I used the Silk and Amla DC and it was very strengthening. At first I thought it did nothing, but it worked really well. I had strong hair for about a month. The only thing I didn't like is that it's so thick (not really a problem) but he Conditioner cost $32. I bought it during a 50% off sale just to try, but that's a lot for only two uses. I have a leave In but I haven't tried it yet.
