Krastase Nutritive Nutri-Supplement Split Ends Serum is a leave-in oil serum created to care for dry hair and fragile ends. The lightweight, translucent texture is enriched with a vitamin-in-oil blend, plant-based proteins and niacinamide to help replenish lipids, smooth the cuticle and support stronger-feeling lengths. Hair is left feeling softer and more supple, with a satin-like shine and a more polished look to split ends.

Ideal for dry, damaged or breakage-prone ends, this serum fits easily into an existing Nutritive routine or any nourishing haircare ritual. Its designed to be applied after washing and conditioning, or on dry hair between washes, to give tips an extra boost of care. With regular use, it helps to reduce the look of split ends, tame frizz and enhance shine, so hair looks better maintained between salon trims.
