Blondes Parade Weekend, Riga, Latvia

Blond or fair-hair, is a hair color characterized by low levels of the dark pigment eumelanin. The resultant visible hue depends on various factors, but always has some sort of yellowish color. The color can be from the very pale blond (caused by a patchy, scarce distribution of pigment) to reddish "strawberry" blond colors or golden-brownish blond colors (the latter with more eumelanin).
From the German for flax or hemp touw , the expression tow head literally means someone flaxen haired. Other variations are towhead or toe head, the latter being a misspelling that does not relate to the word origin.
Writers of English either use the spellings interchangeably or continue to distinguish between the masculine blond and the feminine blonde; and, as such, it is one of the few adjectives in English with separate masculine and feminine forms, at least in written language. Each of the two forms. American Heritage's Book of English Usage propounds that this particular use of the term is an example of a "sexist stereotype [in] that women are primarily defined by their physical characteristics." (Another hair color word of French origin, brunet(te), also functions in the same way in orthodox English.)
