Step 2: Test Patch
Heres how you do it:
After about 5 minutes, take your treated strand, and tie it in a loose knot, just tight enough that you cannot see through the middle at all. Then let go. If your hair bounces and you can see through the center of your knot again, then it isn't done yet. Keep the solution in until the knot stays closed even after you let go. For me, this is about 30 to 45 minutes.
Wash out the solution and flat iron. Comb through a small amount of the Step 2 solution, let rest for 5 minutes, wash out, let dry, and check the 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!!
