Good Dye Young Steal My Sunshine Semi-Permanent Hair Dye A trippy, acidic yellow that’ll make a glowstick jealous. This shade is even neon under blacklight! Botanically Infused with Natural Sunflower Extract. Semi-permanent dyes will show the truest color on pre-lightened hair, levels 8 - 10. Semi-perm is a thick, conditioning formula, no need to mix with a conditioner. Color payoff will vary based how much hair is lightened as well as on the porosity of the hair and underlying hair chemistry. We recommend a hair strand test to determine color payoff. Please note: The color out of the tube is a golden yellow. After a couple of washes, the color turns into the Steal My Sunshine you love.
