Can Allergies Cause Hair Loss

Can allergies cause hair loss? That is an intriguing question that not many are prepared to answer. One thing is to know what an allergy is, and another is to understand how allergies are related to hair loss.  

Recent studies show that there are allergies related to cases of alopecia. What worries us most is alopecia areata. When examining several patients with this condition, they discovered many suffered from other allergies as well, according to the National Alopecia Areata Foundation

If we understand it, we can be sure whether can allergies cause hair loss or not. Therefore, it is best to be sure if a connection between alopecia areata and allergies exists.

There are other allergies such as asthma, dermatitis, and atopic rhinitis. Who could imagine that these allergic reactions could be related to alopecia areata?

Because they all share a genetic resemblance to the way, our immune system reacts. That is why it is natural to try to deepen your understanding of alopecia areata, as one of the five reasons considered here that answer the question, can allergies cause hair loss?   

Alopecia Areata

Alopecia areata is an autoimmune disease. Being such a disease, instead of protecting the body from infection, it attacks certain areas, like scalp hair follicles.

The symptoms of alopecia areata are hair loss in some scalp regions, such as round patches of baldness or thinning of the hair. It can also cause tingling or even pain in the area of hair loss.

You could also have one or more accompanying autoimmune diseases, such as thyroid problems, type 1 diabetes, or systemic lupus erythematosus. The funny thing is these diseases also cause hair loss.

There are allergies related to alopecia areata, such as asthma, allergic rhinitis, hay fever, atopic dermatitis, and other forms of eczema.

These related diseases are known as comorbid diseases, which means that one condition or disease exists in the body simultaneously as another.

Can Allergies cause Hair Loss due to Food?

One of the reasons that allergies occur is because although the intestines must digest the food we eat when we have an excess of a Candida Albicans fungus in our body, they take root in the intestine, and the wall of this is perforated.

So when an undigested food particle escapes through the intestinal wall, the immune system interprets it as a foreign substance because it is not customary to see food that way in the blood.

When that happens, the immune system produces antibodies and creates an allergy to that food, thinking that it is harmful, even if it is not. But the question remains, can allergies cause hair loss due to foods?

According to The Belgravia Center, the relationship between food allergies and hair loss is remote. If someone loses their hair due to such an allergy, then it could be that there are several reasons behind it.

First, the person who thinks they have a food allergy may not have enough vitamins, minerals, or nutritional supplements that the body needs.

That could affect hair development. In addition, many of those who suffer from allergies also have hormonal imbalances, such as thyroid diseases and adrenal disorders, which are often related to hair loss and thinning.

Stress can be another trigger because it often creates temporary hair loss. However, the vast majority of allergies do not. Most of these, by themselves, are not diseases that cause hair loss. But some do. Which? Let's start with the first one.

Hair Dyes and Hair Loss

Hair dyes are one of the issues that must be taken into account to know if allergies can cause hair loss or not. Some dyes their hair, for a more attractive appearance, of course.

But the least they imagine is that there's a chemical in those dyes that cause hair loss.

This substance is called Para-Phenylenediamine, or PPD, and is present in two-thirds of all existing dyes. PPD causes an allergic reaction on the scalp called contact dermatitis.

In the area exposed to PPD, dermatitis causes swelling, itching, and small red patches. So, the use of some dyes creates an allergy that causes the hair to fall out.

In this case, that would be allergic contact dermatitis, which triggers Telogen Effluvium. There, yes, the hair begins to fall out. If you want to know more about this condition, you can go to this link.

Allergy to Mold and Hair Loss

Mold is another problem that causes an allergic reaction in the body. If you expose yourself once, maybe nothing will happen. But what if one has mold in the house?

In that situation, one would be overexposed to mold. That would cause an allergy that triggers histamine production in the body. This overexposure creates a general inflammation of the skin, including the hair follicles of the scalp.

That same inflammation prevents blood flow to the scalp from being maintained, and by lacking the nutrients that go into the bloodstream, the follicles weaken, and if the person continues to expose to mold, hair loss occurs.

The more a person expose to mold, the more hair will lose and become permanently bald.

Drug Allergy Hair Loss

What I'm looking at here is, can allergies cause hair loss? Although I could also talk about the side effects of medications.

Now, how is the condition that causes hair loss known when using drugs? Can allergies cause it? What are the symptoms, and what medications cause it to occur?

An allergy to oral medications is not so dangerous as to cause hair loss unless the reaction that causes it is inflammation of the scalp since this would prevent enough nutrients from reaching the hair, and it would go weak.

However, topical medications are different. Some cause an allergic reaction, called allergic contact dermatitis. This condition occurs due to any cream, gel, or lotion substance with some foreign element. What are its symptoms?

·        Hives or local burning and itching can occur from a few minutes as soon as the medicine is applied to an hour later. 

·        Red dots

·        Swelling

In most cases, the rash clears up in 24 hours or less from when you stop the medication.

What leads to allergic contact dermatitis causing hair loss is Telogen Effluvium. If you want to know more about this stage of hair growth and loss, click here.
