If dirty or greasy, please wash the hair and dry completely before starting the next steps.
STEP 1 Apply the product on individual sections, leaving half centimeter from the scalp, using a comb to spread the product thoroughly. Let the product process for 60 minutes on thin or sensitive hair, and for 90 minutes on very curly, thick and resistant hair.
STEP 2 Once the product has processed, rinse 70% of the product from the hair by using only water. Do not use shampoo. (Note: If the hair is very curly, thick or resistant you can achieve better results by removing only 50% of the product).
STEP 3 Blow-dry the hair in small sections.
STEP 4 Flat-iron the hair in thin sections several times (normally 15 times each section). The temperature of the flat iron should be 230ºC (Note: If the hair is sensitive or colored, test the appropriated temperature).
Always use your professional judgment.
