First I’m going to say that the hair was USED before I received it and it was very obvious. But I had an important event to go to so I detoxed and cleaned the hair really well and let air dry. Cute hair and very curly and full. Wouldn’t buy again because why send something used? Especially a wiggggggg ?!?!!!

100/10 so good. obviously it is synthetic so if you’re not taking it off at night it won’t last as long. i’ve worn to sleep and it’s been a about a week and it’s starting to get a little tangled but not too bad. it is A LOT of hair so it’s big, so if that’s not your style i wouldn’t go for it. ive gotten SO many compliments on this hair, will be reordering
