1. Start by sectioning hair in the back into 1/2-inch subsections in a bricklayer pattern. Tease hair, apply Formula A and place in foils.
2. Continue this step until you reach the front. Take very fine, diagonal sections going back and apply Formula B in a heavy weaving pattern. Do not tease the hair at all.
Pro Tip: After seven foils switch back to weaving and teasing each section to keep dimension at the roots.
3. Once the hair has processed to a place yellow, wash and apply Olaplex No.2. Let sit for 15 minutes and rinse out.
4. Section hair at the hairline and apply Formula C at the roots only.
5. Apply Formula D to the rest of the hair, let process for 15 minutes and rinse.
