I want this mans stubble to cover up my acne scars. They are very shallow but cover an extensive area. I have tried acne scar removal and it worked to a degree, but I don't see myself getting anymore of an improvement to satisfy myself. 1. How many grafts would I need for each side to achieve this? 2. I eventually want to get a full hair transplant when I'm older, so I need the hair on my head for this, I will always keep my neckbeard shaved, can I use this hair?
