Small, butterfly-shaped thyroid glands in the neck regulate metabolism, energy, and hair growth. A thyroid imbalance (hypothyroidism or hyperthyroidism) can disrupt the hair growth cycle, causing thinning, excessive shedding, and hair loss. Approximately 200 million people worldwide suffer from thyroid disorders, with women being five to eight times more likely to develop thyroid conditions than men, states a study by WHO and American Thyroid Association (ATA). Thyroid imbalances can lead to various side effects, including weight fluctuations, fatigue, mood changes, and hair loss.

The good news is that thyroid-related hair loss can often be reversed with proper diagnosis and treatment. While thyroid-related hair loss can be alarming, the good news is that it is often reversible with proper diagnosis and treatment. This blog will teach how thyroid affects hair health, symptoms to watch for, and effective treatment options.

How Does Thyroid Affect Hair Growth?

Thyroid disorders impact hair health due to hormonal imbalances.

  • Hypothyroidism (Underactive Thyroid): Leads to diffuse hair thinning, dryness, and brittle strands.
  • Hyperthyroidism (Overactive Thyroid): Causes scalp irritation and rapid hair shedding.

Increasing hair fall is caused by both conditions disrupting the hair growth cycle, pushing more follicles into resting (telogen) phases.

Signs and Symptoms of Thyroid-Related Hair Loss

Thyroid Hair Thinning Symptoms:

  • Coarse, dry hair texture : More susceptible to breakage.
  • Diffuse hair loss : Can lead to thinning all over the scalp instead of bald patches.
  • Loss of body hair : Affects eyebrows, eyelashes, armpits, and pubic hair.

Other Signs of Thyroid Dysfunction:

  • Weight fluctuations (Sudden weight gain or loss).
  • Difficult to concentrate, Fatigue, and weakness
  • Sensitivity to cold (hypothyroidism) or heat (hyperthyroidism).
  • Dry skin and Brittle nails.

Can Thyroid Hair Loss Be Reversed?

  • Yes, thyroid-related hair loss is often reversible once hormone levels are stabilised.
  • Treatment takes time – hair regrowth may take 3-6 months after starting thyroid therapy.
  • Hair care, proper nutrition and homeopathy together can speed up regrowth.

Diagnosis and Treatment for Thyroid-Related Hair Loss

Doctors diagnose thyroid disorders through blood tests measuring:

  • Thyroid-Stimulating Hormone (TSH)
  • T3 (Triiodothyronine) & T4 (Thyroxine) levels

Conventional Treatments:

  • Hypothyroidism Treatment: Levothyroxine (Synthetic Thyroid Hormone) restores normal levels.
  • Hyperthyroidism Treatment: Antithyroid drugs, radioactive iodine therapy, or surgery.
  • Conventional treatments may have certain side-effects.

Ignoring thyroid problems can worsen hair loss and overall health, so early treatment is crucial.

How to Stop Hair Loss from Thyroid?

  • Follow your thyroid treatment plan diligently.
  • Eat a nutrient-rich diet with iron, biotin, and Omega-3s.
  • Reduces stress through yoga, meditation, and exercise.
  • Prevent scalp irritation by using gentle and sulphate-free shampoo.

Lifestyle Changes to Promote Hair Regrowth

  • Nutritional Support: Eat foods rich in Vitamin D, Iron, and Zinc.
  • Hydration: Drink 8-10 glasses of water daily for scalp health.
  • Avoid Harsh Hair Treatments: Reduce heat styling and chemical treatments.
  • Scalp Massage: Stimulates blood circulation and hair growth.
