Hashimoto thyroiditis is a condition that refers to long-term inflammation of thyroid glands. This is an autoimmune disease that promotes antibodies in your body that inflame and attacks thyroid glands.

What is the thyroid?
The thyroid is a vital gland that plays an active role in the growth and development of the body. It produced hormones that create a coordinating function among body functions. the Thyroid hormone is directly involved in human hair growth and structure building

Relation between Hashimoto Thyoiriditis and Hair Loss:
Hashimoto Thyroiditis causes hypothyroidism that is one of the common reasons for Hair Loss in humans. Hair has a specific growth and development cycle. Prolonged thyroid disorder disturbs the hair re-growth cycle.

Disruption in thyroid hormones, T3 and T4 affect numerous body functions including hair development. Your hair does not grow at a normal speed. In this condition, hair reaches its normal age and falls, but new hair does not replace it.

Symptoms of thyroid-related hair loss:
It is possible to have Hashimoto thyroiditis without knowing it. The symptoms are not noticeable when it starts. Hashimoto thyroiditis may progress over the years causing chronic thyroid damage. Thyroid hormone in the blood drops gradually.

Hair falls in Hashimoto Thyroiditis:
Hair fall in this condition is quite different from the normal male- pattern- baldness. Hair does not fall in any specific pattern instead a diffuse thinning on the entire scalp is visible. Signs may resemble those of hypothyroidism.

Genetic reasons:
People suffering from such hair loss may have someone in the family suffering from thyroid or autoimmune disorders.

Hormonal Imbalance:
The hormonal disorder is a major cause. The thyroid stops producing enough hormones that affect hair growth and development. Hormones T3 and T4 are likely to disturb during this disease.

Other autoimmune diseases:
Having an autoimmune disease can trigger other autoimmune diseases such as Alopecia Areata and celiac disease. Both of these can lead to severe or patchy hair loss.

hair loss can be caused by some thyroid managing medicine. Once you stop taking then the hair will start growing again.

• Other autoimmune diseases: People suffering from other autoimmune disorders, arthritis, lupus, VitaminB12 deficiency, type 1 Diabetes
• Digestive disorders: inflammatory issues, the poor digestive system caused by an autoimmune disorder
• Radiation exposure: people more exposed to environmental radiation are more prone to catch the disease.

Some other blood tests can also be suggested such as antibodies, other thyroid hormones, free T4 test, and cholesterol. These tests determine the hormonal, thyroid, or immune disorders that cause hair loss.

• Hair examination:
A complete hair follicle examination is possible to determine the stage of loss. Pull test, and pluck test determines the phase of the growth cycle.

Conventional treatment of hair loss due to Hashimoto thyroiditis is Levothyroxine. It is a synthetic hormone used to replace T4 (thyroxine ). Regular use can bring back the right level of your thyroid hormone. By use, the symptoms will disappear.
You would follow a regular check-up to monitor your hormone level and quantity of dose. You may need to take medicine throughout your life

Is hair loss due to Hashimoto Thyroiditis reversible?
There are two conditions:
1. If the disorder is diagnosed in the early stages, the hair loss is revisable. You would prescribe medicine to regulate hormones. Once they are in order you can have hair back.
2. If the disorder has developed other autoimmune diseases in the body it may become difficult or even impossible to get back hair. ( Such as alopecia areata)

But the good news is mostly hair grows back as the hormones are normalized. After a child’s birth, women often face the situation, but gradually the hormones balanced up and the hair cycle work normally.

Dietary precautions for Hashimoto thyroiditis patients:
There is a strong relation between Hashimoto thyroiditis and alopecia. A special dietary chart is recommended to the patients to eliminate nutritional deficiencies and food allergies. A suggested diet should be;
• Gluten-free
• Pro-biotic enriched
• Iron-rich

Some foods are suggested to add in diet that helps to absorb thyroid medication, levothyroxine e.g.
