Lightweight yet rich in restorative ingredients, the product is designed to be applied on towel-dried hair before styling or used as a finishing touch on dry hair to tame flyaways and disguise split ends.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this serum rebuild very damaged hair?\u003c\/h3\u003e\n\u003cp\u003eThe formula combines targeted actives that work on hair structure and surface. Gluco Peptide helps fortify the existing fiber, while a wheat protein derivative improves elasticity and flexibility so hair resists breakage during styling.

KÉRASTASE specifies protection up to 450°F (about 232°C), which covers most blow-dryers, flat irons, and curling tools when used as directed.

For dry hair, a small amount can be smoothed onto surface areas to control frizz, conceal split ends, and add shine.

The lightweight texture avoids greasiness while delivering a nourishing finish that improves comb-through and reduces visible damage at the tips.
