Is it possible to do a hair plantation on a birthmark? (photo)

Hello in Mumbai,Although it is hard to diagnose from the photos alone, this does not look like an ordinary "birthmark".  It may be a "nevus sebaceous", which most usually presents as a hairless, raised area on the scalp, usually at birth.  It can also change its appearance as you grow.  There is a small possibility it can develop into other skin lesions, so you need to have it seen by a dermatologist and have a proper diagnosis made, and perhaps a biopsy.  A small percentage of these can develop into a mild form of skin cancer (a basal cell carcinoma).  Get it checked out first before you even think about a hair transplant.

I would have to examine you to make sure that the birth mark is not vascular. If not, it should take to transplants very well
