There are many different ways to dye hair, and each method uses different chemicals. Some of the most common chemicals used to dye hair include hydrogen peroxide, ammonia, and lead acetate.
Hydrogen peroxide is a common bleaching agent that is used to lighten hair. It is a colorless gas that is released when a compound called peroxides decomposes. Ammonia is a colorless gas that is used to open the hair cuticle so that the dye can be absorbed. It is also used to make the dye permanent.

All of these chemicals can be dangerous if they are not used correctly. Hydrogen peroxide can cause skin irritation and ammonia can cause nausea and vomiting. Lead acetate can cause brain damage and kidney damage.
