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???

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 :(

Frizzy and dry
I’m almost done the bottle and I have to say I’m not a fan. The smell doesn’t bother me but I feel like this has made my hair drier and I’m noticing my hair is more frizzy all of a sudden and this is the only new thing added to my routine. So I’ll be switching back to the Kerastase Nutritive 8hr magic serum

great!
I thought this might make my hair greasy, but it doesnt. I wake up, my hair feels softer, stronger. And, less seems to come out during the morning.

Buy it!
I’m on day 2 of using this luxurious serum. It smells divine and it’s so silky. I woke up with much softer hair. Consistency is key. 🔑
