Took advantage of the Black Friday sale and purchased 18" Kinky Straight clip-ins. What arrived definitely did not match my expectations. Most of the hair is about 14-16" with a few whispy 18" hairs mixed in. To use the hair and not look crazy, I would have to cut those scraggly pieces off. The hair does not take a curl with a curling iron, it's not 100% human hair. The return exchange process is so arduous and complicated that this feels like a scam.
