Query: Not good

I'm not sure where all these glowing reviews are coming from, but I am not at all impressed with this reconstructor. I've used it several times and each time it leaves my hair feeling limp and tangled afterwards. I much prefer the reconstructor that comes in the Optimum Care relaxer boxes which leaves my hair feeling thicker and smooth. This stuff is going in the garbage.
