leiotrichous is the word for having smooth hair - from the Greek leios: smooth, plus trikhos: hair.

lissotrichous is having straight hair - from the Greek lissos, which, in addition to straight, also means smooth, thus the confusion.

The terms are rare, but still to be found in the vocabulary of some specialists, especially zoologists.

That these terms exist at all is due to the French naturalist Baron Jean Baptise Genevieve Marcellin Bory de Saint-Vincent, who travelled the world at the beginning of the nineteenth century studying plants. He also made a stab at classifying peoples into races. He is now hardly remembered, but in a once-influential book Homo: essai zoologique sur le genre humain, published in Paris in 1827, he attempted to classify humans with straight and wavy hair into the Leiotrichi and those with woolly or tufted hair into the Ulotrichi, with many sub-groups below these headings.
His classification was seriously studied for several decades, being quoted-for example-by both Thomas Henry Huxley and Charles Darwin.

That you for that extremely interesting story. But I can plainly see why Baron Jean Baptise Genevieve Marcellin Bory de Saint-Vincent drifted off into history and long forgotten... who the hell could remember his name.

Oh, I don't know, LC. This is copied directly from, I'd bet, the very same site you got your information. Read all the way down into the second paragraph. Looks like 'smooth' to me:

LEIOTRICHOUS
Having straight hair.
Don't expect to find this word turning up in your newspaper any day soon, as it is now rare to the point of complete disuse. It comes from Greek leios, smooth, plus trikhos, hair.

His classification was seriously studied for several decades, being quoted-for example-by both Thomas Henry Huxley and Charles Darwin. The adjective ulotrichous (Greek oulos, woolly), from his other main category is also rare, but the related lissotrichous, smooth-haired, is still to be found in the vocabulary of some specialists, especially zoologists; this comes from Greek lissos, which also means smooth. A third category is that of wavy-haired or cymotrichous people (from Greek kuma, wave). These last three adjectives have been used to classify types of hair, for example in forensic identification.
