1. Over Processing:
Ammonia (or chemicals similar to it) and peroxide are the ingredients of permanent hair colors. While ammonia breaks through your hair shaft, the peroxide neutralizes the natural pigment in your hair, stripping away its color, which you can actually call hair damage. Over treating your hair with these chemicals can cause the hair to lose shine, break easily, and in some extreme cases, wash away with water. Moreover, hair care treatments are only effective to some extent to revive the health of your hair. Whereas chopping off your hair is the only way to get rid of the hair damage.
2. Allergic Reactions:
Allergic reactions are pretty common with hair coloring. Permanent hair dyes contain paraphenylenediamine which is a common allergen. Dyes contain PPD and other chemicals, which make people, who have contact dermatitis, particularly prone to reactions. People with skin conditions like eczema and psoriasis should also avoid using hair colors. Not very often though, but in some cases, permanent dyes can cause itching, skin irritation, redness, or swelling on your scalp or other sensitive areas like your face and neck. Also keep in mind, that if you have successfully used hair color in the past, without having any reactions, doesn’t mean that it won’t happen in future. The more you use hair color, the more you become prone to allergic reactions.
3. Affects Fertility:
Lead acetate is a common ingredient of permanent hair colors. Research says there could be a link between this chemical and fertility issues in men and women. Pregnant women must not use any type of hair color as it can cause malignancy in their unborn infant.
4. Expects Extra Care:
Although this is not a side effect, however it is worth mentioning here because a lot of people don’t realize how much extra care is required for the upkeep of colored hair. It’s a long term commitment that will make your trips to salon pretty frequent, there by adding to the extra costs as well. You will need to buy products that are specially designed for colored hair. Moreover the processed hair is prone to damage and demands a lot of time and care. Failing to provide the required time and care will cause your hair to lose, shine and health there by inviting hair problems like hair fall etc.
The chemicals for coloring the hair must be used with a lot of precautions. Failing to take the necessary precautions can result in the chemicals making contact with sensitive parts of your face like eyes etc, which can cause conjunctivitis or pink eyes, thereby causing inflammation and extreme discomfort.
Hair dyes contain persulfates in them, which aggravates asthma. Continued inhalation of these chemicals results in coughing, wheezing, lung inflammation, throat discomfort, and asthma attacks as well.
Cancer causing compounds were present in the hair dyes when the permanent hair dyes were first introduced. Although the formula was altered to replace these chemicals, it’s still a topic of debate as to whether hair dyes can cause cancer or not. And therefore it demands more scientific research to figure out if there’s any link of its use to cancer.
8. Brittle Hair:
Coloring the hair often, makes them over-processed, because of chemicals present in the hair colors. The chemicals extract moisture from your tresses, separating cuticle scales and making them dry and brittle. Your hair also loses its shine and you need to compromise on the hair length, because haircut is unfortunately the only solution to get rid of damaged locks.
9. Irritable Skin:
Hair coloring may cause irritable skin. Some symptoms include burning sensations, redness and flaky skin, itchiness and discomfort. A patch test is advisable around 48 hours before getting your hair colored. During a patch test, the suspected allergen is applied to a portion of your skin, which is examined after 2 days to ensure there was no allergic reaction. If you notice even a slightest hint of allergic reaction, you should avoid using that hair color and also see a dermatologist if the swelling or itching continues.
Many people who are allergic to hair dyes report getting rashes on the scalp, where the dye was applied and any other area that was exposed to the dye. You must see a dermatologist immediately, so that the allergy can be treated without any delay.
11. Hidden Costs:
Hair coloring and especially maintaining the hair afterwards is a costly affair. So make sure, you are aware of all the expenses before you choose to color your hair, so that later on it does not hit your pocket unexpectedly.
