Jet Black Hair Coloring Tuts! For my thick hair I used: (2) Hair Coloring in 2.0 Black (2) 6% Oxidizer (3) Superflex Pag malipis ang hair kahit 1 color, 1 oxidizer and 1 superflex is enough na. Nagdagdag lang me ng superflex para less damage and mas smooth #bremodhaircolor #diyhairdye #jetblackhair
