Thyroid and Hair Loss: What You Need to Know

Hair loss can be distressing, especially when it happens suddenly or in
large amounts. While many factors contribute to hair fall, one often-overlooked
cause is thyroid imbalance. Your thyroid gland plays a key role in
regulating hormones, metabolism, and overall body function and when it doesn’t
work properly; your hair can show the effects.

The Thyroid–Hair Connection

The thyroid gland produces hormones (T3 and T4) that regulate cell
growth and energy production. Since hair follicles are highly sensitive to
hormonal changes, thyroid dysfunction can disrupt the natural growth cycle of
hair.

• Hypothyroidism (underactive thyroid): Can cause dry, brittle hair and thinning across the scalp,
  eyebrows, and even body hair.


• Hyperthyroidism (overactive thyroid): May lead to excessive shedding and fine, fragile hair.

Signs of Thyroid-Related Hair Loss

If your hair fall is due to thyroid problems, it’s usually accompanied
by other symptoms, such as:

• Unexplained weight changes


• Fatigue or low energy


• Dry skin or brittle nails


• Feeling unusually hot or cold


• Menstrual irregularities in women


• Anxiety, irritability, or mood swings

Can Thyroid Hair Loss Be Reversed?

Yes, in most cases! Once the underlying thyroid condition is diagnosed
and treated, hair growth usually improves. However, it can take several
months for noticeable results since hair regrowth is a slow process.

Management & Treatment Tips

• Medical treatment: Proper
  thyroid medication prescribed by an endocrinologist.


• Nutrition: A diet rich in protein, iron, selenium, and
  zinc supports hair health.


• Vitamin D & Biotin: Helpful
  supplements if you have deficiencies.


• Stress management: Stress can
  worsen both thyroid issues and hair loss.


• Avoid harsh hair treatments: Reduce
  chemical exposure and heat styling to prevent further damage.

When to See a
Doctor

If you’re experiencing persistent hair loss along with symptoms of
thyroid imbalance, don’t ignore it. Early diagnosis and treatment by an Endocrinologist
can prevent further complications and restore your health and confidence.

Remember: Hair loss is often
a symptom, not the disease itself. By treating the root cause your thyroid you
can regain both your health and your hair.
