Rated 5 out of 5 by from Magic in a bottle! Okay first thing's first...we have to talk about the fragrance of this serum. It is so fresh and delightful that I literally sit and smell my own hair throughout the day when I use this. I know people have to think I'm weird! I don't care. It's that good. Moving on to how it performs. My hair is fine but I have a lot of it and I get some frizz that definitely has a mind of its own. A little bit of this serum on my frizzies before blow drying helps to smooth my hair and keep it supple. A little drop after flat ironing (a LITTLE drop) rubbed between my palms and smoothed just over the most troublesome frizzies and ends keeps my hair under control but not heavy. I adore this product.

Rated 5 out of 5 by from LOVE IT This is, hands down, the best serum I've ever used on my hair. I started off using it as just a hydrating and repairing oil, but my stylist recently told me to use it when I straighten my hair to achieve a silky smooth look (duh, I can't believe I didn't think of that). The BEST part is that I've had it for about three months and I only use one pump each time I use it, so I have only used like 1/8 of the bottle. This is definitely a product that will be worth your money! Also, just a side note, I have hair that gets oily really easily even though it's dry (it's like my hair can't absorb the oil) and this does not leave me oily at sinks right in!

Rated 5 out of 5 by from Fabulous!!! I just finished my first bottle of this amazing product and just ordered my second bottle. This is the best smoothing/straightening product I have ever found for my frizzy, damaged hair. I NEVER want to be without this product! My Kerastase salon told me they are no longer able to stock this product as it has been discontinued?!? I certainly hope that's not the case. This product is absolutely amazing and life changing for me and the reviews speak for themselves! I would be absolutely heartbroken if this product is no longer available. Are you listening, Kerastase?

Rated 5 out of 5 by from Excellent serum/oil This is a classic product by now, and for a good reason. This oil moisturizes well, makes hair shiny and glossy without making it greasy or weighed down. It can be used on damp or dry hair equally well, or, if you'd like, as a mask. It protects hair nicely, and with time hair feels and looks healthier. The scent is nice and isn't owerpowering. This is definitely worth the price over cheaper oils, as you don't need to use too much of this oil to get great results- one or two pumps is enough for long thick hair, and hair becomes significantly better over time.

Rated 5 out of 5 by from Makes my hair PERFECT!! I've been using this every day for years before I blow my hair dry. My local salon advised me this is being discontinued so I looked here and found it. All I can say is that I truly hope this product isn't being replaced. I have VERY fine bleached hair but this oil is all I can use to get a smooth and light blow out. I've tried the other oils and they are too heavy. I ALWAYS come back to this one. The ingredients in this bottle WORK. I can't be the only one that would be devastated if this was no longer available. Please Kerastase KEEP THIS!!!

Rated 5 out of 5 by from Can't believe the results I have thick, curly, color treated hair. Used Nectar Thermique for years with so so results, switched to Keratine Thermique with slightly better. Saw Oleo Relax reviews on the website and decided to try it. I LOVE it! I only shampoo my hair once a week, daily use just a conditioner for 'cleaning'. Tried 2 pumps of Oleo relax after towel dry and before blow drying. No greasy feel, and the shine and silkiness is something I have never had before. I am thrilled with this product.

Rated 5 out of 5 by from Spectacular! I mix two pumps of Oleo-Relax serum with an almond size dallop of Keratine Thermique and apply to towel dried hair before styling (blow dry followed by flat iron). I have shoulder length layered hair that is thick, wavy, frizzy, and unmanageable, but this product transforms it to sleek and silky with lots of movement. I finish up my style with a hazelnut-sized dab of Touche Perfection on the ends. My hair is shiny, soft, and looks great for days.

Rated 5 out of 5 by from Amazing Product! Oleo-Relax is the most amazing product for humidity. I have fine short hair that used to be straight, and now that gray has worked it's way in and I have to color it, I get some waviness. When we travel or during humid months in the US, this is the ONLY product that keeps my hair from frizzing up and becoming a disaster of weird waves! Love it, can't live without having some on hand. Never feels oily, always smoothing, and adds shine!!
