Nutree ProfessionalBrazilian Keratin Hair Treatment One Step Amazonliss Protein Hair Treatment Formaldehyde Free Hair Strengthening Alisado Brasileño Keratina Brasileña (One Step Keratin 16.9 Fl Oz)

I have been using this for 3 years and it is wonderful. I have curly frizzy-prone hair. I use this every 8 weeks. It reduces my curl but more importantly, keeps it frizz-free regardless of humidity levels. If you have color in your hair, it will remove some or turn it more brassy depending on the color. It is a keratin treatment- that is expected. So, color your hair after this treatment, not before. Hair comes out a bit dry and stiff after application. Once you wash it out, it will be nice and soft and you will enjoy frizz-free hair for several weeks. This protects my hair and allows me to blow it out with every wash, with beautiful results. Overall, highly recommend.

I have extremely frizzy curly hair that is totally out of control and I always have to wear it up or tied back after I blow dry it. I tried this just to see if it would help and OMG, it worked awesome for me!! Just look at my before and after pix!!! I waited a week and washed it and was able to blow it out and style in half a the time. My hair is not as big and puffy now and I can actually put a brush through it once it’s dried. I am in love with this stuff and didn’t realize that my hair needed protein, magic!!! 😊

My hair feels soft and smooth. When I was putting it on, there were no fumes or bad smells. I really do recommend it.

Me encanto!! El pelo quedo divino, y el producto es muy suave, no larga mucho olor y no me hizo arder los ojos! Lo recomiendo 100%

Great product, results was amazing
