Rated 3 out of 5 by from Great shine I bought this serum to help control slight frizz issues with my straight Pacific Islander hair and itchy scalp. I found it to be too oily for my scalp so I decided to use 2 to 4 pumps just mid to ends of my hair. I have naturally oily scalp so this probably didn’t help. So I’m giving it a 3 only because I’m really hoping to find something that did it all for my hair issues. I use a natural mask now that is inexpensive and works great along with Kerastase oil serum

Rated 5 out of 5 by from The Real Deal The reviews for this oil are true. It will make your hair smooth, shiny and manageable. For reference I have biracial hair that is closer to Black texture and I wear extensions. I use only Kerastase products. I use the Extentioniste shampoo and mask, or the Nutritive line of shampoos and conditioners. I applied the Nutritive thermique blow dry serum and this oil and proceeded to blow dry my hair. My hair came out so shiny and smooth I did not have to flat iron it. That has never happened in my life. No frizzy ends, no rough patches. I seriously love this oil.

Rated 5 out of 5 by from Kerastase Oleo-Relax > Paul Mitchell Super Skinny I just got this today and I'm already in love with it. When it finally shipped to my home, I decided to try it since my hair felt a little on the brittle side today. I did two pumps and man, was I shocked. My hair just about transformed for brittle to smooth, soft locks. Did not weigh down my hair one bit, and it absorbed very fast. I still love my Paul Mitchell serum, but this one works better. I'll use this an every-once-in-awhile treat for my hair since it's quite pricy. I can't wait to see and feel my hair after I blow-dry with this! Thank you, Kerastase!

Rated 5 out of 5 by from Magic I bought this about 3 weeks ago, and I don’t really write reviews, but this stuff is amazing. I have very thick, wavy, coarse, unruly hair. I have tried SO many products, but nothing makes my hair behave like this. I put on one pump, then dry (straight OR curly) then add another on the mid lengths to ends to finish. On the second and third day I just add another pump and comb through. My hair feels like someone else’s hair. It’s SO silky, and bouncy! I can’t stop touching it! It looks so healthy and shiny. It also smells really great! Please don’t ever stop making this.. it’s amazing!

Rated 5 out of 5 by from a GAME CHANGER! First off, I want to state that I new usually write reviews. I have written a handful of reviews and that’s only for things that absolutely wow me. With that being said...this hair oil is PHENOMENAL! It smells wonderful, feels silky smooth and makes my hair turn heads. I dont use this while my hair is wet like it states. Instead I use Kerastase’s Ciment Thermique, go on to blow dry my hair and after...I take 2-3 pumps and run this all through out my hair. I have long, thick hair. So BAM! My hair is then sexy, smooth and sleek. It doesn’t have a greasy feel it’s very natural. It’s weightless so your hair still has bounce and movement. This will always be in my possession at all times. It’s such a crucial element to my styling process. 10/10 will recommend to everyone and anyone!

Rated 5 out of 5 by from WOW - Will change your hair! I started using this a month ago and would not write a review until I had at least a month of usage. Honestly - it transformed my hair immediately. I am Black with kinky "nappy" hair. This straightens my hair and makes it extremely manageable. When I use it, my hair holds the style. It is also great to use as a refresher in between shampoos. I LOVE, LOVE, LOVE this product! It is highly recommended by so many people for a reason. If you have not tried it - try it! You will be highly impressed.

Rated 5 out of 5 by from The best hair oil available! I love the Oleo-Relax serum. I’ve used it for 10 years and although I’ve tried other high end brands, this remains my favorite. It dramatically helps keep frizz and dry ends on my long, thick hair look and feel great! I put it on before I dry my hair and again afterwards just on the lower third of my hair. A bottle lasts almost a year!

Rated 5 out of 5 by from Hands Down, The Best Hair Serum Amazing product, hands down the best hair serum I've ever used. I have very dry, frizzy hair, but tend to get oily at the scalp so it's been a challenge to find something that could smooth fly-aways and soften my hair without making my hair greasy. Oleo-Relax is the only one I've ever found that does all of that! It's so light weight and non-greasy that I can add more to my hair each day between washings without looking like an oily mess. As others have mentioned, the scent is wonderful and not too overpowering like some of the other product fragrances out there. I highly recommend this serum! (and just in case any Kerastase employees are reading this, please PLEASE don't ever discontinue this product)
