Signs of healing of patchy baldness are that the hair at the edge of the hair loss area is no longer loose and new hair grows out. Patchy baldness can be caused by immune abnormalities, heredity and other factors, and is mainly manifested by localized patches of hair loss with clear boundaries. When baldness is cured, no new hair loss area will appear, and the hair at the edge of the hair loss area is no longer loose, and most patients will no longer experience hair loss. As the condition improves, new hairs will gradually grow in the alopecia areata, which are initially thin, soft and light-colored, and then gradually become thicker and deeper in color with the development of time, and finally become indistinguishable from normal hairs. If the above symptoms occur, it can be considered that baldness is beginning to recover, and it is recommended to go to a regular hospital to consult a doctor to clarify the relevant matters.
