Sebastian Penetraitt Repair Masque is a deep conditioning treatment designed to restore and strengthen damaged hair. This intensive formula penetrates the hair shaft to rebuild resilience and nourish from within, leaving hair feeling soft, smooth, and healthy. Ideal for revitalizing over-processed, dry, or brittle strands, it helps to protect against future damage and improve overall hair texture and shine. Apply generously to shampooed, towel-dried hair. Leave on for 3-5 minutes, then rinse thoroughly. Use weekly or as needed for best results.
