Kérastase Discipline Oleo-Relax Hair Smoothing Oil | 3.4 oz

Tame frizzy, voluminous, and unruly hair with salon-grade precision. Kérastase Discipline Oleo-Relax Advanced Hair Smoothing Oil is a luxurious, lightweight control oil that delivers lasting smoothness, brilliant shine, and total frizz elimination — without weighing hair down or leaving any greasy residue.

This advanced smoothing oil is formulated with Morpho-Keratine™ and Marula Oil — a rare, fast-absorbing botanical oil from the Marula tree known for its exceptional ability to smooth the hair cuticle and lock out humidity. Morpho-Keratine™ reinforces the internal hair fiber for long-term discipline and shape retention, while Marula Oil penetrates quickly to deliver intensive nourishment and a high-gloss finish. The result is hair that is visibly smoother, less frizzy, and perfectly manageable from root to tip — even in high humidity conditions.

Apply to towel-dried or dry hair before styling. Work a small amount through mid-lengths and ends, then blow-dry or air-dry as desired. Can also be used as a finishing serum on dry hair for extra shine and flyaway control. Each 3.4 oz bottle provides generous use for regular smoothing treatments.
