The result is good so far...but the process...OMG I thought I wouldn't make it. The smell was not too bad at first, but when I put keratin on my hair, my eyes and throat burned so badly. The situation got worse when I dried my hair, although I wore 2 masks. The result is good, but I will try to find keratin without formaldehyde for the next time.

Arrived in great condition and in a timely manner. I have never tried this product before, but will within the next few weeks, Hoping it will work well. It would save me alot of money in the future if it does.

The product is absolutely useless . I did everything that was said in instructions very accurate, it took me a lot of time and effort, and after I was done and rinsed it (as was said in the instruction) , the straight hair was gone.. like nothing changed , absolutely waste of money .
