Q: I am allergic to cobalt and nickel. Can I colour my hair? Janet, 13/5/2010
A: nickel is a frequent source of allergy and the reactions can be very nasty. The good news from a product point of view is that these are banned from being added to cosmetics and toiletries. Unfortunately, small amounts of nickel and cobalt may occur naturally in some colours used in products such as eye shadows. The presence of these small quantities will still be safe and normally this would not cause any problems, but depending on the severity of your allergy you may wish to contact the manufacturers of your preferred brands to check on the suitability of the products for you. Their address can be found on the pack which you can always take note of before you buy.
As for coloring your hair. This might be a difficult one – as you obviously have the potential to be allergic to things, and we do know there are certain hair dyes that can cause allergic reactions – although these are fairly rare. This is why manufacturers label on pack and in the instructions to perform a skin sensitivity test 48 hours before each colouring, on a small area of the body. If someone is allergic to any of the ingredients in the hair colorant then they would experience a reaction in that small area which would tell them they can’t go on to colour their hair and risk a larger reaction on the head.
As you are already known to be allergic to cobalt and nickel then it is very likely that you could be allergic to other substances too. However you may have been tested with hair dyes as part of your hospital testing – so you could always check this with the department where you had your allergy testing.
Going for highlights might be a possible option because if the hairdresser uses a rubber skull-cap or foils then the contact with the scalp is reduced even further. Your hair salon may also be able to advise you further on this. Again though if the manufacturers advise performing a skin sensitivity test before coloring then it’s really important this is done.
