Directions Rinse out neutralizer, do not dry hair. Apply Curl N' Lock and gently work lather through the hair. Rinse thoroughly. Only one application is necessary. This after perm treatment allows immediate shampooing after neutralizing any permanent wave. It acts as a neutralizer accelerator to instantly complete the neutralizing process that normally takes 24-48 hours. The curl pattern is locked-in and perm odor is eliminated. Clients are left with hair that smells as good as as it looks.
