Next, create top knots and secure each diamond section, leaving out the front hairline.

Within your diamond sections, take horizontal, thinly-sliced, back-to-back sections of hair at the beginning of the front hairline and then apply Formula A from the scalp to the ends to prelighten the hair.

Repeat step 1 within each diamond section until the hair reaches the desired Level 10 (leave out the section at the top center of the head). Then, shampoo with BC Bonacure Fibre Force Shampoo and dry the hair.

Apply Formula B to the regrowth. Do not color hair within the original diamond section and on the back of the head.  Process as recommended and place protective foils over the processing base.

On the left prelightened, diamond section on the back side of the head, take thinly-sliced, horizontal sections on a foil and apply Formula C from the scalp to the ends.

Next, repeat step 4 using Formula D and then Formula E.
