Hair comes in many different lengths, styles, colors, and textures.
Normally, hair goes through a regular growth cycle. During the anagen phase, which lasts two to six years or longer, the hair grows. During the telogen phase, which lasts about three months, the hair rests. At the end of the telogen phase, the hair falls out and is replaced by new hair.The average person loses about 100 hairs each day. Hair loss also can have other causes, including drugs or disease.
