The Brazilian Blow Dry takes between 1 to 2 hours, depending on length, hair condition, and hair thickness. It is NOT meant to be permanent and it DOES require redoing approximately every 2 to 4 months, depending on the individual’s hair type and preferences. Regular treatment helps to blend treated hair with the natural growth of hair. It does NOT use strong chemicals to open and close the hair cuticle in an effort to straighten it. Keratin is a natural substance which comprises 88% of your hair. It penetrates the hair repairing internal damage and coats the hair preventing further damage. The results are soft, shiny, straighter hair. The Brazilian Blow Dry is excellent on all types of chemically treated hair (bleached, hi-­lights, coloured, permed, relaxed or previously straightened). It is excellent for getting rid of curly, frizzy, damaged, unhealthy, dull and mistreated hair. Although often referred to as a straightening treatment, the Brazilian Blow Dry is extremely versatile.
