BRAZILIAN STRAIGHTENING KERATIN from Kativa, a batch with everything you need to achieve a professional straightening of up to 10 weeks duration. It includes all the products necessary to achieve the treatment as well as a step-by-step guide for optimal results. Suitable for all hair types.
It doesn't have a strong smell, also it's not a product that straightens the first time, my hair was chemical free for over 1 year, but it reduces the volume a lot. You need to use flat iron later to stay smooth.
Despite following the instructions meticulously, my daughter's straightening has not lasted more than a week. I even bought the post straightening products .. for nothing. Buy it only if you want to spend money and two hours of your life, hairdryer and iron in hand, for nothing.
I was watching several tutorials, the truth is that it does not leave your hair completely straight without body. It took about 4 hours but I left it with a fall, some waves and docile ... After more than a week I have no evidence that it has damaged me in any way. So I recommend it, for those people who want to tame their hair a bit because it takes on volume and does not have defined curls.
