My hair: very dry, coarse, thick, wavy, colored (from grey).
How this product works on it: like a good hair perfume.
What it does not do: anything a hair serum is supposed to do.
What I recommend and buy instead: Joico K-Pak Color Therapy Oil or Matrix Biolage Oil.
If I wanted to stick with Kerastase I would buy instead: Elixir Ultime (original, golden)

I see so many people compared this oleo relax serum with elixir ultime hair oil, which I think a totally different product. I bought both products though (which cost a lot x'D) First of all, this is a serum not a hair oil, therefore, of course, works differently. I have fine, natural dark brown, straight, virgin, bra strap-long hair, quite oily on the roots, and no split ends..
my hair is not frizzy yet I love to try hair products, lol.
This serum is made for people with frizzy and unmanageable hair, I applied this serum on damp hair, and it makes my hair really soft and frizzy-less, it also did not weight my hair down. however, this product makes my hair color slightly lighter (idk why) and my hair becomes a bit more oily on the night.
The elixir ultime hair oil in gold, tend to give more moisture to my hair (of course more oily) I love this product more as it gives the soft glossy healthy look, i use this right after styling my hair with a straightener, remember, apply only adequate amount, as if you apply more, your hair will be weighed down and terribly oily.

I was super excited to try this serum since I haver dry, thick and super frizzy hair... well... this made it worse..it's like it was supposed to do the opposite. It didn't calm my hair down, it didn't smooth, and it made even MORE frizzier...
I would never purchase this again I have MUCH MUCH better magical results with the Kerastase - Elixir Ultime serum.
Save money on this oleo relax serum and get the elixir ultime!!

The best hair serum I ever used! Better than any oil I used :macadamia,agadir,mythic oil,orofluido,elixir ultime... Hair is really silky,frizz free,shiny and bouncy :) I do not like the smell,it really floral and that makes me nauseous.I hate the fact that on the pump you do not have any arrows or marks indicating that you closed it.I wasted a lot of product because I didn't know it was still open.That's really annoying.

you really are wasting your money if you buy this , though it may work , you can buy a much less expensive product and get the same results and btw it's made by loreal so what do you really think is going on , i'd suggest skinny serum by paul mitchell or even loreals products you can buy at Walmart or Target , just because you pay more doesn't always mean it's better , I have been a hair stylist for almost 20 years and I do know what I am talking about

I'm on the fence about this serum. I have long, thick curly hair that I often blowout or have blown out, and I used to mix this together with Nectar Thermique prior to blowing dry. I found that my blowouts didn't last long, and my hair would get frizzy rather quickly. I switched to Moroccan Oil and it works like a charm.

That said, I do like this serum as a finishing touch to control fly-aways and adds shine, and it works very well for those purposes. It also smells fantastic. Not great for keeping my thick hair straight, but awesome for that glossy finish.

I was really excited to try this serum, but personally I found it to be over-rated. It didn't do anything more for my hair than a basic serum would. It also made it very flyaway. I used varying amounts after washing my hair. It was best when using a very tiny, tiny bit, but still not amazing. It worked better as a pre-wash oil, but no better than jojoba oil which is a fraction of the price.

I tried to like it. I used it again and again in different ways, but it just did not suit my hair. I would recommend trying to get a sample before buying the full price bottle as it is very expensive.

I've tried many other hair serum for the past 10 years and I always come back to this one. It makes my hair very soft.

i love the fact that this serum is so lightweight and you dont have to worry about over applying because it does not weigh my hair down.
I think it is a bit expensive for a serum, but it does make my hair looks shinier. As for frizz, i dont think it does a good job becuase my hair becomes frizzy again after the next day. Too bad this serum cannot be apply on dry hair.
Don think i will repurchase because of the price. Love the packaging though, small and convennient.

I've had a bottle of this for over a year, and I use it every now and then. The smell is absolutely beautiful and I think that's one of its best features. It makes my hair feel soft, but I don't really notice whether it controls frizz or not. Also I have long thick hair and find it can make my hair a tad greasy, but most serums have this effect. I would buy again because of the amazing smell and a bottle lasts a long long time. Be careful with the packaging of this serum as I find it leaks , so always have it standing upright
