GK 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 GK Hair products as well as your natural hair texture. The GK Hair treatments are progressive, so, with each treatment your hair will continue to improve over time. To answer the question, no, given the maintenance, the results of the GK Hair Hair Taming system will last up to 5 months.
