Keratin hair treatments smooth out and straighten wavy or curly hair. They’re very popular, but these treatments rely on formaldehyde to tame the frizz. Keratin treatments lock the chains of keratin proteins into a straight line, which leaves your hair nice and straight once the treatment is complete.
How does the Keratin Therapy work?
Keratin treatments usually take 2 hours or longer, depending on the length and thickness of your hair. You may not be able to wash your hair for up to 3 days. It is very important that you switch to a sulfate-free shampoo and to avoid sprays designed to create beachy waves. Products that contain sulfates or salt can counteract the frizz-free look the keratin treatment provides and shorten lifespan. The treatment can last up to 3-5 months, depending on lifestyle and maintenance, provided the client follows all after care instructions.
