This is not 100% human hair [SEP] I don't recommend this hair its not 100% human its synthetic blend the second day i had my hair installed it was tangled and mangled on the ends  . This hair will not hold a curl. very disappointed as i had this hair  sewed in and after 2 weeks I had to take it out. Moreover, the bundles were very thin and the inches are not the right length advertised they are shorter.
