KERATIN RESEARCHKeratina Brasilera Tratamiento Capilar con Champú Clarificante, Resultados Profesionales, Alisa y Suaviza el Cabello (Keratina por 120ml)

I had really dried , fine, curly hair with lots of split and dead ends and could never wear it curly because of all the frizz and any styling product would weight it down. I was really tired of that big, puffy , impossible mess on my head . I followed the instructions that came in the package together with the bottle , the whole process took me several hours, mostly bc I had to stop multiple times to attend my toddler daughter or because I needed some air. So I started by washing hair twice with clarifying shampoo, then blow dried my hair, applied the solution (don’t let the solution touch your scalp , it burns), used the fine tooth comb to take the excess of product out of hair , waited between 20-30 minutes before blow drying hair again but this time with the product still on hair. Blow dried and then straighten the hair. Hair is going to be super sticky after blow drying and your brush and comb will look disgusting. If after you’re done straightening your hair still looks sticky you probably need to keep straightening until your hair looks nice and silky. I was hesitating , I didn’t know if leaving it for the full three days or if washing it before that and keep my curls or at least some waves. I washed it 36 hours later with sulfate free shampoo, I thought my hair would look like nice and curly with looser curls or at least wavy ,but nope in those 36 hours my hair went from 3b to plain 1 with some 2a waves on the lower back of my head, and I’m totally fine with it now I won’t have to style my hair unless I’m going out to somewhere special , glad I didn’t wait the full three days or my hair would have turned out to be too straight and with no volume. Now I’m going to need to buy a new shampoo and conditioner because the ones I’ve been using make my new straight hair too oily

I love this product and the fact that nothing has changed. Some products start great then they change the formulas and there goes the product a flop. But this is my 4th bottle and always love the results. Great stuff don’t ever change please. My hair looks smooth and so healthy

This is an excellent product, my hair stayed straight even in high humidity and it was better than the one I had professinally done!

I love when you don't have to pay extra to get the product fast and the product gets to your house super fast! yey!! I always use this product because my hair is waivy and poofy. This product leaves my hair shiny and super straight! I leave it on for 30 minutes and after blow drying and straightening with the flat iron, I leave it in for 3 days, and it always works for me.

I have fine, medium length hair that is naturally very dry and is frizzy and knotty.I've used Brazilian Keratin treatments before at home and had them done in the salon too. However, I was not happy with the results this time. It worked well on the very top of my head, however the rest is still very knotty and frizzy and dry, even after putting lots of deep conditioners in. So I'm really disappointed and don't understand why as my friend who did it followed the instructions perfectly and definitely put enough product in.. and I even kept it in and straight and smooth for 3 days before washing it out. I haven't used any products with salt in or anything either.

Si pudiera no les daría ninguna estrella, la botella venía abierta descaradamente y es sumamente pequeña, no me sirve para nada y pague más de 40 dólares más shipping y ni siquiera hacen reembolso

This is most amazing product that I ever had ! Even after I washed my hair, still looked straight and amazing soft, just few passes with hair straighteners and ready to go! Usually took me an hour and still didn’t feel soft ! This is product for my whole life !

Es un excelente producto, puede que vean que el frasco es pequeño pero bueno son 120 ml no pueden esperar que venga en un botella grande pero es suficiente para usarlo una vez, mi cabello está arriba de la cintura y me alcanzó perfecto. Definitivamente voy a volver a usarlo, sigo teniendo un poco de frizz pero siempre lo tengo liso y usando cualquier aceite el frizz se va.
