I bought these for my 20 yr old daughter. She has been wanting extensions for a while, but the cost can be outrageous! However, we did a lot of research and came across these. We purchased 4 boxes of them and actually had one box plus a few left over. My cousin is a hairstylist and doesn’t have a lot of experience with extensions, but these are really simple and she did a great job!! My daughter kept these in from right before Christmas until just recently. Now, it’s just time to push them up and rearrange and add a couple only because of her own hair growth. The extras came in handy because sometimes an extension or two can come out during wear. Some people’s hair gets oily, or you could have really fine hair, and that can cause them to slide off, or because you just brush too hard!! It’s normal!! I really want to stress that you do your research on care before putting in extensions. Not just for these, but general extension care. Because if you take care of them like they say and brush your hair carefully when brushing, they will definitely last!With these extensions, my daughter washed them with her normal salon bought shampoo, she used a good hair oil (look up what would be best for you), and she would braid her hair at night before bed, so the extensions wouldn’t get tangled up or knotted while she was sleeping. Just do your research on extension care and you’ll be good!! If you choose these, then you’re on the right road!! These extensions are wonderful and the color we chose matched my daughter’s hair color perfectly!! These extensions are priced great and they are very good quality!!! Highly recommend these awesome hair extensions!!! We will most definitely purchase these again when we need to get more!! I’m including a picture of my daughter with these extensions in her hair. It looks like her natural hair!! No one knew she even had extensions!!
