Ingredient breakdown
What each ingredient does in the GHK-Cu shampoo.
This section uses the actual shampoo ingredient list. The formula is built around Copper Tripeptide-1, peptide support, hydration support, comfort support and a lightweight shampoo texture.
Hero copper peptide
Copper Tripeptide-1
Copper Tripeptide-1 is the GHK-Cu hero ingredient in the shampoo. It connects the wash step to the wider CopperTheory haircare story around scalp health, hair growth support, thicker hair and fuller density.
Peptide support
Acetyl Hexapeptide-8
Acetyl Hexapeptide-8 strengthens the peptide profile of the shampoo. It supports the formula’s positioning as a more advanced haircare step inside the full GHK-Cu routine.
Hydration base
Butylene Glycol + Glycerin
Butylene Glycol and Glycerin support hydration, slip and a more comfortable wash feel. They help the shampoo feel less basic and more aligned with a scalp-care routine.
Hyaluronic support
Sodium Hyaluronate + Hydrolyzed Sodium Hyaluronate
Sodium Hyaluronate and Hydrolyzed Sodium Hyaluronate support hydration and a smoother, more comfortable scalp and hair feel after washing.
Scalp comfort support
Panthenol + Niacinamide + Allantoin
Panthenol supports softness and comfort, Niacinamide supports a stronger scalp-care story, and Allantoin helps the shampoo fit a more comfortable daily or regular wash routine.
Formula structure
Arginine + Xanthan Gum + Carbomer
Arginine supports formula balance and haircare positioning. Xanthan Gum and Carbomer help support texture, while Triethanolamine, Disodium EDTA and supporting ingredients help formula performance.
