* Keratin Bonding: The keratin solution applied during the treatment needs time to penetrate the hair shaft and bond to the existing keratin proteins. Washing the hair too soon can disrupt this bonding process and prevent the treatment from fully taking effect.
* Disrupting the New Hair Shape: The treatment process involves straightening or smoothing the hair. Washing the hair too soon can cause the hair to revert to its original shape or texture, negating the effects of the treatment.
* Preservation of the Coating: The keratin treatment creates a protective coating on the hair. This coating needs time to fully set and harden. Washing the hair before this happens can weaken or remove the coating, reducing the longevity of the treatment.
* Avoiding Sulfate and Sodium Chloride: Most GK keratin treatments require the use of sulfate-free and sodium chloride-free shampoos and conditioners after the waiting period. Using regular shampoos during the initial waiting period could strip the keratin from the hair.
The specific waiting time varies depending on the GK product used and the stylist's instructions. It's crucial to follow the guidelines provided by your stylist to ensure the best possible results from your keratin treatment.
