Final answer:
Oxidate reactions can affect hair color, especially at an alkaline pH. Permanent hair coloring involves the use of an oxidant to oxidize certain compounds in the hair and create larger dye molecules that are locked inside the hair.
Step-by-step explanation:
Oxidate reactions can affect hair color, especially at an alkaline pH. Permanent hair coloring involves the use of an oxidant, which oxidizes certain compounds in the hair, leading to the formation of larger dye molecules that are locked inside the hair. The process of oxidation dyes involves the oxidation of 1,4-diaminobenzene derivative to the quinone state, reaction with a coupler compound, and further oxidation to give the final dye.
