GHK-Cu proven to regrow hair?
No ingredient can honestly promise that. GHK-Cu has decades of skin research behind it, and copper peptides have shown promise for follicles in lab studies. We made the serum to look after the skin your hair grows from.
05Is it for men and women?
Yes. Like the rest of Regrowth+, it's made for every hair type.
