Hey Coopman,Thanks! It's important to make the client understand the limitations of SMP with scar work. The scar will always be there, what we can do with SMP is create an illusion that tricks the eye so it doesn't immediately jump at someone. They'd have to scrutinize the scalp for a bit. We also recommend doing a test patch first as scar tissue can be unpredictable with how the pigment takes and holds.
