Bar shampoo and conditioners

[BG2015]

I'm going to be travelling for a month soon and don't want to take bottles, so what bar hair stuff is good.

I have very dry, coarse, thick hair so need a decent conditioner. I may have to take a bottle of conditioner if I can't find a good enough one.

I used to like the lush shampoo bars, they last for ages. Never managed to find a solid conditioner that actually works though.
