thin horse hair [SEP] first things first they are easy to install and comfortable to wear they are very thin and stringy looking at the ends so you have to order longer then what you want which means you pay more just so you can cut the hair to not look thin and stringy they last about a week then they look like bad and dry out really bad this is without me washing or doing anything to the hair at all there are also a lot of black hairs mixed in this is def horse hairwhich isn t fair considering the price
