Although it is popular to *say that blonde refers to women and blond to men I think that an examination of usage will show, at best, only a slight tendency towards this convention. In the case of blond hair, it should be noted that the gender of the adjective would be expected to match the gender of the noun hair and not the sex of the person sporting the hair. Haar, the German cognate to the English hair, is neuter and by and large, before the conflation of gender with sex, when we concerned ourselves with such niceties, the gender of English nouns matched the gender of the cognate German noun. I'll report back later when I get my hands on my AS wordhoard.
