23 yr old female (5'6" 120 lbs) the skin on my scalp is very flexible (I can move the skin on my head back & forth as I have a lot of skin on my forehead that I can pinch). I just want my hairline lowered at least an inch. Don't want use of an expander nor grafting just have my hairline lowered a little, how much would that be? I'm referring to the most minimal scarring & incisions which I think is FROST hairline lowering surgery.
