Key Formulation Details
According to the product labeling, this overnight hair serum is infused with plant-based proteins, niacinamide, and glycerin. It features a liquid consistency and is specified as unscented, making it a neutral option for those who are sensitive to strong fragrances in their beauty regimen. This formula is targeted toward users seeking targeted nighttime hydration without added perfume notes.
Intended Audience and Hydration Benefits
The primary intended audience for this overnight serum consists of individuals dealing with dry hair that lacks moisture and luster. Kérastase claims that this liquid formula restores fiber hydration during the night. By working continuously over an eight-hour period, the product targets dry fibers to restore a radiant, youthful hair appearance by the time you wake up in the morning.

Friction Protection During Sleep
A unique aspect of this hair serum is its design to protect hair from pillow friction. Sleeping can often cause physical stress, static, and tangling to fragile hair strands. The manufacturer highlights that applying this serum before bed establishes a protective barrier that actively guards against this friction, helping to maintain smoother, healthier strands throughout the night.
Manufacturer Claims on Frizz Reduction
Among the primary benefits highlighted by the brand is a significant reduction in frizz. Based on an instrumental test post-application of the 8H Magic Night Serum, the manufacturer claims the product leads to 84% less frizz. This overnight treatment is designed to leave hair feeling remarkably smoother, more controlled, and easier to manage when morning comes.

Supported Drawbacks to Consider
One of the most notable drawbacks of this product is its high price point, retailing at ₹8,800.00, which represents a substantial investment for hair care. Additionally, because it is specified as unscented, consumers who associate high-end salon products with luxurious, long-lasting fragrances might find the lack of scent disappointing. Finally, the pack size includes two items totaling 180ml, which might be a larger commitment than some users prefer for a trial purchase.
Customer Ratings and Market Standing
Despite the premium price, the serum holds a strong market position, ranking #63 in Hair Styling Serums and #6,524 in the overall Beauty category. It has achieved a highly favorable customer satisfaction rating of 4.6 out of 5 stars. This rating is aggregated from a substantial volume of 8,844 customer reviews, suggesting a highly positive reception among its international user base.

The Kérastase Nutritive 8H Magic Night Hair Serum is an intensive overnight option best suited for those willing to invest in premium, luxury hair care. While the cost is high, the combination of friction protection, frizz control, and fiber hydration makes it a robust solution for individuals with dry hair looking to revitalize their hair's texture while they sleep.
