Hair Loss 

There are many diseases that cause hair loss. Some of them from stress, others autoimmune diseases. While others are related to hormonal imbalances and vitamin deficiency. The causes seem countless. For complete information, examine the article Causes of Hair Loss.  

Why analyze diseases that cause hair loss? 

What would we say, to add to a list of problems we already have, to contract a painful, debilitating, or even disabling disease? What would we say if apart from that, this disease was the main cause of our hair loss? The only thing we can say is that, it would be frustrating, discouraging and anguishing.

So far, we have only seen the dark side of this. But bringing it to the positive side, it is good to know what really causes our hair loss.

Maybe you are asking now: "Why is important to analyze the diseases that cause hair loss?" Because that way, we can better understand each of them and counteract the cause.

You will see a series of diseases that, the great majority of them cause the hair to fall but some of them not directly. Here is the list:

Acute Stress Disorder

Stress and hair loss are related. This is the first of the diseases that cause hair loss, in alphabetical order.

The loss of hair that comes from stress can occur, either due to a very stressful physical or emotional event such as a divorce, the death of a loved one, injury, illness, surgery, or even serious financial problems.

That hair loss can be seen between 6 weeks to 3 months since the incident occurred.

There are three types of hair loss due to the stress. The first one is, Telogen Effluvium. It happens when stress forces a large number of hair follicles to enter a resting phase. In a few months, the follicles that stay in that phase suddenly begin to fall, with just using a shampoo or combing your hair.

The second is alopecia areata, which occurs when anxiety levels are high. That would provoke white blood cells attack the hair follicles.

Trichotillomania is the third and not the very least. This is an irresistible desire to pluck out the hair from the scalp, eyebrows, lashes, and other body parts.

But hair loss can be left behind, just by keeping stress under control. If stress is controlled, the hair will re-grow.

Allergies

Can allergies be the cause of hair loss? Unfortunately, allergies are among the diseases that cause hair loss. But only certain types, not the majority of allergies.

For example, some usually dye their hair, of course for a good-looking appearance. The least they imagine is that there is a chemical in those dyes that causes hair loss. This chemical is called Para Phenylenediamine or PPD and are present in two thirds of all dyes out there.

So, the use of some dyes creates an allergy that causes the hair to fall out. But the vast majority of allergies, do not. Therefore, allergies per se are not diseases that cause hair loss.

According to The Belgravia Centre, the link between a food allergy and hair loss is remote. If by coincidence someone looses hair loss having an allergy with food, then there could be a good number of reasons behind that.

First, many of those who suffer from allergies, also have hormonal imbalance such as thyroid diseases and adrenal disorder, which are often related to the loss and thinning of hair.

In addition, individuals with food allergy symptoms might well not have enough vitamins, minerals, or nutritional supplements. If a lack of any of these occur, it could affect hair development.

Stress may be just another contributing factor, which will often cause temporary baldness. Some believe there is a relationship between the symptoms of food allergy and alopecia areata. Both are autoimmune ailments. Diseases that cause hair loss or are prone to do it.

Alopecia Areata

Alopecia areata or alopecia circumscripta is an autoimmune disease. This causes hair loss in certain areas of the scalp.

But why is alopecia areata among the diseases that cause hair loss? Being an autoimmune condition, instead of the body protecting itself from infections, it attacks the hair follicles of the scalp.

Although alopecia areata is often noticed in round patches of hair loss, at other times the loss is in the entire head. When this is the case, it is called alopecia areata totalis. When the loss of hair is in the whole body, it is known as alopecia areata universalis.

Anemia

One of the diseases that cause hair loss is not caused by a foreign intruder, but for a lack of an important mineral in our body.

Iron in the blood is necessary for the production of red blood cells. These in turn, carry oxygen to the different cells of the body. If there is an iron deficiency, it would lead to anemia. The result is that less oxygen is taken to the scalp.

When that happens, the body goes into survival mode. Then, it is a priority of our system to keep the vital organs. That makes the body stops sending oxygen to what is not so vital, such as hair for instance, instead of keeping it intact.

That's like the ships of ancient times and some modern ones too. If the ship was on the high seas and faced a storm, the sailors would throw overboard what they did not think are essential. They only would keep what they consider most valuable, like human beings, for example. 

Well, the same happens with our body. Remember that our body system has a brain for itself. When our body detects that red blood cells are decreasing, then they turn on the alarm.

From that moment, they concentrate on bringing nutrients to our vital organs such as heart, brain, liver, etc. Then everything else is thrown overboard, including hair, considering it a luxury. That's why anemia is one of the diseases that cause hair loss.

The contrary is also true. When a patient with low iron blood levels is treated, the hair loss is also less, and the scalp is better prepared to regrow more hair, as WebMD stated.

Until now, we have seen the 1st part of diseases that cause hair loss, that is from Acute Stress Disorder to Anemia. What will come in the 2nd article? I know that curiosity killed the cat, but nothing of that shall happen if you click the button that says next at the bottom of this page.
