Dear Adam,Since you're only 24 days post-op, you can count on the individual scars left behind by the FUE procedure are going to continue to get smaller and fade for the next 6-8 months. They will be in their final state and size and color at 12 months, or about 11 months from now. Regarding how short to cut your hair, that depends a lot on your hair shaft diameters; the thicker the individual hairs, the shorter you will be able to cut your hair. It differs on a person-to-person basis. I would let it grow out until you can no longer see evidence of the FUE procedure, then when it's as long as you can stand it, go to your hair stylist, and have them go a little bit at a time. Then, you'll reach a point where the FUE work is still visible, and that's where you stop. If you're using a clipper, remember the clipper number. Go one clipper number higher next hair cut. As the next 11 months pass, the area will progressively fade, and you will be able to cut your hair shorter and shorter.
