not for fine or thin hair [SEP] the clip provided barley fits around the curler itself so there is nothing to hold the curler to your head prepare for a battle my hair is also too short for this it sits just at my color bone i would say you would easily need hair to your mid back for any chance of this working also this curler is made of thick foam i do not see it being comfortable to sleep with maybe if the foam broke down a little as time went on overall i would not recommend use a robe wrap and save yourself the frustration
