Does Thyroid Cause Hair Loss?

Hair loss can be a distressing experience, impacting self-esteem and overall well-being. While many factors contribute to hair loss, thyroid issues are a significant but often overlooked cause. Understanding the link between thyroid disorders and hair health is crucial for anyone experiencing unexplained hair thinning or loss.

What is the Role of Thyroid in Human Body?

The thyroid gland, a small butterfly-shaped organ located at the base of your neck, plays a critical role in regulating your body's metabolism through the production of hormones. These hormones, thyroxine (T4) and triiodothyronine (T3) influence many bodily functions, including heart rate, body temperature, and the rate at which your body uses energy.

Thyroid Types

Thyroid disorders can be broadly classified into two categories: hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid). Both conditions can lead to hair loss, although through different mechanisms.

1. Hypothyroidism

This condition occurs when the thyroid gland doesn't produce enough hormones. Common symptoms include fatigue, weight gain, and depression, but hair loss is also a notable sign. The lack of thyroid hormones can slow down the hair growth cycle, making hair thin, brittle, and prone to falling out.

2. Hyperthyroidism

On the other hand, It involves the overproduction of thyroid hormones. This condition speeds up metabolism and can cause symptoms such as weight loss, rapid heartbeat, and anxiety. Hair loss in hyperthyroidism happens because accelerated metabolism can prematurely push hair follicles into the resting (telogen) phase, leading to thinning hair and increased shedding.

How Thyroid Hormones Impact Hair Growth?

Hair growth occurs in cycles that include a growth phase (anagen), a transitional phase (catagen), and a resting phase (telogen). Thyroid hormones are essential for maintaining the normal duration of these phases. When thyroid levels are imbalanced, the hair growth cycle can be disrupted, leading to a condition called telogen effluvium, where a large number of hairs enter the resting phase and subsequently fall out.

Can We Identify Hair Loss Linked with Thyroid?

It might be difficult to differentiate thyroid-related hair loss from other forms of thinning hair, such as androgenetic alopecia (pattern baldness) or stress-induced shedding. Still, some indicators can help differentiate thyroid-related hair loss from other types:

Diffuse Thinning: Hair loss tends to be diffuse, meaning it occurs evenly across the scalp rather than in patches.

Changes in Hair Texture: The hair may become dry, coarse, and brittle with hypothyroidism or finer and softer with hyperthyroidism.

Related Symptoms: Look for other symptoms of thyroid disorders, such as changes in weight, energy levels, and mood.

Diagnosing and Treating Thyroid-Related Hair Loss:

It is essential to speak with a physician if you believe your thyroid issue is the cause of your hair loss. Usually, they will perform a physical examination and prescribe blood tests to check thyroid-stimulating hormone (TSH) and thyroid hormones (T3 and T4) levels.

Once a thyroid disorder is diagnosed, treatment involves restoring thyroid hormone levels to their normal range. For hypothyroidism, this usually means taking synthetic thyroid hormone (levothyroxine). For hyperthyroidism, treatment options may include anti-thyroid medications, radioactive iodine, or surgery.

As hormone levels stabilise, hair loss often slows, and normal hair growth resumes. However, it can take several months for hair to return to its previous thickness and health, as hair growth cycles take time to normalise.

Supporting Hair Health During Treatment

While managing your thyroid condition is crucial, there are additional steps you can take to support hair health during this period. Nutrition plays a key role in maintaining healthy hair. Ensure your diet is rich in essential vitamins and minerals, such as:

  • Iron: A low iron level might make hair loss worse.
  • Zinc: Important for hair tissue growth and repair.
  • Vitamin D: Helps create new hair follicles.
  • Biotin: B vitamin that is particularly beneficial for hair health.

The Role of Biotin in Hair Health

Biotin, also known as Vitamin B7, is an essential nutrient that supports the health of hair, skin, and nails. It helps strengthen hair strands, promotes hair growth, and prevents hair thinning. For those experiencing thyroid-related hair loss, biotin supplements can provide an additional boost to hair health.

One highly recommended supplement is ForMen Advanced Biotin 10,000mcg. These biotin tablets are formulated by experts and have the right doses and ingredients. They are specifically formulated to reduce hair fall and strengthen hair from within. Incorporating ForMen Biotin Tablets into your daily regimen supports your hair's health and helps strengthen your nails.


Practical Tips for Managing Hair Loss

Here are some practical tips to manage and minimise hair loss while dealing with a thyroid disorder:

  • Gentle Hair Care: Use mild, sulfate-free shampoos and conditioners to avoid irritating the scalp. Be gentle when brushing or styling your hair to prevent breakage.
  • Regular Scalp Massage: Stimulates blood flow to the hair follicles, promoting healthy hair growth.
  • Avoid Heat Styling: Limit the use of heat-styling tools like blow dryers and straighteners, as they can further damage fragile hair.
  • Stay Hydrated: Drink plenty of water to keep your scalp and hair hydrated.

Thyroid disorders are a common but often overlooked cause of hair loss. Both hypothyroidism and hyperthyroidism can disrupt the hair growth cycle, leading to diffuse thinning and increased shedding. You can effectively manage thyroid-related hair loss by recognizing the signs and seeking appropriate treatment.

In addition to medical treatment, supporting your hair health with proper nutrition and supplements like ForMen biotin tablets can make a significant difference. Hair growth takes time, so be patient and consistent with your care regimen. You can regain healthy, strong hair and improve your overall well-being with the right approach.
