I agree with most of this post. However, if your hair is long enough on the sides/back that a girl can run her hands through it, there's no way she would notice a scar if she didn't know to look for it. Different story with a #1 or 2 clip on the sides/back, but then there's really no hair to run hands through.
More importantly, l think the biggest difference between FUE vs FUT is the yield of donor hair. Someone with a high NW, thin donor hair and contrasting skin tone/ hair color will likely benefit much more from FUT.
