Also known as the Brazilian Keratin Hair treatment, this is a semi-permanent process for those clients who have curly, wavy, or frizzy hair and do not want to opt for the pin straight look. Such a hair treatment retains the body of the hair, but makes the hair more manageable, healthy and smooth. Products and techniques for Keratin hair treatment include Brazilian hair straightening, Brazilian blow out, Keratin complex smoothing, Therapy by Coppola, and Global keratin complex. This treatment lasts up to 2-3 months depending on the hair texture and it takes about 2-3 hours to complete the hair treatment. Keratin hair treatment can also be done on colored hair.
