Marcia recommends to use her Advanced Keratin Treatment, it will loosen your curl pattern, up to 80% it's rinsed out the same day, so it will not last as long .....

To remove the BKT faster, shampoo with a clarifyng shampoo, Marcia's is very alkaline and it's designed to open the cuticle before the BKT so the Keratin can penetrate deeper...by using it after the BKT it will help to remove some of the keratin...another very effective way is to apply a permanent hair color. When you apply a permanent hair color the cuticle is opened to remove/deposit color..this will get rid of most of the keratin.
