I tried Badlab, it's easy to use and wash off, but I think I'm sensitive to the fragrance they use, got a headache whenever I used it. Had to stop using it.

There's a newish brand Machine that is also sold in Guardian/Watsons, not bad too, similar price to Badlab. The clay hold isn't very strong, but easy to wash off.

Whenever I want a bit stronger hold, I still have to use some Gatsby hairspray. Clay that is easy to wash off won't have strong hold.
