The one dream brand for hair products, one I love
I have been using Kérastase products for more than two years, and I can honestly say they have made a huge difference to my hair.
My hair was once dull, lifeless, thin, extremely rough and damaged after going through multiple treatments. I had tried different products, but I wasn’t seeing the results I was hoping for. Then I discovered Kérastase, and it completely changed my hair-care routine.
With consistent use, my hair has become much softer, smoother, healthier-looking and more manageable. It feels nourished and has regained a beautiful shine that I thought I had lost

Amazing Overnight Hair Serum – Visible Results by
I’ve been using the KER – 8H Magic Night Serum for my hair and I’m really happy with the results. The serum is lightweight and doesn’t feel sticky or greasy on the hair. I apply a small amount before going to bed, and by morning my hair feels much softer, smoother, and easier to manage.
It also helps reduce frizz and makes my hair look healthier and shinier. I like that it works overnight without needing to wash it out. After regular use, my hair feels more nourished and looks less dry. Definitely a great addition to a nighttime hair care routine!

Skin issue
I have never had a bad experience with any Kérastase products. I don’t have sensitive skin with any everyday products but this one has been a serious issue. My palms have had a bad reaction to this product and continue to outbreak only when I use this product. I’m not sure what ingredient is causing the reaction but for me this is a no go product.

8H Magic Night Serum
I’ve been using the 8H Magic Night Serum on my dry hair and I can genuinely see the results. My hair feels noticeably softer, smoother, and much more hydrated by morning. With the UK’s cold and dry weather, my hair usually feels brittle and dull, but this serum really helps lock in moisture overnight. Honestly, in winter conditions like this, it’s an absolute must-have.

Amazing serum
I absolutely love this night serum! From the moment I first tried it, the fragrance instantly stood out — a lovely, luxurious scent that’s noticeable but never overpowering. It feels like a treat every time I apply it.
The texture is light and non-greasy, gliding smoothly through my hair without leaving any heavy residue. I can even use it on slightly damp hair before bed, and it doesn’t feel sticky or oily at all.
By morning, my hair looks soft, smooth, and incredibly manageable. Frizz is noticeably reduced, and my strands feel nourished rather than weighed down. It’s quickly become a staple in my nighttime routine — a small amount goes a long way, and it genuinely keeps my hair feeling hydrated and healthy without that greasy finish some serums can leave behind.
