This can be explained in part to be because the fragrances used in patch testing does not include all contact allergens only those which most commonly cause a reaction.
. A negative result to a patch test of the dye prior to using it does not guarantee freedom from reaction because the patch test itself could cause sensitisation and result in a rash the next time the hair is. Put some dye directly on your skin generally behind your ear or in the fold of your arm leave it. Therefore a negative patch test does not mean you do not have an allergy.
However a negative patch test could also mean you are suffering from irritant contact dermatitis. Some dyes use a chemical called paraphenylenediamine which can cause some people to have an allergic reaction. If the dye you use contains this ingredient it is best to do a patch test on a small area of skin before applying it to your hair.
