justok [SEP] i will say these are just ok i have really thick hair so regular hair ties do not work wrapped twice because the weight just pulls them down and out i first have to stretch out a hair tie so i can wrap it times without it snapping this usually means my ponytail is nice and tight and it does not budge but it also means i have headaches the first or times i used it it help pretty wellbut for lounging around the house i cannot imagine trying to do any kind of rigorous activity with this in or it would fall right down after the first use it did stretch out but after putting it in hot water it shrank back down to it is tiny self after the time trying to shrink it it only goes down to the size of a normal hair tiewhich also means it does not hold as tight anymore i do like wearing them for around the house though because it does hold up the hair and does not give me a headache i have not noticed the crease in my hair and it also does not leave marks on my wrists from being too tight so all in all they are ok
