The tassi is a wide gathered head band that you put over your head and then pull up and it holds your hair loosely between the two elastic bands (it's not flat and tight like the wide head bands). The material is gathered only at the two elastic bands. It doesn't flatten your hair and holds it securely off your face. I stocked up on them when they were available (and when I found at TJMaxx).
If my dog doesn't like you, neither do I.
