I believe if you leave an area about half an inch to an inch they would stay in the hair.
I love the concept of the rollers, easy to use, love the feel of them, however they won't stay in my hair. I suggest you leave an opening somewhere for the hair to tuck into after they are rolled up completely because they fall out because there's nowhere for the strands of hair to stay closest to the scalp.
