I am a licensed stylist (great lengths certified) and I have tried all different kinds of extensions. These are so easy to apply and quick, did not shed!!!!!!, blends seamlessly as promised. Negatives are that they are harder to hide and wear updos and got tacky after a week. I washed them w dishwashing liquid (probably not recommended at the scalp to alleviate my itchyness and they were perfect again. Followed by a deep conditioning treatment. I love them and will buy again.
