This product is extremely bad. It is the worst thing I have tried so far. I applied it following the instructions and then washed my hair with the same series shampoo. My hair was so dry, so hard that I hated it. I tried the shampoo alone and it's fine, but for some reason, the shampoo with the oil is disastrous. Even the mask didn't soften my hair afterwards. It is truly the worst product I have ever tried in my life so far.
