Furthermore, thyroid conditions occur when your thyroid gland is not producing enough hormones Or producing too much of hormones. The most common type of thyroid conditions are as following:
Both conditions (Hypothyroidism & Hyperthyroidism) can cause dry, brittle hair or thinning hair on your scalp and body.
The Link Between Thyroid Conditions and Hair Loss
Thyroid conditions can cause hair loss if they are severe and left untreated. But, before understanding how these conditions cause hair loss, let us first understand the hair growth process.
- Hair starts growing from the roots (bottom of your hair follicles) on your scalp.
- Your scalp’s blood vessels provide nutrients to the root and help in hair growth.
- Hair pushes up and out through your skin. The hair passes through the oil glands that help maintain the required moisture in the hair.
- Hair grows for sometime and then falls off as a new hair growth cycle starts.
Kindly note, the thyroid hormones (T3 and T4) directly affect hair growth and its development. When the hormone production is disturbed, it can lead to hair thinning across your scalp and other areas such as your eyebrows.
Hair loss due to Autoimmune thyroid disease
Most people with Hypothyroidism or Hyperthyroidism have autoimmune thyroid disease. If someone has one type of autoimmune disease, he/she is more likely to develop another autoimmune condition for example:
Alopecia areata: Alopecia areata is an autoimmune condition that causes hair loss in people having autoimmune thyroid disease.
It causes circular patches of hair loss in more discrete areas. In most cases this is temporary and does not progress, but unfortunately it can cause significant baldness.
There are other rare autoimmune conditions that can also cause hair loss :
Hair loss and Antithyroid Drugs
Some antithyroid drugs such as (carbimazole and propylthiouracil) can, in rare cases, cause hair loss. But, it may be very difficult to tell whether the drug or your thyroid condition is causing hair loss.
Furthermore, it is very rare for anti-thyroid drugs or treatment to cause hair loss. Kindly note, Antithyroid drugs are used to treat an overactive thyroid (Hyperthyroidism).
Symptoms of Thyroid Related Hair Loss
Slow and gradual thinning of hair is the most common symptom of thyroid related hair loss. You may notice more than usual hair lose while combing.
Furthermore, hair loss may develop slowly with hypothyroidism and hyperthyroidism. You won’t necessarily see patches or bald spots on your scalp, but, your hair may seem thinner all over.
In most cases, hair loss caused by thyroid conditions is temporary, but regrowth of hairs may take several months.
It is important to note here that, you can still experience hair loss even after starting medicines for your thyroid condition. This is because the hair growth cycle is a months long process. But some people start wrongly blaming the thyroid medicines for hair loss. Unfortunately, if they stop their thyroid medicines, the hair loss problem will become worse.
Kindly note, it is perfectly normal to lose 50–100 hairs from your head each day. However, hair loss beyond this needs medical attention and may be related to thyroid problem.
