Side Effects Of Hair Dyeing

If you are having fun after dyeing your hair, I guess you should sit back for a while and read this article. You have a life threat coming!

I’m kidding! Relax!

You are not dying right now because of your hair dyeing! That means you have all the time to finish this article!

I had no intention of ruining your fun but as now I have your attention and curses obviously, I do believe that together we should discuss a few important facts about the side effects of hair dyeing.

We love colors and we love to see ourselves in colors. A large number of us, the humans, often dye our hair to please or entertain ourselves. If it is not done in proper manners, it can be harmful to hair and also to the body. While coloring hair is amusing, there is something also damaging. The harms it doing don't show up instantly as it takes time to unveil.

Hair Dye Types

1. Permanent/Semi-Permanent Hair Dyes:  

This kind of die impacts on the natural colorant of the hair to make the dye last longer. Permanent hair dyes comprise the strongest kind of oxides that impel the dye inside the hair to last longer.  These kinds of hair dyes last for about 2/3 months. Though Brown is the most used hair dye, a great number of people also search for the longest lasting black hair dye. 

2. Temporary Hair Dyes:

Temporary hair colors are the first choice for people who want to try a lot of different colors. On the other hand, people try it before going for the permanent just for a trial purpose. This kind of dyes contains less or no oxides. It only changes the exterior look and fades away after the next hair wash.

3. Others:

There are also a few hair dyes, instead of coloring they lighten the natural color. These processes are called bleaching. Another kind of hair dye which is Ammonia-free causes less side effects than other hair dyes                  

Side Effects Of Hair Dyeing


Amongst all the side effects of hair dyeing, this one comes in the first place. Due to too much coloration, the natural hair can face discoloration! And after that, you'll need coloration again and it will discolor your hair again and the cycle continues... Eventually, insignificantly over processed hair can be revived with hair treatment, if not you'll have to cut them off. 

Most of the permanent dyes contain acidic and oxide materials which cut deep into hair body and damage the natural pigment of the hair. As a result after a certain volume of dyeing the hair won't progress back to its natural tone. 

Reduction of Hair Health

Constant use of hair dye for a long time, particularly the permanent types make the hair fragile and unhealthy. It damages the scalp skin which makes the bottom of the hairs weaker.  Regular treating hair with chemicals can damage the hair at an extreme rate.

As a result, the hair will break easily, wash away with water while in a shower. It definitely won't be a great sight for you to see your beautiful hair lying on all over your bathroom floor!

Allergic Reaction

It is quite often hair dyes cause allergic reactions because most of the permanent hair dyes comprise paraphenylenediamine (PPD) which is a well-known frequent allergen. In general, the allergic reactions are itching, skin tenderness, redness or swelling on the scalp or sensitive areas nearby.   

There are also cases of triggering an anaphylactic shock which one is a life-endangering allergic reaction. No previous history of allergy has no relation to the allergic reactions of hair dying. The more one uses hair dye, the more the possibility of an allergic reaction increases.


The researchers found out in 1980 that a few of the amines are capable of causing cancer. It was confirmed by experimenting the hair dyes on animals. However, the hair dye manufacturer companies stopped using those amines to make the hair dyes safer.

There has been a link found between a few types of cancers (bladder cancer, Non-Hodgkin lymphoma, Leukemia etc.) and hair dyeing after implementing and observing on animals and isolated human cells. Though there aren't any strong evidence of a definite outcome of the research yet.


Hair dyes contain Persulfates, a chemical which is very common about harming our nose, throat, and lung. As a consequence of regular use of that chemical coughing, wheezing and/or shortness of breath takes place.

Pregnancy Complications

Most of the hair dyes contain a common chemical called Lead Acetate. If you are a male and were relaxing, you too have a concern here.  Researchers hold on a fact that this chemical has a connection with the fertility of both male and female.

Though FDA research has stated that the volume of lead carried in hair dyes are not sufficient to generate a lead poisoning.   It is strongly suggested not to use hair dyes while on pregnancy because the substances present may cause malignancy in the expected child.


Like every other thing around the hairs after dyeing requires a lot of extra care. It includes everyday home care, visiting a salon once or twice in a month. It will be needed to buy beauty products that are particularly formulated for dyed hair. Right after the dyeing session, hairs are most likely to be vulnerable to the threats. In this period hairs also need extra care to avoid damages and to keep the health, shining and lusters.


Sometimes chemicals on hair can make contact with the soft parts of the face or the eyes. It can cause conjunctivitis or pink eye or inflammation.

Precautions To Avoid The Side Effects

If you are scared after all these threats, I guess there should be something in the discussion that comforts you. Despite all the side effects of hair dyeing, there are also a few precautions which can help reduce the chances of side effects.

1. Avoiding permanent hair colors can reduce big chances of risk. While avoiding permanent temporary colors can assist the dyeing. As we have already discussed it earlier that the temporary colors don't contain unhealthy chemicals.

2. Taking help or guidance from a professional is a great thing to do. Self-doing can go wrong most of the times. A professional touch can serve the hairs best and avoid a possible disaster.

3. Maintaining ventilation while dyeing is important. A shallow place with less ventilation can cause nasal and eye contamination. 

4. A patch test before starting the hair dye is important. It can identify the allergic possibility of the hair and help whether the hair is fine enough to be processed.

5. Always buying products from good, renowned and loyal brands who have a history of using very less chemical. Spend extra money if needed.

Final Words

It is apparent that the side effects of hair dyeing are quite scary and alarming. Following those few particular precautions can reduce the chances of damage. But the best solution is to use natural alternatives like Henna, Lemon, coffee etc. to have luster and shining on hair.
