All of the different responses are very interesting.
Natalia: I measured mine from the top of my eyebrows to my hairline and it's...exactly 7 cm! But my hairline shape isn't quite an M, although it does recede at the corners. It's more of an inverted U with square corners, if that makes sense; it doesnt dip down in the middle form an M shape. So I'm surmising I should should for 5 cm when it's all said and done.
Can doctors advance hairlines as much as 2 cm? I'm guessing I'll have to talk to my doctor about advancing it a little less, because I will need a little room for the micrografts.
For those that have had them, how much space does it usually take to cover a hairline advancement scar. If the doctor can advance my scalp at least 1-1.5 cm, is .5-1 cm enough room to fill with micrografts?
Thanks!
