Review (1/5): wouldn't buy again
the English instruction on website is unclear, I just used the product and I am very disappointed. i don't feel like it works to straight my hair, instead, I feel like I was taking an hour and half just to wash my hair. the substance felt like glue and made my hair stick together. I don't feel smooth on my hair. I think a better shampoo and conditioner works better than this.. would not recommend buying it. totally a failure. besides, the product they sent is different than described, I thought it's just an upgraded version so I did not pay attention to it. just don't buy it, waste of money
