Colorful hair speaks more about beauty. Now it becomes popular and people are dyeing their hair to make it different. Dyeing hair with natural products is good for health while dyeing with chemicals is harmful. Researches have found that dyeing hair with chemicals can make people have cancer.
　　Lead(铅)is very harmful for the human body and it is used in most hair dyes. Since the base of hair is the scalp(头皮)，you may have allergic reaction(过敏反应).

? It is better to apply hair dye for a few minutes. If you leave your hair with dye, longer than the necessary time，then you may get some skin problems.

hands.
? After applying hair dye it is important to wash your hair with water.
