This product is the reason I had to cut my hair off! After close to a year since having used it my hair is still not right! Upon putting the product on my hair I knew I had made a horrible mistake! My hair instantly began to almost melt. It broke entire sections..it was truly the worst hair experience of my life!

Tried this on my sons thick, big cult hair. He usually flat irons it but we decided to give this a shot. Horrible results! It left his hair dry, poofy, and frizzy!

Update: Loreal (owns Garnier) has had a product liability lawsuit filed against them due to this product. I do not know the final outcome

Wow i was going to try this to make my hair stay pin straight i have healthy non color treated hair and non processed hair. I am going to return this i can't thank you enough for saving my hair :)

This is def the worst product I have ever used! It is funny how some reviewers are repeating what the box states...It says to wait 2 weeks after coloring your hair, then elsewhere it says that if your hair is treated in any way, to not use it! It does no good to repeat the same bs twice, it doesn't make sense the 2nd time either.
I used this on my hair a few months ago which happened to be just before my wedding. For the first time ever, the ends of my hair were just breaking off. I would brush my hair and have all these short pieces of hair all over my clothes....and this is still happening, even after a trim. My hair became dry and thin as well. Now it is almost back to normal but the people producing this stuff should spend more energy on taking it off the market and less on writing phoney reviews that just sound ridiculous....ps: it does not make it more believable to write "like" in a review to make it sound as if as 18 year old wrote it. Like, you know what I mean??
DO NOT USE THIS PRODUCT

I used this product on my very healthy hair and it completely damaged it INSTANTLY. My hair completely changed after using this product. I tried so many treatments for a few weeks to try to restore my hair but nothing worked. So yesterday I had to get 7 inches cut off because of what this product did to my hair! I am completely disappointed with Garnier and I will honestly think TWICE before I buy another product of theirs.

This stuff is terrible. Did this treatment a year ago and completely ruined the ends of my hair, turned the ends into a frizzy kinky mess that I couldn't even get to straighten and look normal. My ends began to fall off.. I was forced to cut a few inches off my hair that was already shoulder length.. My hair is still not the same.. I regret using this so much.. Please be careful using this..

Ok, so first of all, for those of you who have bleached hair, you are not supposed to use it, regardless of how long ago you bleached it. And second of all, it even says in the instructions, that if your hair has been colored/permed you have to wait at least two weeks before using it. And for those who have relaxed or chemically treated you're not supposed to have your hands on this product either. Bottom line: If your hair isn't bleached, permed, chemically treated, relaxed, highlighted/colored, then you can use it straight away. Gosh, people, READ! I bought this product like in January or February and it's amazing. My hair is in suitable condition to use this product, so I went ahead and bought it. I used it the moment I was free to take a shower. The smell of the serum was horrible, but I pretended to tolerate it. Then after towel drying my hair, I applied the cream, and straightened my hair the next day. It did exactly what it promised, and I only had run the flat iron over sections of hair twice. Before, it was like, 5 times, which equals a ton of damage. I would totally buy this product again.

This stuff is horrible! DO NOT USE! I used it before reading reviews and it made my beautiful, thick, long hair extremely dry and thin/stringy. I had to cut some of it off and use a lot of repair treatments in the salon and at home. It's been a year and a half and my hair is still not the same. I can't wait for all of it to grow out. This product really needs to be taken off the market.

Stupid me, bought this without reading the reviews first. I thought I would use this to keep from doing my hair everyday. I washed my hair per the instructions, and put on the gloves. I started to apply the product to the ends and mid sections of my hair. Pretty quickly I noticed the smell, it's really really bad smells like a mixture of rotting eggs and rotting meat. The smell at some point became unbearable, but I continued to apply the 20 minute smooth it serum. As I was applying this stuff I was thinking to myself, I should really read the reviews on MUA first, something doesn't seem right. I've used an at home perm product once, and bleached my hair at home a few times as well. In my experience the worse something smells the more likely it is to damage your hair. So after getting the whole tube of serum in my hair I login to MUA and read the reviews. I start getting scared, the reviews are abysmal. I had serious damage years ago from the aforementioned bleaching at home. It took months for my hair to recover. I ran in the shower and rinsed the crap off, after like 5 minutes. I then applied a large amount of deep conditioner and let it sit for several minutes. So far my hair seems fine.
