It like a temporary tattoo that contains ppd the main culprit for allergic reactions. They're not too expensive about 80p each (they come in packs of 50 plus) but you can just factor this into your prices.
I think they're a life saver especially for them clients who refuse to come for a patch test just post one out and give them another at the end of their treatment. I get mine from salons direct x
So by doing this you don't need to do the skin test? With the hair colour?
