Did you know you can colour over top of a fill formula without rinsing in between?!?! Something I like to do for my red heads is fill my guest with a demi permanent colour in this case I filled with @schwarzkopfcan 7-77 & 9-7 equal parts & 6 vol! Then without rinsing I immediately apply her root colour! I used @schwarzkopfcan 120g 8-77 & 60g 0-77 with 20 vol! Once her roots where applied I then when straight in with her next formula which I applied from her roots to ends over top of that previous Demi colour!! I used The same formula as my root colour for this! Let me know have you ever done this before?!?! 👇🏼 #schwarzkopf #schwarzkopfcan #igoraroyal #behindthechair #beautylaunchpad #yychair #hairpainters
