Are hair dye patch tests safe?
So, although it is inconvenient, a patch test is designed to protect you from harm and is therefore an essential part of the process of colouring your hair. Any hairdresser willing to dye your hair without a patch test is not fulfilling their legal requirements and is certainly not a safe pair of hands for your hair.
How long does a hair dye patch test take?
It takes two days to get the results of your hair dye patch test. Why 48 hours? In order to detect a potential allergy to the hair dye, you need to give your immune system time to respond. Most allergic reactions will occur within 48 hours of skin exposure, hence the 48-hour window for the *hair dye patch test*.
Can I still dye my hair if I’m allergic?
If you have an allergic reaction to hair dye, even mildly, stop using the product completely. You may have a more severe reaction with added use as your system becomes sensitized to the chemical. If you use black temporary tattoos, you may be exposed to additional amounts of PPD.

Can I do an allergy test at home?
One way to do that is through an at-home test. It’s important to understand that an at-home allergy test isn’t a substitute for seeing a qualified healthcare professional. However, if you can’t see a doctor in person, a home allergy test may be a good short-term option.
How do I find out what I’m allergic to at home?

How do I get a full allergy test?
