While you sleep, your hair recovers. Sebastian Penetraitt Overnight Repair Serum works overnight, when hair is most receptive to deep care. Its texture is light, silky, and invisible on the hair. Apply, distribute… and it works silently until morning.

This nighttime serum was developed for ultra-stressed hair, damaged by coloring, heat, mechanical aggressions, or daily wear and tear. Its leave-in formula helps restore smoothness, strengthen the hair fiber, and restore manageability to the hair, without the need to rinse or wash.

Upon waking, your hair feels different. Softer. More manageable. Visibly regenerated and ready for styling. It doesn't weigh hair down, leaves no residue, and doesn't alter the hair's natural texture. It only improves… night after night.

For those seeking practical and effective at-home care. For professionals who want to recommend a high-performance overnight treatment. A true ally in the recovery of damaged hair — while you rest.
