There are numerous ways to categorize hair loss. One must first examine the scalp to determine if the hair loss is due to the physical destruction and loss of hair follicles (scarring or cicatricial alopecia). If the scalp appears perfectly normal with plenty of empty hair follicles, this is called non-scarring hair loss. On the other hand, cicatricial alopecia permanently destroys the follicles. Non-scarring hair loss also happens in situations where there is physical or chemical damage to the hair shaft, resulting in breakage. Occasionally, it may be necessary to do a biopsy of the scalp to distinguish these conditions. Sometimes, a physician may pull a hair to examine the appearance of the hair shaft as well as the percentage of growing hairs (anagen phase). This article will concentrate on the non-scarring types of hair loss.
Tissue expansion. In this procedure, a material called a tissue expander is inserted under portions of the scalp with hair. Saline water is injected for six to eight weeks in order to expand or stretch this portion of hair-bearing skin. The bags are eventually removed and the expanded hair-bearing skin is cut away and moved to the adjacent bald area. This is typically used to address hair loss as a result of burns or injuries on the scalp.
