good quality hair [SEP] i ended up dying mine black because i naturally have very dark hair and i was tired of maintaining the lighter color with bleaching and all that jazz these actually were very easy to dye and look great i did not glue mine in i ended up using some clip in extension pieces and making a ponytail extension out of it it looks great and the hair is really excellent qualityif you are using them as glue in extensions you will definitely need at least sets of these to get a decent amount of hair throughout your head it is just not enough otherwise
