i do not recommend this tape [SEP] i normally use both wefts but decided to try single sided tape for my top two rows of wefts i like that i could use less hair felt less heavy however the tape curled after the first wash days after install and weeks later two wefts slide out what s left behind is messy and sticky i purchased this tape stupidly because it came sooner than the tape i really wanted but i can t recommend this tape i will be switching back to walker tape they also make a single sided tape which must be better than this
