Review This Product

Wonderful oil! Now it is my favorite product. Hair after it became soft, crumbly, smooth and hydrated! He leaves no greasy hair, which is very good for me.

Alena, Russian Federation

This is my favorite leave-in product ever. It goes on so nicely and moisturizes the hair without leaving it greasy (the product itself is oily). It leaves my hair silky smooth and shiny, keeping the frizz down. The smell is an added bonus - I love it.

Sofia, Thailand

I love this product, it is absolutely fantastic, my hair is so soft and shiny...and blow drying is much easier after using it too...

I am addicted to this product and have been for about 6 years and I still love it, all my friends ask me how I keep my hair so silky and soft? :)

Anna, Latvia/Riga

It was my first Kerastase product. Re-ordered it again recently because it became my HG. Works great on my hair, doesn't make it look greasy at all. Also the smell is divine.

Lucy, Moldova

After use, my hair is really curly, very smooth and pleasant to the touch. It is also very economical. The effect is especially noticeable when I use a hair dryer or straightening iron. My must have!!!

I love this product! It does what it promises. It makes my hair super soft, shiny and eliminates frizz.
It does not weigh down my hair at all.
One of my favorite products now!

Kristin, Norway

My hair was getting really tangled and out or control, so after using so many products I can say this one is the best ever and I will be sticking with it for a long time. It makes my hair so smooth and silky, can't take my hands off. LOVE KERASTASE.

Maria, London

Great product to use before blow drying and even after a blow dry for that touch of sparkle! Hair is left smooth and looking great! I recommend!

Ruth, malta

I've always suffered with dry frizzy hair and colour my hair a lot. Since discovering Oleo-Relax Smoothing Serum, I can not go without. I use it on wet and dry hair and it makes such a difference. Less frizz and more shine. Love it!!!

Laura, Liverpool

Loooove this! My hair is so beautiful because of this! Just ordered a new one:)

Victoria, Oslo, Norway

I had unruly hair when I was growing up, for years I was bulied, my hairdresser saved me when they introduced me to Kerastase, I really will not use anything else and at this price, who can argue?!

Larney, Allum

A tiny amount of this product gives me that 'just been to the hairdressers' feel :) My hair is dry and curly and it works wonders! Also, If I could have a fragrance made of this scent it would be my ideal perfume!!

Ida, Glasgow

Amazing! I have struggled for years to find a product like this. I have frizzy hair and it now feels like velvet. Kerestase are my saviours!

SD, West Yorkshire

I have been struggling to manage my hair ever since I decided to grow it. I used to colour it regularly and my hair became really thin; each time after washing I would spend 10-15 minutes detangling it, much of my damaged hair would stay on the brush too... And then one girl gave a tester of this oil to me when I was buying shampoo. Honestly, it is the only thing that works for me, and it works great.

Marija, Lancaster

Do you want to discipline your dry unmanageable hair? Stop reading reviews! You should buy it immediately! I admire Oleo-Relax, it makes my hair silky for a long time, damaged ends received new life, two drops of oleo and hair relax love love love!!!

Olga, Russia

My dry hair feels like it has undergone a salon treatment; it usually only looks like this a few times a year!

Nadia, Leeds

I have used this product for about 3 years now. I don't imagine my hair without this oil. Since I have used it, I have cut my hair once in two years, but only 1 cm.

Lenka, Slovenia

I've tried a lot of products and this serum is the best for my thin wavy hair, to use with other creams or after blow drying. Makes your hair look shiny, smooth and frizz-free. It's always on my shopping list!

Karina, Brazil

This is the best serum ever. I have long, naturally wavy hair. I use this on damp hair. It leaves your hair super soft, frizz-free and light. You can also use it on dry hair for extra shine and protection from hot ceramic irons.

Mani, Netherlands

Kérastase products make my hair feel amazing.

Katy, London

This serum is wonderful! A few drops of this product and my hair became fantastic, soft and smooth! It is very economic, one bottle lasts about a year. I will never use any other serum or oil.

Inna, Dnepropetrovsk

This serum is amazing, best product! Makes my hair easy to manage and shiny.


Great product, makes my hair so soft and manageable.

Jie, Dublin

This serum smoothes hair without weighing it down and it lasts for ages so is definitely worth the purchase.

Reema, London

This serum made my hair amazingly soft, frizz-free and silky! Well worth the price.

Lisa, Northern Ireland

Love it! Leaves your hair straight, with a natural shine and beautiful flow.


This product is fantastic. It eliminates frizz and leaves my hair beautiful. I will not use anything else now!
