Hello, I was told by doctors I need about 3000 grafts for FUE. My hair is thin on the front but the balding is general so I need the new grafts to be blended with my existing hair. I like shaving my head to 3mm which I think is equivalent to #1 guard. Will scars in the back of my head will be visible if shaved to 3mm? And more importantly, will the frontal area look natural? Will the new grafts blend well with my existing grafts when I shave to 3 mm ? Is it too risky? Thanks in advance,
