When I first originally got this I was so excited at the way it made my hair look and feel that I went out after a week and bought a second one. It makes your hair silky and super smooth, and using it after hairdrying or straightening your hair is also great as it leaves your hair looking healthy and rid of split ends. BUT after about two weeks I found that my hair became immune to it and it did not work even half as nice as before :( I now use it maybe three times a month because thats the only way I am able to see results.
