Pyunkang Yul Low pH Scalp Care 500ml

Pyunkang Yul Low pH Scalp Care 500ml is a rinse-out treatment built on a low pH formulation, designed to work with the scalp's natural balance rather than against it. Behentrimonium chloride and dipalmitoylethyl dimonium chloride provide the conditioning base, while onion bulb extract and biotin, alongside the amino acids cysteine and methionine, target damaged or brittle hair ends specifically. Menthol and grapefruit peel oil add a light, refreshing note during application, and sage leaf and camellia japonica flower extracts round out the botanical profile.
