I was told that I did not have enough donor hair, what can I do?

I am not sure why you don’t have enough donor hair. I will assume that you had already exhausted your donor area and now want more hair or more fullness. This can be achieved with beard hair but it may have a different characteristic than your scalp hair.  Body hair is a poor choice as it has less quality.  I recommend Scalp MicroPigmentation as a good alternative for more fullness.
