For those of us who use home hair colourant kits, we are advised to always carry out a stand test 48 hours before colouring our hair, to ensure we do not experience any allergic reaction to the product. However, also included in the instructions, is the fact that we must use the entire product straight away! Therefore, in order to follow the instructions properly, we must purchase 2 full size products to colour our hair!

I suggest, therefore, that each pack includes a mini sample kit to be mixed and used 48 hours in advance of the full kit. Failing that, we should be able to purchase mini kits separately, before committing to the full size home colourant kit.
