Smooth frizz and make rebellious hair more manageable with the Kérastase Serum Oleo-Relax. This expertly formulated, stylist-approved hair oil delivers lightweight hydration to dry ends while leaving hair with a smooth and shiny finish. The formula synergises a range of oils known for their nourishing, strengthening and glossing properties, successfully smoothing each strand of hair at the follicle to reduce the appearance of frizz, damage and split ends.

The oils moisturise dry strands without weighing hair down or making it look greasy, which is ideal for styling hair into gravity-defying looks and voluminous blow dries. Formulated with hair-calming ingredients, the oil relaxes unruly hair and detangles knots effortlessly without causing breakage. Use this oil to achieve long-lasting smoothness and shine, protecting hair from frizz throughout the day for salon-perfect tresses.

Kérastase offers a wide range of products that help you achieve salon-worthy results in your own home. This hair oil is easy to apply and offers high-performance. Use one to two pumps depending on how dense and thick your hair is. On dry hair, apply a small amount of product to the ends and smooth through the lengths. This product can also be used on wet hair as a hydrating and relaxing leave-in treatment, followed by shampoo and conditioner.

Not impressed

This oil is rather disappointing. Does not do anything for my hair other than weigh it down and make it greasy. Will not repurchase

The best I’ve found!

Despite trying many other products this oil is by far the best I’ve ever used. I always come back to using this. Plus a little goes a long way.

meh

I am a loyal Kerastase customer for over 7 years now and this is a product I won't be buying again. It doesn't compare to other serums/oils I have used both from Kerastase or Loreal Professionel. Giving 2 stars just because it is not an extremely awful product, but just a "meh" product. Regular coconut oil works way better.

Fab Serum

This serum really makes a difference. I have curly frizzy hair which is calmer and shiny after using this drum. I have used lots of other products but this is so superior. It's a life changing product. Cannot do without this serum now.

Wonder serum

I've used this serum for 5 years and it's amazing. Keeps my thick fluffy hair in check and tames fly always. Always leaves it feeling smooth and shiny, never greasy. Bonus is that a little goes a long way on damp hair or as a finishing touch after straighteners.

This Works

I tried this along with alterna c c caviar cream. To tame my frizzy hair. It works well , used sparingly it stops my hair frizzing up in the humidity. Excellent product , very pleased with the results, smells good too.

Unbeatable!

I have tried so many different hair oils as I have curly highlighted long thick hair. This product is perfect. It doesn't overload so never drags my hair down and I have had compliments about how healthy it looks. The smell is gorgeous (as is all their products) and I can honestly say it transforms my hair to a shiney mane!! I have my own business so don't need to stress about how my hair looks. This oil treatment definitely ticks all the boxes for me.

TOO MUCH FOR MY FINE 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.
