PRODUCT DETAILS

Finish your Truest by S FREE repair routine with this luxurious hair oil — a silicone-based treatment that coats each strand in a protective layer of smoothness and shine. Formulated with the same acid and heat care complex as the range, this oil works on two levels: the silicone base provides immediate surface smoothness, while the Keratin, Silk, and botanical complex continues repairing damage from within. Glyoxylic acid and levulinic acid realign damaged hair proteins even in an oil format. Perfect as a finishing step after styling, as a pre-wash treatment, or applied to damp hair before drying. Sleek, polished finish with protection against daily heat.
