Penetraitt Leave-In Serum for Damaged Hair

Sebastian Professional’s Penetraitt Leave-In Serum targets damaged, color-treated hair with a lightweight, silky texture that detangles and smooths without weighing strands down. Designed for regular use as a leave-in treatment, it helps improve manageability and reduces breakage for brittle ends. Suitable for anyone seeking restorative styling support, it layers easily under other products and offers conditioning benefits without heavy residue.
