Brazilian Keratin Treatment is a method of temporarily straightening hair by sealing the hair with a liquid keratin and a preservative solution with a flat iron.
The Brazilian Keratin Treatment is a long-term blow dry for hair that lasts about three months. Pioneered in Brazil, the Brazilian Keratin Treatment is performed on all types of chemically-treated hair (bleached, hi-lights, coloured, permed, relaxed or previously straightened). The technique of the application is similar to the Japanese Yuko System in the way that the straightening irons are used to close the product into the hair cuticle.
The system aims to eliminate frizz, unruly curls and waves. The system does not guarantee completely straight hair. It can relax between 50 and 80 percent of the curl depending on texture, if done correctly. Treatments last around 10–12 weeks and repeating the treatment every few months will allow re-treatment of the new growth. The treatment does not allow one to wash the hair for at least 48-72 hours, pick it up with any hair clip, pony tail or locate the hair behind the ears.
