Tatty -- I know I have seen you recommend a foil cap for those attempting highlights at home. What is the name of it and where do you buy it??
My other question . . . I have only used a cap once, many years ago, and results were far from optimal. How on earth is it possible to control which bits of hair you are highlighting when all your hair is jammed under a cap and you can't actually see it?
Not sure if I am really going to do this, btw! Might well chicken out.
