I am so happy with this purchase! I got the 22inch platinum blonde so that I could have my hairstylist match them to my hair color. I brought them to her so she could do a test strand on them to see if they were A) good quality and B) worth dying. She said they felt great and that they took the color perfect. I read a review that says not to use over 300degrees of heat on these and that’s what I’ve been doing.c because they are processed. I accidentally got the 7pack instead of the 9 pack, but I love them so much that I am going to order the 5 pack so that she can dye those for me too at my next appointment. I have very thick hair so I think they would look even better if I could add some more slight density with a few more wefts but as you can see they blend and look gorgeous even with the 7 pack. I bought the Wet Brush Pro and it GLIDES and detangled these extensions like a dream. I also use the K18 hair oil and heat protection (IGK spray) and it’s incredible! They hold a curl fairly well and even after washing them twice, toning them, dying them and using heat on them they are still going strong. I see these lasting me anywhere from 6 months- a year depending on how often I decide to wear them. My only complaint is that the clips aren’t the best so sometimes I have to Bobby pin them down. I might opt for the seamless extensions for my next order and see if that fairs for me better. overall, I would compare these to the OG Sally’s beauty extensions I used to wear when I was 18 and those suckers lasted me forever. Don’t walk, RUN to try these out! They definitely aren’t the thickest extensions but they are a great density and they don’t hardly shed or split at all.
