Choose a small and inconspicuous patch of hair to be tested. Comb through a small amount of the Step 1 solution. Use the knot test (this site has a great explanation and videos on how to do it:
http://www.conairpro.com/ti/how_to.html) to determine how long it needs to be processed. Wash out the solution and flat iron. Comb through a small amount of the Step 2 solution, let rest for 5 minutes, wash out, and condition.
If you have problems with breakage or are unsatisfied with the hair after this test patch is completed, DO NOT process the rest of your hair.
Make sure to record your processing time!!
