Experimenting with hair colour can be a fun way to update your appearance, show off your individuality, or just hide those annoying greys. The wide variety of hair colour options available today, ranging from bold reds to delicate browns, allows for infinite experimentation. But in the midst of the thrill of changing your hair, it’s important to put safety first. The hair colour patch test is a straightforward but frequently disregarded process that can be the difference between a gorgeous new appearance and an excruciating allergic response.
Although generally safe, hair colour is made up of a complicated blend of chemicals. These substances, which include ammonia, resorcinol, and paraphenylenediamine (PPD), are necessary to produce the intended colour shift but may cause allergic reactions in certain people. From minor redness and itching to severe blistering, swelling, and even the potentially fatal allergic reaction known as anaphylaxis, these reactions can vary widely.
Before applying a hair colour product to your entire scalp, a hair colour patch test is used to determine whether you have any possible allergies to the particular product. By taking this preventative step, you may determine how sensitive you are to the chemicals in the hair colour and steer clear of an uncomfortable and possibly harmful situation.
Why is patch testing for hair color so crucial?
Although there is little chance of a severe allergic reaction to hair color, the repercussions can be serious. An itchy, irritated scalp could be the result of a minor reaction, but more serious side effects could include:
The most frequent allergic reaction to hair colour is contact dermatitis, which is characterised by blistering, itching, swelling, and redness of the scalp and surrounding skin.
Burns to the scalp: Some hair colour chemicals can burn the scalp, causing discomfort, redness, and sometimes hair loss.
Eye irritation: When hair colour gets in the eyes, it can irritate them, make them red, and even temporarily impair their vision.
Respiratory concerns: For sensitive people, breathing in the fumes from hair colour might cause asthma attacks or other respiratory problems.
A rare but potentially fatal allergic reaction, anaphylaxis can result in breathing difficulties, throat swelling, and a drop in blood pressure.
You can greatly lower your chance of having these negative responses by doing a hair colour patch test. It enables you to detect a possible allergy before it develops into a more severe medical condition. The possible discomfort and medical costs of treating an allergic reaction greatly exceed the little time and effort needed for a patch test.

Repeat (if required): Do a different patch test for each hair colour product if you are using more than one, such as highlights and a base colour.
Past the Patch Test:
Every time you colour your hair, even if you have previously used a certain hair colour product without experiencing any problems, you must conduct a patch test. Even a small alteration to the hair colour mix might cause a reaction, and your sensitivity to chemicals can change over time.
