Hair fall is a widespread concern. Among these, thyroid disorders are critical as they significantly impact various bodily functions, including hair health. The thyroid gland’s role is profound, regulating not only the metabolic rate but also affecting the skin, nails, and hair.


An underactive gland (hypothyroidism) or an overactive one (hyperthyroidism) can disrupt hair follicles by altering the hair growth cycle, leading to noticeable thinning and loss across the scalp.

These hormonal imbalances are pivotal because thyroid hormones are integral to the regeneration of hair follicles. In cases of hypothyroidism, the reduction in hormone production can slow hair growth, weaken follicles, and, in severe cases, cause diffuse hair loss.

Conversely, hyperthyroidism might result in hair becoming fine and sparse. This form of hair loss can be gradual making it difficult to detect until substantial hair has been lost.

However, the impact of thyroid disorders on hair is generally reversible with appropriate treatment. Thyroid hormone replacement or therapy to stop thyroid excess, can help stabilize hormone levels, allowing hair follicles to recover and hair growth to resume. Given the potential for reversibility.


A simple blood test can confirm the function of the thyroid gland. Raising awareness about the link between hypothyroidism, hyperthyroidism, and hair loss is vital. Early diagnosis and treatment can alleviate the hair loss and other symptoms associated with thyroid disorders.

For those experiencing hair loss without a clear cause, considering thyroid health as a potential factor is a proactive step. symptoms of thyroid imbalances—such as changes in weight, energy levels, and body temperature, alongside alterations in hair quality, warrants testing and treatment.

By integrating thyroid health into routine medical evaluations for patients reporting hair loss, we can significantly improve outcomes for individuals impacted by these conditions.
