It is very great! Work to smooth and nourish unmanageable hair.
My hair is very fine, long, curly and coloured, with damaged ends. I tried this product both on damp and dry hair, but I feel it is too much for my fine hair: it left my hair heavy and after few hours the ends were really dry. I keep using lots of Kerastase products, I love the brand, but, in my opinion, this is not the suitable product for fine hair, even if damaged and dry.
This is excellent on dry and frizzy hair, but on other hairtypes it may be little too much. It makes hair very manageable and soft. It is good product, but too much for my hair, thats why I will use similar product - Kerastase Fluide Chroma Riche.
Gread serum, my hair are soft and shining after using it!

Along with the mask and shampoo, this has done wonders for my hair which was practically dead from my hair straightener. It keeps my almost afro hair under control. A bit on the pricey side, but products I definitely recommend.
This serum has really helped smooth out and tame my very frizzy and coarse hair. I do have thin-ish hair and I've noticed that I can very easily over use it and then it just ends up weighing my hair down. The product itself has a very strong rosey scent, which I don't mind, but if it's something you know that'll bothers you then you might not want to buy it.
smoothing serum to my discipline fine dry
I love this product, I have very fine hair and its naturally curly and the damp weather and makes it go all fizzy but with product i can leave the house in the morning knowing my hair is going to look great all day and it gives it a lovely shine without it looking greasy and the price is great too and it lasts for ages.
hair oil wonderful. hair after him brilliant, well-kept, as after visiting a beauty salon. I use it quite a long time and regularly. really like and recommend to everyone.
This product is perfect! Make my hair smooth and shiny. Wanna buy again
The product does make the hair softer. The light texture make it competitive with the oil-products option.
Impressed with this oil. Was after an oil product that wouldn't cost a fortune for a small amount. Have very thick curly hair & wanted something light weight, that would still nourish dry curly hair without weighing it down & making it greasy. Lovely smell too!
This serum is great and left my hair feeling silky soft. Although it is pricey, it lasts ages and is definitely worth investing in!
Leaves hair really shiny and smooth, i already got lots of compliments on my hair when i used this product. But be careful not to use too much! I think it really helps to reduce volume and to prevent the hair from being frizzy. Although i would always recommend to use a spray or a oil on top, like the redken argan oil or the goldwell diamond gloss style spray.
Kérastase Sérum Oléo-Relax is tried and tested! wonderfull! my curly hair doesn´t go up up like other humid days brilliant combating frizz and smoothing! buy again and again
I tried this Kérastase Sérum Oléo-Relax as I'm a big fan of Kerastase Ultime Elixir. I found this product to be good at taming frizz, however the results were that my hair was extremely soft and limp, which resulted in it being unmangeable for fine hair. I would stay stick to the Ultimate Elixir if you want manageable, smooth and shiny hair!
Love this oil. I have thick hair but my ends can get dry. It's not too greasy that it will weigh my hair down and the ends of my hair is soft and moisturized.
I love this product! It doesn't make my hair greasy but makes sure my frizz stays controlled all day:)
Just use some Kérastase Sérum Oléo-Relax when curly hair is almost dry. Fabulous!
This Kérastase Sérum Oléo-Relax is a great product. Highly recommended.
Very good oil. Makes hair manageable, soft. Hair shine.
This Kérastase Sérum Oléo-Relax makes my hair come alive!
Hands down, this Kérastase Sérum Oléo-Relax is the best serum for dry, coarse hair! I have curly, frizzy coarse hair and I have finally found my holy grail!
I used Kérastase Sérum Oléo-Relax on wet hair and after brushing my hair it is left really light and smooth!! On dry her it adds a shiny touch.
The Kérastase Sérum Oléo-Relax is an amazing product that tames my frizzy hair perfectly! Love it!
I just have one word for the Kérastase Sérum Oléo-Relax - amazing!
This hair Kérastase Sérum Oléo-Relax does absolutely what it says on the bottle. Gives fuzzy dry hair a sleek shiny look.
I live in a country where humidity is 80-90% during the summer months, so you can imagine what it does to thick hair! Unfortunately I didn't find this Kérastase Sérum Oléo-Relax a miracle product like a few other reviews have said, but it smells and feels lovely on the hair whilst taming it a little bit.
I have a lot of hair, and this Kérastase Sérum Oléo-Relax works as a charm, however I'm not happy with the smell. Too girly.
Fast delivery and solid package. This Kérastase Sérum Oléo-Relax is absolutely great and fits for my hair.
I love the Kérastase Sérum Oléo-Relax (125ml), it makes my hair feel like silk! A little goes a long way, so the bottle lasts a long time. The serum controls the hair and adds shine. Fast shipping, I plan to re-order when I have run out. Thank you very much.
This Kérastase Sérum Oléo-Relax gives my hair the best shine, it feels nice and soft and not so dry. I tried several other products like this one, but this one is certainly the best!
This Kérastase Sérum Oléo-Relax oil for dry and frizzy hair is just excellent. I've long searched for an oil for my dry and frizzy hair, and I've finally found it! I blow dry my hair and straighten it often, so it helps your hair to last longer as well. A really good product, and I highly recommend it!
The Kérastase Sérum Oléo-Relax is the one haircare product that I literally can't live without, it transforms my slightly dry and frizzy hair into sleek and manageable tresses without fail. I simply love it!
This Kérastase Sérum Oléo-Relax is absolutely wonderful! Highly recommend the company and the product.
I am satisfied with this Kérastase Sérum Oléo-Relax product, it is not greasy and has a pleasant smell. It's good for my dry hair! I am also very pleased with the services, shipment and the fact that it arrived in a reasonable time.
This Kérastase Sérum Oléo-Relax is just excellent for curly hair.
This Kérastase Sérum Oléo-Relax is a wonderful softening product that restores shine to over-treated hair. It is really good value for money as it lasts for such a long time - you only need to use 2 pumps maximum per wash before blow drying otherwise it actually makes your hair too floppy and lank. It's worth very penny and had made my hair shine again for the first time in ages!
