Q: Can you give me an idea of the average width of a donor strip, i.e. the actual width taken from the back of your scalp for a hair transplant? — A.E., Fort Lee, N.J.
A: The average donor strip is 1cm wide, although this will vary depending on the patient’s scalp laxity, density, and the number of grafts desired for the hair restoration.
The length also depends on the number of grafts needed. We average 90-100 follicular unit grafts per cm2 of donor tissue (that is the density of follicular units in an average person).
A 2,000 graft procedure, for example, would require a donor strip 22 cm long and 1cm wide. A 2,500 graft session would be 1.2 cm wide and 23 cm long.
