Hair transplant on birth mark? (photo)

Assuming your birth mark is a benign one (there are some birth marks that need to be surgically removed due to their potential for transforming into skin cancer), hair can be transplanted safely into it, as a general rule. It looks like most of the birth mark is located in your hair-bearing area, so most of it could be potentially covered by a hair transplant. Of course, I am making some assumptions here. You need a consultation for a full evaluation.

Hello and thank you for your question. I suggest seeing your family doctor or dermatologist in order to determine what is the best solution for you. It's difficult for me to assess by looking at your picture and I don't want to give you false hope or information. Best of luck to you.

Here's a revised version for improved grammar and fluency:
From the photo, I understand that this birthmark could be causing you significant concern and possibly affecting your self-confidence to some extent, which is why you're considering a hair transplant to cover it.
However, a worst-case scenario that you might want to consider is the possibility of the birthmark developing into skin cancer. Having hair above it could make cancer monitoring very challenging.
I would recommend consulting with both a dermatologist and a plastic surgeon to obtain their opinions on this matter, as it is not a typical case. I hope this helps.
