Thyroid disorders, such as hypothyroidism and hyperthyroidism, can significantly impact various aspects of health, including hair growth. Hair loss associated with thyroid issues can be distressing and often differs in appearance from other types of hair loss. This article explores the characteristics of thyroid-related hair loss, how to identify it, and what steps can be taken to manage it.

The thyroid gland produces hormones that regulate metabolism, energy levels, and the health of hair, skin, and nails. When the thyroid is underactive (hypothyroidism) or overactive (hyperthyroidism), it can disrupt the normal hair growth cycle, leading to hair loss.
1. Diffuse Thinning
- Appearance: One of the most common signs of thyroid-related hair loss is diffuse thinning, where hair loss occurs evenly across the entire scalp rather than in specific areas.
- Symptoms: Individuals may notice a general reduction in hair volume and density. The hair may appear finer, and the scalp may become more visible.
2. Brittle and Dry Hair
- Appearance: Hair affected by thyroid disorders often becomes brittle, dry, and more prone to breakage.
- Symptoms: The texture of the hair changes, making it feel coarse or straw-like. This is more common in hypothyroidism, where the metabolism slows down, affecting the health and moisture of the hair.
3. Hair Loss on the Eyebrows
- Appearance: A distinctive sign of thyroid-related hair loss, particularly in hypothyroidism, is the thinning or loss of hair on the outer third of the eyebrows.
- Symptoms: This specific pattern of hair loss, known as "Hertoghe's sign," can be a strong indicator of thyroid dysfunction.
4. Patchy Hair Loss
- Appearance: While less common, some individuals with thyroid disorders may experience patchy hair loss, similar to alopecia areata, where small, round bald spots appear on the scalp.
- Symptoms: These patches can be sudden and may occur alongside other autoimmune conditions, which are sometimes associated with thyroid problems.
5. Slow Hair Regrowth
- Appearance: In addition to hair loss, people with thyroid disorders may notice that their hair grows back more slowly than usual.
- Symptoms: Even after treatment, the hair may take a long time to regain its former thickness and length.
Identifying Thyroid-Related Hair Loss
To determine whether hair loss is related to a thyroid condition, it is essential to look for other symptoms of thyroid dysfunction, such as:
- Fatigue: Persistent tiredness that doesn't improve with rest.
- Weight Changes: Unexplained weight gain (hypothyroidism) or weight loss (hyperthyroidism).
- Mood Swings: Depression, anxiety, or irritability.
- Skin Changes: Dry, flaky skin or excessive sweating.
- Temperature Sensitivity: Feeling unusually cold or hot.
If these symptoms accompany hair loss, it's crucial to seek medical advice and undergo a thyroid function test.
Managing Thyroid-Related Hair Loss
- The primary step in addressing thyroid-related hair loss is managing the underlying thyroid disorder. This typically involves medication to normalize thyroid hormone levels.
- For hypothyroidism, synthetic thyroid hormones like levothyroxine are commonly prescribed. For hyperthyroidism, treatment may include antithyroid medications, radioactive iodine, or surgery.
- Ensure a balanced diet rich in essential nutrients that support hair health, such as iron, zinc, selenium, and vitamins A, D, and E.
- Consider supplements like biotin and omega-3 fatty acids, but always consult with a healthcare provider before starting any new supplements.
- Use gentle hair care products and avoid harsh treatments that can exacerbate hair breakage.
- Regularly trim split ends and avoid excessive heat styling to reduce further damage.
4. Patience and Monitoring
- Hair regrowth can take time, even after thyroid levels are normalized. Regular monitoring and follow-ups with a healthcare provider are essential to track progress.
- Conclusion
Thyroid-related hair loss often manifests as diffuse thinning across the scalp, brittle and dry hair, eyebrow thinning, and in some cases, patchy hair loss. Recognizing these signs and seeking appropriate treatment for the underlying thyroid condition can help manage and eventually reverse the hair loss. With proper care and medical attention, it is possible to restore hair health and prevent further loss.
