"This advanced overnight leave-in serum brings skincare-inspired science into haircare, targeting visible signs of hair ageing while you sleep. Designed to act during the hair’s natural nocturnal regeneration phase, it delivers deep revitalisation to lengths and ends without weighing hair down. At the core of the formula is Pro-Xylane™, a green chemistry-derived sugar molecule known for reinforcing the hair fibre structure and improving density. Combined with Ochrophyta algae extract, a fast-growing marine active rich in minerals, the formula helps protect against daily aggressors while restoring vitality and resilience. The lightweight “quick-break” texture melts instantly into the fibre, ensuring even distribution of actives without residue. By morning, hair appears smoother, shinier, stronger, and visibly fuller. It addresses five key signs of ageing hair: dryness, dullness, frizz, lack of thickness, and loss of volume. The sensorial experience is elevated by a refined fragrance with layered notes of freesia, rose, bergamot, musk, and patchouli, transforming night care into a luxurious ritual."
