Key Ingredients
Plant-Based Proteins
Key ingredients in this overnight hair serum, wheat, corn, and soy whole grains act as a dietary supplement blended with fatty acids, omega, and vitamins to feed the hair with essential nutrients
Niacinamide
This is a derivative of vitamin B3 that locks in nutrition, strengthening the fiber barrier for long-lasting health.
Glycerin
From vegetal origin, glycerin boosts the global hydrating performance of the formula.
Kérastase discovered that dry hair issues come from a lack of nutrients happening at 3 different stages: scalp, lengths & ends.
When hair becomes dry, the cuticles are damaged, and the fiber loses its essential building blocks – proteins and lipids.
Nutrient Deficiency
Scalp Stage
Lack of proteins, fatty acids and vitamins.
Lengths Stage
Low level of nutrients + weak protective barrier.
Ends Stage
Very low level of nutrients + chapped cuticles.

Nutritive Addictive Scent
The work of an accomplished nose, the Nutritrive scent is an iconic floral fragrance with two cult scents – a powdery, fresh one and a musky, feminine one providing a nostalgic feel, embellished by a third captivating floral scent. Violet leaves and ylang ylang form its floral heart, with tonka beans and white jasmine atop a white cedar and sandalwood base.

Hair feels and look healthy and strong. IncredibleMy new favourite serum. After only 2 uses, I can’t believe the difference! The mids and ends of my hair used to be very dry and due to heat styling I had split ends and broken hair shafts. The before and after serum difference in my hair texture is incredible! My hair now feels so soft and appears shinier & healthier. This serum is now part of my hair care. Thank you for the free sample ❤️

Amazing product!After only a couple of weeks of use, I can’t believe the difference! The mids and ends of my hair would tend to be quite dry as it is highlighted hair. The before and after serum difference in my hair texture and appearance is incredible! My hair now feels so soft and appears shinier & healthier.

Good but expected a bit moreBeen using about 4-5 pumps every night. The smell is amazing, but that is about it. I expected more conditioning or more slip. My hair is on the thick, dry side, and I use a lot of heat styling. I think an oil might be better suited for me. I will be using the rest of the bottle, but my next purchase will be an oil for sure.

Amazing results in 2 weeksI've had fantastic results in just a few weeks of use. I have colored/balyaged hair which tends to be very dry on the mid-lengths and ends. I started using the 8-hour overnight serum 2 weeks ago and it's amazing the difference in my hair texture and appearance. The dryness has resolved and my hair feels incredibly soft and looks shiny & healthy. I combine using the 8-hour overnight serum with 2 pumps of the Elixir Oil. It leaves no greasy residue and does not weigh down my hair. I absolutely love it!
