What diseases can make hair fall out?

Most people normally shed 100 to 150 hairs per day. This usually doesn’t cause noticeable thinning of scalp hair because new hair is growing in at the same time. However, if excessive hair shedding continues for longer than three months, seek the advice of a dermatologist. Chronic hair loss can signify that something isn’t quite right internally. The most common causes of long-term hair loss are usually; vitamin deficiencies, or underlying diseases that can make hair fall out like crazy.

Hair loss occurs when the cycle of hair growth is disrupted or when the hair follicle is destroyed and replaced with scar tissue. Reasons can range from the simple and temporary—a vitamin deficiency—to the more complex, like underlying diseases. Luckily, in most cases, excessive hair shedding can be reversed once the condition is treated. 

Possible diseases that lead to excessive hair shedding

Some medical conditions and diseases are often to blame for excessive hair shedding. These conditions can make hair fall out in huge amounts and in some cases hair doesn’t grow back. However, most hair loss in these cases is treatable once the diseases are cured. Here are the common diseases you might be suffering from if you have excessive hair shedding:

Ringworm (tinea capitis) is a very common infection among children throughout the world. It is not caused by a worm but by a fungus infection. This infection causes round patches of baldness or scaly skin on the scalp. It is most common in children of 3 to 9 years old. You can catch ringworm by sharing hats, combs, brushes, towels, telephones, or sports equipment. Treatment occurs over a course of weeks to months. So generally, scalp ringworm infections are not emergencies, but require a doctor’s examination  to start appropriate treatment.


excessive hair shedding/what-diseases-can-make-hair-fallIf you’re feeling under pressure, tired and on top of that have excessive hair loss then you most likely have anemia. It means that your hair loss could be the result of a low amount of red blood cells in your system. The body depends on certain nutrients to produce more red blood cells. However, if your system lucks one or more of these nutrients, anemia will develop. The most common form of anemia is iron deficiency. It usually occurs if your diet lacks iron-rich foods, or you aren’t absorbing it correctly. However, loss of blood, illness and pregnancy can also be causes of anemia. If you’re losing your hair, or notice it isn’t growing at the rate or to the length it used to, you have to see a doctor to test your iron levels. Because both of these can be symptoms of anemia. 

Autoimmune diseases

Autoimmune diseases are conditions in which the immune system mistakenly attacks the body. In this type of diseases, the immune system destroys healthy tissue thinking they are a foreign substance or infection. The most common kinds of autoimmune diseases that can make hair fall out are:

  • Lupus: This is a chronic autoimmune disease in which the body’s immune system becomes hyperactive and attacks normal, healthy tissue. Hair loss occurs because the immune system mistakenly destroys hair follicles. Although a few people with lupus will lose clumps of hair, the disease can also cause gradual thinning of the hair on the scalp.
  • Alopecia Areata: When you have an autoimmune disease, your immune system attacks your own body. With alopecia areata, it’s the hair follicles that are attacked. This autoimmune system can cause different types of hair loss. Alopecia areata (hair loss in patches). A. totalis (lose all hair on the scalp). A. universalis (lose all hair on the body). This diseases is treatable and hair usually grow back after the patient finishes the treatment.                                                                                                
  • Systemic Sclerosis (Scleroderma): This autoimmune disease is typically common in people of 30 to 50 years old. However, it can develop at any age. Women are more likely than men to suffer from this condition. And the symptoms and severity of the condition vary from one person to another. In the early stages of this disease, you may notice your skin thickening and shiny areas developing around your mouth, nose, fingers, and other bony areas. As the condition progresses, you may notice several symptoms including excessive hair shedding.

Hair loss is another sign that thyroid hormones may be out of balance. Both overactive and underactive gland can make hair fall out. The hair follicles follow a natural cycle of hair growth and resting phases. Most of our hair is growing while only a small portion of it is resting. Because hair growth cycle depends on the proper functioning of the thyroid gland, abnormal levels of thyroid hormone produced by this gland can result in hair changes. When these changes in the body throw off that cycle, too much hair rests at one time and not enough grows. As a result, you’ll notice excessive hair shedding, thinning hair, or balding. Luckily, in most cases, the hair will grow back once you cure the thyroid disorder.


what-diseases-can-make-hair-fallCancer is not exactly the reason of hair loss. But the chemotherapy that some types of cancer require can make hair fall out. What happens is that chemotherapy drugs don’t only destroy caner cells but also healthy hair cells all over the body. Fortunately, hair will grow back once the patients finish their treatment. However, this may take long time but will eventually grow back to normal within 6 to 12 months.  

Bottom Line

Hair loss can be a potential side effect or symptom of many diseases ans illnesses. It is very important to keep an eye on how much hair you lose per day. If the lose exceeds the normal amount we mentioned in this article, then you most likely are suffering from an underlying health condition. The best way to deal with it is to visit a specialist to keep your condition under control.
