The Sebastian Professional Penetraitt Conditioner is an intensely moisturising formula designed to protect and visibly repair the look of dry, colour-treated hair to reveal a soft and stronger-looking finish. The formula protects against visible split ends and breakage by plumping strands with moisture, resulting in a fuller appearance. Hair feels noticeably smooth post-use with a high-shine, glass-like lustre. For best results use as part of the Penetraitt routine.
