Does damaged hair from dermarolling grow back? (photos)

Most males with such a short duration of treatment will experience a return to prior levels of hair density within 6-8 months. However, not all. I would estimate that 80 % of males with AGA at baseline with severe scalp traumatic injury (bleeding, prolonged erythema) will feel like they are back to how things were after 6 months but 15-20 % won’t. A small proportion in my experience might even feel things looks better by 6-9 months but that is a very low probability. The chance of regrowth depends on several factors including 1) how fast was the hair loss before starting dermarolling? 2) what other treatments are used right now? 3) how long has the patient had hair loss? 4) what is the age of the patient? 5) were other treatments tried in the past and did not work? 6) does the patient have any other conditions right now like psoriasis, seborrheic dermatitis, telogen effluvium, scarring alopecia? All in all such a short duration of scalp injury usually has minimal long term outcome. However that is not the case for everyone so be sure to speak with an expert. There are many individual factors that influence regrowth. The use of other evidence based hair loss type treatments could potentially have positive effects on the entire situation. Without treatment at all, male balding is always progressive so there most certainly will be more hair loss in the future without any kind of treatment (if the individual has confirmed androgenetic alopecia). But the short term response of the scalp to a traumatic series of dermarolling sessions is usually quite favourable. Be sure to speak with your doctors.
