Flashback to when tie-dye shirts were the hottest trend at Summer camp. We remember stamping everything from t-shirts to trucker caps in the psychedelic pattern. And like most trends from the '90s, tie-dye is back, but this time it's not just reserved for fabrics. The technique can also be used on hair (rainbow mermaids [1] rejoice!).

Rickey Zito and Pravana teamed up to create this awesome how-to video [2]. The color is acheived by sectioning hair off with rubberbands, which leaves a blank space in the pattern. The outcome is dip-dye [3] on steroids! Watch the full tutorial below.
