Actress Demi Moore’s hair stylist, Dimitris Giannetos, employed Kérastase’s Nutritive 8H Magic Night Hair Serum to create the radiant shine seen on Moore’s hair at Schiaparelli’s Spring/Summer 2026 Couture Show. This overnight serum, known for its ability to soften and strengthen hair, has helped hundreds of shoppers notice faster hair growth. The Demi Moore glossy hair serum has become a sought-after treatment for those looking to improve their hair’s texture and shine. Alongside the serum, Moore also used a hair oil and a shine-enhancing shampoo and conditioner to complete her lustrous look.
The Science Behind the Overnight Hair Serum
The Nutritive 8H Magic Night Hair Serum combines plant-derived proteins and niacinamide to deeply hydrate and nourish hair strands while locking in moisture overnight. Applied before bedtime, the treatment instantly adds shine, creating a silky, glass-like finish. Upon waking, hair feels softer, detangled, and noticeably smoother, which helps reduce frizz and prevent bed head. This serum has become an essential remedy for dry winter hair, providing much-needed hydration without requiring significant changes to damaging hair routines.
Reports of Faster Hair Growth and Repair
Users of the serum have reported impressive benefits beyond immediate shine. One shopper recovering from severe hair loss said their hair is now
growing so fast and, most importantly, [is] healthy.
They credited the serum with moisturizing their hair effectively, which in turn helps with thinning and breakage. Another person recovering from extensive bleaching treatment shared that their hair strands are
finally growing and regaining shine.
These accounts highlight the serum’s potential to promote hair strength and encourage new growth, reinforcing its value as a restorative haircare option.
Additional Kérastase Products That Complement the Serum
While the Nutritive 8H Magic Night Hair Serum is a premium product with a corresponding price tag, many believe it is worth the expense for both short- and long-term results. For those inspired by Moore’s hair transformation, Kérastase offers additional celebrity-favorite products including nourishing hair oils, and shine-boosting shampoos and conditioners. These combined treatments work together to maintain moisture, enhance gloss, and protect hair from winter’s harsh effects, potentially leading to stronger, shinier hair over time.
Why This Serum Matters for Hair Health
For those struggling with dry or damaged hair, especially during colder months, the Demi Moore glossy hair serum presents an effective option to restore vitality without drastic lifestyle changes. Its formula addresses hydration, strength, and smoothness, while anecdotal evidence supports its role in accelerating healthy hair growth. As the industry continues to evolve, treatments like this serum offer hope to many seeking both immediate shine and lasting repair.
