In cosmetology they dye hair. Many people decide to do different things like a balayage. That is a different way to dye your hair because you go from dark to light color. When you dye a persons hair you have to be careful to put the right chemicals,right forms and measurements it ask you for in the box. If not they can have a reaction or something bad could happen to their hair. For example if you leave it to long of time it might cause the hair to get ugly, it could look mistreated or maybe i could get a different color than what the person ask you for.
