Ammonia-based products should not be mixed with bleach in hair coloring due to the chemical reaction that occurs when these two substances are combined. When ammonia is mixed with bleach, it can create harmful gases, such as chloramine, which can irritate the respiratory system and cause serious health issues.

In hair coloring, both ammonia and bleach serve specific roles; ammonia opens up the hair cuticle to allow color to penetrate, while bleach decolorizes the hair. However, combining the two can compromise the intended effects and safety of the procedure.

Water-based, alcohol-based, and oil-based products, while they each have their uses in hair care and coloring, do not produce the same dangerous chemical reactions when mixed with bleach. Thus, it is crucial to avoid mixing ammonia-based products with bleach to ensure both safety and the effectiveness of the hair coloring process.
