DO NOT BUY THE TAPENINS , omg I have only washed w the specific hair shop shampoo and conditioner , only wash 1-2 a week . Used the specific extension spray to detangle and freshen up . I spent $700 on 2 packs of the skin weft hair extensions and by week one the split ends were out of control . The tape they come with sucks too . Second day it was gooey and by 3 weeks all of them slid out . Didn't have that problem on second install when I used the tape from Sally's . VERY disappointed . I had purchased utip from them before and it was great .
