Couture hair doesn’t start under hot tools — it starts the night before. Demi Moore’s sleek blowout at the Schiaparelli show in Paris is prime evidence.
The quiet prep behind the look came courtesy of celebrity hairstylist Dimitris Giannetos, who pre-treated her hair with Kerastase Nutritive 8H Magic Night Serum, a formula designed to soften, hydrate and refine the hair’s texture overnight to make for a red carpet-ready blowout come morning. For anyone chasing that refined, swishy blowout Moore is known for, this serum acts as the foundation. It repairs and conditions strands while you sleep, so your morning styling routine feels faster, easier and far more luxurious.

Formulated for dry and depleted hair types, the 8H Magic Night Serum delivers up to eight hours of continuous hydration without leaving hair greasy or flat. It has a silky, fast-absorbing texture that melts into lengths and ends, helping to reduce that crunchy, parched feeling that often shows up after heat styling or color treatments. By morning, hair feels more supple and flexible, resulting in smoother and more polished blowouts.
To use, apply the serum to dry or slightly damp hair before bed, focusing on the mid-lengths and ends and avoiding the roots. Use one to two pumps, depending on hair thickness, then gently work it through with your fingers. Leave it in overnight — no rinsing required — and style as usual in the morning.
The serum has earned a loyal following among over 1,400 Amazon reviewers who gave it five stars. One reviewer said it left hair feeling “soft, smooth and hydrated by morning without feeling greasy,” while another shopper said it “strengthened [their] hair” and “reduced breakage.”
For anyone looking to invest in hair care that prioritizes long-term softness and manageability over quick, high-shine fixes, the Kerastase Nutritive 8H Magic Night Serum offers a smarter approach. Shop the overnight serum now and see how a simple nighttime step can make polished, glossy blowouts feel effortless the next day.
