Is Gluten Causing Your Hair Loss?

Gluten Intolerance and Hair Loss

Hair loss can be confusing and disorienting no matter what. But if your hair loss isn’t following the typical pattern for male pattern baldness — or if you’re a woman — it can be particularly baffling.

Maybe it’s all the gluten you’re eating.

Gluten is a protein found in wheat products as well as rye and barley. It’s also used as an additive across a wide range of packaged and prepared food products, as it serves as a filler and helps foods adhere and retain their shape.

Some people have an intolerance to gluten. This intolerance may be mild or very severe. Celiac disease, one of the most serious forms of gluten intolerance, causes an immune system response that can damage the small intestine.

It’s by no means common. But for some people, an undiscovered gluten intolerance can lie at the root of their hair loss. The connection is especially strong for those with full-blown Celiac disease, which can often go undiagnosed or misdiagnosed.

Here are a few ways gluten intolerance, particularly Celiac disease, can cause hair loss.


Through Vitamin Deficiency

Celiac disease can be challenging to diagnose, because many of the symptoms—diarrhea, weight loss, fatigue, abdominal pain, numbness or tingling in the hands and feet, skin rashes and more—are diffuse and variable, and can be symptoms of many different conditions.

Some people wind up going misdiagnosed or undiagnosed for years, during which the disease has plenty of time to damage the lining of the small intestine and promote overgrowth of harmful bacteria.

Both of these factors limit the small intestine’s ability to absorb certain nutrients, vitamins, and minerals. A deficiency in these nutrients can slow down your hair’s natural growth cycle and ultimately result in hair loss over time.

Through Alopecia Areata

Alopecia Areata is also an autoimmune disease that causes hair loss. It occurs when your immune system is triggered to attack your hair follicles.

This disease is not well understood. But studies have shown that there is a connection to Celiac disease. A 1995 study published in Gastroenterology was the first to document that connection.

Not only did the study find that the Alopecia Areata patients had a higher rate of infection with Celiac disease than could be predicted by chance, but that some patients had no other symptoms of Celiac disease—demonstrating that in some, Alopecia Areata may in fact be the only symptom.

A more recent study, published in the Indian Journal of Dermatology in 2014, discovered a high rate of “silent Celiac disease” among children with Alopecia Areata—meaning hair loss was often the only symptom.

The hair loss typically starts as small, round patches on your scalp that may be difficult to notice. The patches spread, however, and eventually you may lose most or all of your hair—both on your head and elsewhere on your body, such as on your eyelashes or eyebrows.

The severity of the hair loss varies from person to person. And while the hair loss may be temporary, it can also be permanent—or come and go, in a cycle of loss and regrowth that can last years.


Through Thyroid Disease

Hashimoto’s thyroiditis is another type of autoimmune disease, which occurs when your immune system attacks the thyroid.

This can damage the thyroid to the extent that it does not produce enough hormones—a condition called hypothyroidism. Hair loss is a leading symptom of this condition.

Research has also demonstrated a connection between autoimmune thyroid disease and Celiac disease. In a 2003 study published in the Archives of Internal Medicine, half of patients with Celiac disease who participated in the study were also found to have thyroid disease.

A more recent study, published in the Journal of Clinical Endocrinology and Metabolism in 2008, studied the connection between thyroid disease and Celiac disease in the largest sample size of any study thus far—14,021 people. It identified a correlation between the two conditions.

Treatment for Hair Loss Caused By Gluten Intolerance

It’s fairly clear at this point that having one autoimmune disease makes you susceptible to others, and that there’s a connection between Celiac disease and hair loss for a variety of reasons.

In fact, many doctors recommend testing for Celiac disease if you’re experiencing unexplained hair loss—as it’s sometimes the only symptom.

There is currently no cure for Celiac disease, and no known cure for Alopecia Areata. In instances where a patient has both, however, the best treatment is to avoid eating gluten.

That means avoiding any foods that contain wheat, rye, or barley. While this still leaves a wide range of foods—from meat and seafood to vegetables, fruits, and rice—available, keeping your diet entirely gluten-free can be a challenge.

Many foods, especially prepared foods, contain gluten—and eating any at all can damage your small intestine. People with Celiac disease have less leeway to be spontaneous in the foods they eat, and sticking to the diet requires a lifetime of vigilance.There is good news, however: if you have Celiac disease, your small intestine can start to heal within weeks. And eventually, with time and vigilance, you should see your hair start to grow back.

If your hair loss is linked to hypothyroidism, your treatment may include taking synthetic thyroid hormones to replace the hormones your thyroid should make naturally. Once your hormones are back in balance, your hair loss should resolve.
