You can only achieve a shade like this on pre-lightened hair. We suggest going to a professional to lighten your strands to the level where it can be stained with a vivid semi-permanent.
If you’re looking for an aqua semi-permanent, try ion Color Brilliance Aqua Semi Permanent Hair Color. Leave the shade on for no less than one hour to actually stain your hair.
When conditioning your color-treated hair, always add in a little of your hair color to help refreshen the shade and keep it vibrant.
To avoid fading your aqua shade, make sure to avoid using clarifying shampoos or rinsing with hot water. Keep it warm and cool to close the cuticle.
