Scalp Theory
AHK-Cu Copper Peptide Scalp & Hair Tonic · 30 ml / 1 fl oz
The ritual
Part the hair to expose the scalp in sections.
Apply directly to a clean, dry or slightly damp scalp. Do not rinse.
Massage in and style as usual. Use morning or evening, daily.
The science behind every drop
Most tonics address one variable. Scalp Theory addresses three: the follicle, the environment around it, and blood flow to it.
The hair-specific copper peptide, studied for follicle support and scalp repair signalling.
Gently exfoliates the scalp and clears follicle-blocking buildup.
Supports circulation and blood flow to the follicle.
Chosen with intention, down to the glass
Bottled in amber glass that shields light-sensitive copper peptides, with a precise dropper. Small-batch and batch-coded, so every bottle is traceable. Copper peptides and caffeine work gradually — this is a long-term scalp-health protocol, and consistency matters more than speed.
