This heat reactive temporary hair color is super fun.
Each of the color choices has a base color that changes into the second color when heat from curling/flat irons, blow drying, sun and touch is applied and back to the first color when the hair cools down.
Cool violet to warm pink, lime green to sunny yellow, smokey grey to invisible and tropical peach to invisible.
These colors can be used on natural hair but work best on pre-lightened hair and clip in extensions for repeated use.
