The hair dresser always uses kerastase serum. Different hairshop different disigner but they use same product therefore it's evidence for the product quality!

This leaves my hair so shiny and silky every time I use it. It also smells amazing. I highly recommend this for anybody with dry frizzy or damaged hair.

Not better than my expectable. But it useful if the hair is dry. This product can be used for a long time.

My hair gets dry and frizzy in the humid weather. This serum helps to detangle my hair after wash, it smoothens my hair with just one pump :) I love the feel and smell of my hair!

I have been a huge fan of this product for years! It's the only thing that works on my hair. I always get compliments on my hair when I've used it. The price on here is really good and the delivery is always so quick!

Fast and efficient delivery. The product is quite effective in taming frizzy hair and adds a shiny touch to my hair. Definitely a good buy considering the consumer-friendly price and the quality of the product. Would recommend it to my freinds who have similar hair problems with me.

I have very curly and think hair that is only controlled by straightening. This product is the only thing on the market that keeps it under control. Use on towel dried hair :)

An excellent product and have used it for years. Leaves your hair shiny and smooth. Very good price from this company, can't beat it anywhere.

I really love Kerastase products for my curly, unruly, frizzy mop! I use both the Nutritrive Curl and Relax products and find that this serum works well with both. It really does help to control my hair and to keep the frizz at bay.

This product delivers exactly as it promises - smooths fine, dry hair leaving hair manegable and beautifully smooth and shiny. As I have very fine and wavy hair myself, I have at times felt in despair after investing in many products that have proved to be nothing but a disappointment.
Thankfully, this product is not one of those. It seriously delivers everything it says it will, and always leaves me feeling confident and thrilled with the outcome!
All Kerastase need to do now, is to develop a product that's effect on hair is semi-permanent. When they develop this, a product that produces an effect that turns wavy hair into a manegably soft and shiny body wave that is semi-permanent, guess who will be standing at the front line waiting to purchase this - you've got it - me!
Thank you Kerastase :-)

Love this product and have introduced to my friends and they buy it also. If they can offer economy size is better.

After trying most of the Kerastase products... this is by far the best for my dry hair, i have been purchasing this range for years and none of the new kerastase products compare....
23 December 2014 by
I usually love Kerastase products but I'm not sure about this one, it's the first time I have used it and other, cheaper serum's do just as good a job. Not sure I will buy it again.
10 December 2014 by
I used this product several times. It is really good for hair with awesome smell!!
5 December 2014 by
I love the product but wasn't pleased as my delivery was put in the wheelie bin not very practical as it was bin was the next day and if I had been away it would of been gone!!!!!!

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.
2 September 2014 by
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!
1 July 2014 by
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.
27 May 2014 by
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
18 April 2014 by
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.

25 February 2014 by
This product is perfect! Make my hair smooth and shiny. Wanna buy again
27 January 2014 by
The product does make the hair softer. The light texture make it competitive with the oil-products option.
13 December 2013 by
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!
6 December 2013 by
This serum is great and left my hair feeling silky soft. Although it is pricey, it lasts ages and is definitely worth investing in!

Perfect produkct.leaves haid smooth and soft
4 November 2013 by
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
24 October 2013 by
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!
24 October 2013 by
Excelente I loved this product I recommend.
22 October 2013 by
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.
18 October 2013 by
I love this product! It doesn't make my hair greasy but makes sure my frizz stays controlled all day:)
15 October 2013 by
Just use some Kérastase Sérum Oléo-Relax when curly hair is almost dry. Fabulous!
15 October 2013 by

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!
27 September 2013 by
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.
1 September 2013 by
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!
16 August 2013 by
This hair Kérastase Sérum Oléo-Relax does absolutely what it says on the bottle. Gives fuzzy dry hair a sleek shiny look.
14 August 2013 by
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.
