It acts as a hair de-frizzer. It is a revolutionary treatment that softens, shines and straightens the hair whilst making the hair healthy. It penetrates the hair, repairing internal damage and coats it to prevent further damage. It is not a chemical that restructures the hair, but only replenishes, reconditions and protects the hair from water and heat damage, whilst enhancing its natural shine. It also makes the hair very manageable and will require less blow drying time and results will be very good when using a flat iron. This Brazilian treatment does not use strong chemicals to open and close the hair cuticle in an effort to straighten it. It only coats the hair. It does not break the bonds of the hair shaft like straighteners do. Brazilian Treatment is not permanent. It naturally fades out of the hair and wave or curl will come back in a few months. The hair will stay soft, shiny and healthy looking. It contains Keratin, Collagen and Silicones. It contains only 0.2% Formaldehyde.
