Nutritive Split Ends Hair Serum
Kerastase Nutritive Split Ends Hair Serum targets dry, split ends with a sealing blend. I use it on damaged ends after trimming. It forms an ultra-sealing layer that smooths and glazes the tip, making ends look healthier and shinier immediately. The formula uses anti-dryness polymers and light oils.
After application, hair looks polished and split ends sit together more neatly. It does not replace a trim, but it hides damage and prevents further split progression. I often layer it under styling products for a long-lasting glossy finish.
Pros:
- Seals split ends for a smoother look
- Reduces the appearance of dryness and breakage
- Lightweight, non-greasy sealing effect
- Gives a glossy finish to tips instantly
- Works well under styling products
Cons:
- Does not replace professional trimming
- Effect is cosmetic; needs regular reapplication
