I have been using Kérastase Blond Absolu Cicanuit Night Serum for a while and am really positively surprised by the results. The serum has a light, creamy consistency that quickly absorbs into the hair without feeling heavy or sticky. It is easy to apply to the lengths before bedtime, and the scent is luxurious but not too strong.
When I wake up, my hair feels noticeably softer, more hydrated, and less frizzy. My blonde hair, which easily becomes dry and brittle, looks shinier and healthier after just a few uses. I also find that the ends feel stronger and less dry over time. A big advantage is that the serum does not weigh down the hair or make it greasy, even though it works overnight. In summary, this is a very good night serum for bleached or blonde hair that needs extra care, moisture, and repairing effect.
