Strengthens hairHydratesSupports repair
An amino acid that supports hair strength and hydration, a small building block that helps repair-focused formulas work.
What it is
Arginine is an amino acid, and amino acids are the building blocks of the keratin that hair is made from. In haircare it supports the fibre's strength and moisture and complements larger repair proteins; in skincare it also acts as a gentle humectant and osmolyte.
How it works
Supports the fibre
As a keratin building block it helps support the strength and condition of hair, working alongside hydrolysed proteins in repair systems.
Hydrates
It attracts and helps retain moisture, improving softness and manageability.
The evidence
Arginine is well established as a supportive amino acid in both hair and skin care, valued for strength support and hydration.
Worth knowing
A small building-block ingredient that supports the larger repair proteins rather than acting alone.
