Why a patch test is essential before hair colouring


If you enjoy experimenting with your hair colour every now and then, you must be well aware of the importance of patch tests or allergy tests. Even if you are not allergic to any hair dye, there are chances of you developing an allergy at a later stage. Make sure that you get a patch test done before taking the plunge. Better safe than sorry.

It is also better for the hairstylist to know beforehand if you are prone to get an allergic reaction after the hair colour has been applied. In fact, a patch or allergy test is an essential safety and health requirement.

Keep on reading to better understand what a patch test actually is.


All you need to know about patch tests

It is an allergy test that is conducted at the salon before hair dyeing. Doing a patch test ensures that the client doesn’t have allergies to the hair products being used. Typically, for the patch test, a small quantity of hair dye is applied on the skin, like the wrist, which is hair-free. Besides, the hair dye patch test can be performed behind the client’s ear. After the product has been applied, you have to wait for some time to see whether the hair colour has caused any allergic reaction or not. Remember, hair colours are not the only products that require a patch test. You might need to get a test done if you’ll use products such as perming lotion, eyelash, and eyebrow tints, etc.


Time duration of a patch test

Some people can get allergic reactions almost instantly, while others might have to wait for at least 24 to 48 hours to see whether there are signs of swelling, redness, or itchiness. Make sure to do the patch test, especially if you’re using a hair dye for the very first time. Moreover, it is recommended to do the allergy test every few months. You never know if the manufacturer has tweaked the formula and added new ingredients.


What if you don’t want a patch test?

Whether you’re colouring your hair at home, using a box dye, or you book an appointment with your hairstylist for this purpose, a patch or allergy test ensures that the product you are using is safe. If you don’t want to get a patch test done, you might be susceptible to severe allergic reactions. Some might only end up with a rash or an itch, but there have been cases where the eyelids swell up so much that they are unable to open their eyes. In extreme circumstances, one could even have breathing problems, leading to death, or experience permanent scarring on the face.

Make sure to do a patch test whenever you are going for a hair colouring treatment. Being a little careful won’t hurt. If you’re searching for professional hairstylists to do your hair dye job for you, look no further. Visit our website and let us take care of your beautiful tresses.
