Kérastase Elixir Ultime - Prime Customer Reviews

The smell is horrendous! It smelled like I had burnt my hair when I hadn't even blow dried that day. It's a cheap repackaged product, stay away!

This product smells great! I have fine hair which goes limp when just about any product is used. Unfortunately, although it smoothed my frizzies, my hair was flat to my head within a few hours. I won't be buying, but I do recommend to people who like or want to try hair oils.

My hair is very oily so the product made me hair look stringy and greasy. I would recommend this product to someone with dry hair.

this was ineffective for me. i have long, bleached, thick coarse hair. it will take a lot more to make me see and feel a difference.

I've been trying to work on how much of this to use and I can't figure out a way to use it that doesn't weigh down my hair. I like Kerastase products but this one is tricky.

I have slightly coarse, slightly wavy hair that needs an oil or silicone based product applied before blow-drying it straight. (Otherwise, my hair has lots of fly-aways and tends to look slightly frizzy). I bought this product hoping it would give my hair a nice gloss, but instead, it left it rather limp. I tried using it several times, using a slightly different amount each time, but did not see a real difference. If you are looking for a product that is nourishing AND adds bounce, I would recommend the Agave Healing Oil Treatment (also sold on the Birchbox site!). I'd like to wrap it up by saying this product *may* work better on a different type of hair - I've seen reviews online with pics of people with stunning results - but for me, I found the Agave product more effective.

The description is correct in stating that this product is " lightweight". I found it too lightweight in the fact that it did not do what I expected an oil to do, smooth split ends and add shine. I am a faithful Moroccan oil user , which although heavier, always smooths my hair, conditions it and smells delicious! This product fell short in all those categories, and has barely any scent. Possibly good for those with fine hair but most people with fine hair stay away from oils. Maybe if the product was cheaper I would have been more satisfied.

This product works ok for smoothing out frizz, but I think Moroccan oil works much better - not planning to purchase this one...

I tried the product included in the BB. I have long curly hair, so the sample was enough for one use, but honestly I think that I would need more than was included to get the full effect. It was okay. I didn't see any major improvement after using it. I have dry curly hair, and this just didn't do the trick for me.

I usually use Moroccan Oil for my extra dry wavy hair and honestly, this didn't even come close. My hair was still extra frizzy even after adding twice the recommended amount. I do, however, live in CO and we have little to no moisture in the air which could have contributed.

But honestly, that wasn't the deal breaker. It smelled awful and chemically, even my boyfriend noticed and asked if I had burned my hair with a flatiron. I tried this, I really did, and I really wanted to like it, but it just didn't work.
