Brazilian hair straightening treatments (also called Brazilian Keratin Treatment, BKT, Brazilian Blowout, Escova Progressiva, Keratin Cure or Keratin Straightening) are a method of temporarily straightening hair by sealing a liquid keratin and a preservative solution into the hair.Brazilian hair straightening treatments eliminate frizz, straighten the hair and last about three months. These keratin-based treatments are performed on all types of chemically-treated (bleached, hi-lights, coloured, permed, relaxed or previously straightened) and virgin hair. The technique of the application is similar to the Japanese Yuko System in the way that heated flat irons are used to close the product into the hair cuticle.
|These treatments aim to straighten curls and waves and to reduce frizz. The treatments do not guarantee completely straight hair, although if performed correctly they can reduce between 50 and 80 percent of the curl depending on the original hair texture. Treatments last around 10–12 weeks and repeating the treatment every few months will allow for treatment of new growth.|
