Can you add a coloring booster to hair bleach at the same time?

It's generally not recommended to add a coloring booster to hair bleach at the same time, as mixing these products can alter the chemical reactions needed for effective bleaching. Bleach is designed to lift color, while a coloring booster is meant to deposit color. If you want to achieve both effects, it's best to bleach your hair first, rinse, and then apply the coloring booster afterward. Always follow product instructions and consider consulting a professional for the best results.
