JPS LABO - Unlabel Lab Straight Keratin Control Treatment

DESCRIPTION

What It Does: Adsorbs to hair surface for superior conditioning, detangling, and static elimination.

Why It's Used: The premium quaternary ammonium conditioner – c22 chain length provides superior substantivity and lower irritation than ctab or dcdmh at equivalent conditioning performance.

How It Works: C22 quaternary ammonium adsorbs electrostatically to negatively charged hair cuticle (damaged hair has more negative sites, more adsorption where needed). forms a positively charged film reducing inter-fiber friction for detangling. c22 chain provides superior lubricant film vs shorter-chain quats. lower irritation than c16 ctac.

Typically Found In: Conditioners,hair masks,detangling sprays
