I had extensions in before that said the product was 100% human hair. But after using Perfect Locks, I know that the other product was subpar. I ordered 16" straight Indian virgin hair with i-tips (fusion using a tube) and it literally feels and looks exactly like my own hair. When I run my fingers through I can't feel the difference! It doesn't shed, or tangle and they lighter than the other extensions I used so my head isn't sore or itchy. I had two packs put in 25 in each pack) and just ordered a third to have added for fullness. I really love this product and I have already recommended it to several people.
