So it's important that your expectations are realistic and that you exercise patience while you explore your options. Before we discuss the reasons for hair loss, let's do a quick review of how hair works. This should help our understanding when we begin to look at the different transplantation procedures. Typical mammalian hair consists of the shaft , protruding above the skin, and the root , which is sunk in a follicle , or pit, beneath the skin surface. Except for a few growing cells at the base of the root, the hair is dead tissue and is composed of keratin and related proteins.
Human hair is formed by rapid divisions of cells at the base of the follicle.
As the cells are pushed upward from the follicle's base, they harden and undergo pigmentation. The hair on our scalps and in our eyebrows and eyelashes are different from other bodily hairs. The hair on our heads grows a healthy .5 inch per month, and long scalp hairs have an average life of 3 to 5 years. Inc. All rights reserved.
