I use on my ends on day two hair and use at night. It’s seriously the best.

Great product! This is for dry, frizzy hair. Ladies over 50, hair can take on a more frizzy texture when hair is gray (even if you color your hair it still has the texture of gray hair).I have thinner hair but a ton of it and this tamed the frizz without a tacky texture. Add too much in and it will weigh your hair down. Smells fresh but is on the stronger side, if worried smell before you buy. I put it on my ends and the top layer of my hair that always seems to be the focus of my frizz

High hopes but strong scent and poor results

If you want your hair to smell strongly of men’s deodorant, this is the overnight hair serum for you. Beyond the scent, it’s just not as good as the Nutritive overnight serum. I’ve been using that for years and loved it so thought this would be a perfect change, since I’m getting older. However, it didn’t make my hair soft and shiny like Nutritive does - I didn’t notice any benefits. I’d get over the smell if the results were great, but they’re not. I’m passing this bottle on and going back to my beloved Nutritive. Kerastase, your hero serum is sooo good, what happened here???

This is a gimmick

I bought the entire line: shampoo, mask, detangle spray and this overnight serum and what I noticed most is how badly it dried my hair out. I tried them all individually and together to see if it was one item or all of them but no matter what combo, if one of these products was in rotation, my hair was straw. For reference, I have medium thick, mostly straight, partially bleached hair. I have other Kerastase products that I love but this entire line wasn't it

Smell it, you’ll be hooked

The smell alone made me buy it. But I kept it because it works well. Don’t listen to the directions. You can put it on day or night, anytime you want. It leaves my hair smooth but not at all weighed down. Gorgeous product

Smells like a man cologne - too strong of a scent.

Barely using this because the smell is awful. I don’t want to smell like a man. Remove the fragrance or change it to a normal light vanilla scent that is good for bedtime. Stuck smelling this man scent all night :(

Not a good buy

Didn't do anything for me. Followed the instructions, used at night, small amount and it just didn't work. Didn't leave hair smooth or tamed at all.

Won’t be without it. First hair serum & it’s magic

My colored hair was looking flat and my ends felt like straw. I rarely use heat on dry my long, fine low porosity hair and it had just been trimmed yet on a recent NYC trip the frizz was unstoppable. a . A kind Sephora associate recommended it. I will never be without it. After a few days my hair was incredible. I could care less about the small! It’s fine.
