Abstract

Three subjects with virgin African hair combed daily had surprisingly short hair length measurements of 40.1 +/- 14 mm, 60 +/- 10 mm, and 69 +/- 20 mm at 6 months, 1 year, and 3 years after a haircut, respectively. This observation raises the possibility that combing African hair on a daily basis may result in the equivalent of a daily haircut in some people. This observation is based on few participants and will require confirmation in population studies.
