ㅤLast Friday my mom decided to color his hair.She studied with all the hair products at the drugstore.The color she choose came in a box which had a picture of a woman that hair color looked just perfect.Mom was sure same color would look great on her.She put the new color on her hair or sat still for 30 minutes，just as the directions saying.However，instead of the brownish red hair she had hoped for，she final got purple hair.She went right into the shower to washing it，but it was no use.At least one thing proved truth：the color wouldn't wash out.
