Straight talk before you book
- I turn people away. Colour history, breakage and past treatments decide it, not your wallet.
- Next time, only the new growth gets done. Overlapping is how hair gets wrecked, and I don't do it.
- It'll pong a bit and the iron might smoke. Nobody's died.
Don't cook your hair.
