Sebastian Professional Penetraitt Overnight Rescue Repair Serum

An overnight leave-in serum formulated with hyaluronic acid and niacinamide — the same star ingredients you'd find in a skincare routine. Penetrates deeply to help repair dry, damaged hair from within, working while you sleep for visibly healthier hair in 8 hours.

Best for: dry, damaged, brittle or colour-processed hair.

How to use: Apply 3–5 pumps to the palm of your hand and distribute evenly through damp or dry hair, from mid-lengths to ends. Do not rinse. Use overnight or as a treatment.
