Hair Length Needed to Cover a Donor Scar?

Hello Dr

I was just wondering about donor scars. How high up is the donor area on the back of the scalp? Also in your opinion how long does the remaining hair usually need to grow to get a good cover-up over the scar? I prefer to wear my hair short but i was just curious to know what the norm is for most patients that go through the HT surgery.
Thanks

The donor area starts at the base of the skull (feel the prominent bone on the bottom of the skull) and go up a distance of 2.5-3 inches high. That is the donor area (see Norwood 7 art at right).

Scars from strip surgery vary in width. On average about 95% of patients will have a less than a 3mm high scar after one procedure and less than a 6mm high scar after the second procedure. Scarring varies and I see many patients who keep a very small scar (under 3 mm) for as many as 3 procedures. Likewise, some patients will stretch their scars more than others, and the scar could be 1cm high in the rare case. The wider the scar, the longer the hair has to be to cover it. Generally, the width of the scar (height) will require almost twice the hair length to cover it well, but that depends upon the hair thickness and the color / contrast between hair and skin color. On occasion, there is no significant visible scar in strip surgery and this is even more common when a trichophytic closure is used to close the donor area. In these patients, the scalp hair length can be 2-3mm long without showing anything. Having the FUE technique used will change the visible scar risk radically.
