While colouring hair is fun, there are a lot of side effects that one needs to be aware of. The symptoms and damage caused by hair colour may not always show up immediately. It may take up to several days or even weeks after hair colouring sessions. If colouring your hair is quite a frequent affair for you, the chances of something severe happening go up. Here are the disadvantages of colouring the hair.
Whether one is colouring their hair to hide the greys or just experimenting, they could be risking severe allergic reactions. The primary perpetrator of allergies is a substance called paraphenylenediamine or PPD. The most common symptoms include itchy scalp, redness, and swelling in the scalp, mild dandruff, swelling around the eyes and eyelids, and scaly skin around eyes, nose and face.
If one colours their hair often, it gets over-processed because of chemicals present in the dyes. The chemicals strip moisture from the tresses, separate cuticle scales, and make them dry and brittle. The hair ends up losing its shine. Thus, one will have to ultimately compromise on their length because the solution for getting rid of the damaged locks is, unfortunately, a haircut.
Hair colours may also cause some skin reactions. Common symptoms for this include burning sensations, redness, flaky skin, itchiness, and discomfort. It is advisable to perform a patch test 48 hours before getting your hair coloured. During a patch test, suspected allergen is applied, and the skin is examined after two days to make sure there was no allergic reaction. Abstain from using the hair colour at the slightest hint of any allergic reaction on skin.
Often, individuals report of getting red rashes on their scalp after applying hair colour. This indicates that the person is allergic to hair colour. The rashes appear in the place it was applied to, and any area that is exposed to the colour. Hair colours can cause some serious rash that might cost all the hair one has.
Numerous studies have shown that hairstylists, who have a much higher exposure to hair colours, are more vulnerable to getting skin allergies and contract asthma. This occupational asthma is a consequence of constant exposure to PPD in hair dyes and persulfates used in bleaches. This exposure sensitises their airway passage and makes it difficult for them to breathe.
