Pre teens color their hair at home. LF8F twins Jayse and Gypsy get their hair dyed by Raynne in return for the girls appearing in Halloween makeup tutorials for the LetItRaynne channel. Jayse goes blonde on top, and Gypsy gets a blonde streak - which you ually dont notice when her hair is dry because she already started off blonde. Jayses goal was to have hair like Markiplier but public schools in Queensland dont allow students to dye their hair, so hes settled for something a bit more Tyler Oakley. But we will do the full Markiplier hair if he doesnt change his mind before Christmas.\rbr\rbrHow old should you be to dye your hair? Wed love to hear your thoughts, but for the record I completely approve of tweens and teens wanting to assert individuality in harmless things like fashion. It irritates me no end when adults create peer pressure through school uniforms and the like, and then insist on being surprised when kids find it hard to resist peer pressure.
