Can localized hair loss be restored?

Whether localized alopecia can be restored depends on the specific situation:

if localized alopecia is caused by bad hair combing habits, hair pulling, etc., and the health of the scalp is good, the size of the hair follicles is normal, in addition to eliminating the cause, pay attention to hair maintenance, and the condition may recover. If localized alopecia is caused by high androgen levels, infection, scalp trauma, autoimmune diseases, etc., and hair follicles become smaller, or necrotic, scalp scars form, hair loss areas may not grow hair again, localized alopecia can not return to normal.
