Straight talk before you book
- It'll pong a bit and the iron might smoke. Nobody's died.
- Some systems shift your colour. You'll hear it from me before, not after.
- What comes out stays out. It won't go poker straight either, and that's the point.
- Hair that's already been through the wars? Then it's a no. Or a not yet.
Don't cook your hair.
