HOW TO: Foil the back of the head This is my go-to way of foiling the back of the head for a highlighted look! ✨I always start by doing the 9 foil hairline technique! (Video tutorial posted to my grid a few scrolls down) ✨From there, I divide the hair into 2 sections down the center. Starting on one section, take horizontal sections and weave back-to-back foils working up the head. Repeat on opposite side and the foils should line up perfectly at the crown @behindthechair_com #behindthechair #bt
