See an image that represents neaxtlahualli in the Visual Lexicon of Aztec Hieroglyphs, ed. Stephanie Wood (Eugene, Ore.: Wired Humanities, 2020-present).
"iztaian moquetza, iztaian actica, iztacatia ycaia, iztazticac, vel panj qujquetza yn jneaxtlaoal, yn jaxtlacujl," = "She appeared in white, garbed in white, standing white, pure white. Her womanly hairdress rose up."
Florentine Codex, Book, 1 p. 11. Anderson and Dibble translation.
neaxtlahualli = "It was the standard coiffure for adult women and consisted of two horn-like tufts created by dividing long hair in the middle. The hair was bound with a cord, and folded up so as to leave the bulk of the hair resting on the nape of the neck, with the two ends secured at the top of the head."
From the verb axtlahua = rodear ala cabeça los cabellos de muger, componiéndolos.
