What Is the Black Material that Appears on the Skin After Treatment?
It can be identified as the remnants of a club hair. This occurs when a hair is treated in the later stages of telogen with an early anagen hair already growing beneath it. If both hairs are successfully treated, the anagen hair will appear at the skin surface days later. There is also the possibility of hair breakage during removal. This will leave the thick root portion in the follicle. It will appear on the surface a few days to a week after treatment.
