The why

Best for Frizz
Leave-In Molecular Repair Hair Mask
K18·Leave-In Conditioner
See alternativesFour-minute leave-in treatment; no rinse
- Size: 50 ml
- Price per ml: $1.50/ml (original $0.26/ml)
The why
A leave-in peptide treatment with SH-Oligopeptide-78 and Hydrolyzed Wheat Protein, designed for chemically or heat-damaged hair. Best for brittle, bleached lengths needing strength rather than daily hydration. Overuse can leave fine hair dry, stiff, tangled, or limp.
One minus
Protein-overload complaints: stiff, brittle, dry hair
“I also will sometimes use K18 leave in treatment to solve this look, and skip all other styling products for a couple washes (week or so).”
