In a bowl, mix white conditioner (any old conditioner will do, as long as it's colorless) with just a tiny bit of purple vegetable dye, or of both blue and pink vegetable dyes, such as Manic Panic or Special Effects. Then, overtime, as I wash my hair, it gradually fades to a pastel. This article was co-authored by our trained team of editors and researchers who validated it for accuracy and comprehensiveness. If you need more add more colour, if its too dark add more conditioner. The gold standards for fun hair colors are Manic Panic and Special Effects. Only mix conditioner with semi-permanent shades.
