Will hold any hair thickness X-thick holds tousled and loose fine hair... beautiful, translucent, very very comfortable! Yes I said Fine hair, try 2 for X-longs. Psst, the sparklies come off only if you want them to, the clean clear rubberized glue that holds the stones on so there is no hair-snagging,comes off clean (just pick it) if you really want a plain version ...hee hee:-)
