Alopecia with Scar
This type of alopecia will not respond to microneedling. Please see an expert to evaluate you. Best, Dr. Emer.
You likely have a primary scarring alopecia (central centrifugal cicatricial alopecia) along with evidence of traction alopecia too.
Microneedling will not help you.
See a dermatologist for biopsy and guidance on treatment to halt further loss. Regrowth is not likely.
By using a micro-roller what you do is produce multiple small wounds to the scalp. The theory is that as these wounds heal, hair loss returns. It makes no sense at all
