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 3 days after install. And 3 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.
