Gas chromatographic analysis of fatty acids of human hair lipids.

Hair lipids pooled according to sex, race and scalp condition have been saponified and the fatty acids up to C22 analyzed by gas chromatography of the esters. The same peaks occurred in each of the chromatograms and aside from rather small fluctuations in a few of the acid levels, no unequivocal differences could be discerned on the basis of the categories investigated.
