How to avoid a reaction to hair dye
Patch test
Always carry out a patch test before using a permanent or semi-permanenthair dye, even if you are using your regular brand.
This usually involves dabbing a small amount of the dye solution behind your ear or on your inner elbow and leaving it to dry. Follow the instructions that come with the dye.
If you develop any irritation or feel unwell after the patch test, don't use the product. You should be able to return the product to the shop for a full refund.
Allergy clinic
You could also have a patch test done at an allergy clinic, to see which chemicals (if any) you're sensitive to. You can then check product labels and avoid products containing these chemicals. However, the clinic may not test all hair dye chemicals.
Other precautions
If you don't develop any reaction from the patch test, you can continue to use the dye, but make sure you:
- don't leave it on for longer than the recommended time
- wear gloves when applying the dye
- rinse your hair thoroughly afterwards
- carefully follow the instructions included
