Thyroid disorders such as hypothyroidism and hyperthyroidism can cause hair loss as a symptom. The thyroid gland produces hormones that regulate metabolism and body temperature, and these hormones also affect hair follicles. Experts are unsure of the exact mechanisms, but thyroid issues may cause stress on the body and disrupt the hair growth cycle, leading to telogen effluvium where hair sheds earlier than normal. Hair loss can occur on the scalp, eyebrows, and other areas, and is also linked to medications used to treat thyroid disorders.

2. Indeed, when hair loss is an issue, it is always crucial to
consult a doctor for proper diagnosis and treatment. One
of the causes of hair loss is thyroid dysfunction. It is
disconcerting enough to be diagnosed with any thyroid
disorder. Hair loss, among one of its symptoms or effects,
makes any thyroid-related disorder more insufferable.
Located in the neck, the thyroid gland produces thyroid
hormones that basically produce available energy for the
body, regulate the body temperature, and help other
organs do their individual functions. The follicle cells are
those responsible for secreting thyroid hormones that
contain iodine, thyroxine, and triiodothyronine. These
hormones produce protein and improve oxygen supply.
Other thyroid hormones including calcitonin and
parathyroid regulate the calcium levels.
The Role of the Thyroid Gland
3. Thyroid problems such as hypothyroidism (insufficient
production of thyroid hormones), hyperthyroidism
(overproduction of thyroid hormones), thyroid cancer, or
benign thyroid disease trigger abrupt hair loss among
patients. Hair loss is perhaps the worst symptom of a
thyroid disorder. A patient with such disorder may also
experience excessive hair thinning, hair loss in vast
quantities together with the complete degradation of the
hair quality.
Experts cannot tell specifically how patients with thyroid
issues lose their hair. The patterns dont seem to be
specific. Others though link it to the hormonal activity in
the thyroid glands since it affects the metabolism of the
body and particularly the hair follicles.
Thyroid-Related Hair Loss
4. Another assumption is that the stressful
impact of thyroid problems to the body. As
believed, any form of severe stressor disturbs
the hair growth cycle, thus hastening and
prolonging the telogen phase, stage wherein
the hair shed off. Thus, it is said, thyroid
disorder leads to telogen effluvium as well.
Normally, at most 10% of the scalp hair
undergo telogen phase at any one time.
Hair loss doesnt only occur in the scalp but
also affects the rest of the follicles in the body.
Hypothyroidism, for example, may affect the
eyebrows as well.
Medications used to treat thyroid disorders are
also believed to cause hair loss. Two of the
most common medications that is believed to
cause hair loss are levothyroxine and
propylthiouracil. Still, how these medications
have an effect on hair growth remain unclear.
