The DevaTowel is a microfiber hair towel made for drying curly hair, using a smooth woven fabric instead of the looped terrycloth texture found on standard bath towels, from DevaCurl's curl-care tool line.
Terrycloth's raised loops can catch on the hair cuticle and rough up curls as you dry, creating frizz; the DevaTowel's smoother microfiber surface is gentler on the cuticle while still absorbing excess water, so curls can dry with more definition. The towel measures approximately 39" x 20", is hypoallergenic, and includes a hanging loop for storage between uses.
It's a drying towel rather than a treatment product, so it doesn't add any styling or conditioning benefit on its own - it's meant to be used after applying stylers to wet curls. It can be machine washed, though DevaCurl recommends hanging it to dry rather than tumble drying.
