Keratin Smoothing Hair Treatments do not permanently change the structure of the hair. Instead, they rearrange the hair molecules to reduce the natural curl pattern. You can expect the results to last for 3-5 months depending on the home care regimen with approved hair products as well as your natural hair texture. The treatments are progressive, so, with each treatment your hair will continue to improve over time.
We recommend waiting two days to wash hair because it takes 48 hours for the treatment to form a stronger bond with the hair cortex. If the hair is washed right after the treatment, some or most of the treatment may get washed out and the results may not last as long as desired.
For the first 48 hours, the hair should not be exposed to water or steam or put in a bun/ponytail. After that, it should be shampooed and conditioned with a sulfate free shampoo and conditioner.
While there aren’t any known adverse effects, pregnant/nursing women should consult a physician prior to any type of hair treatment.
