Thyroid Disorders and Hair Loss: What You Need to Know

Understanding the Thyroid Gland
The thyroid gland produces hormones, primarily thyroxine (T4) and triiodothyronine (T3), that regulate metabolism, growth, and energy levels. These hormones are essential for maintaining healthy hair growth. When the thyroid gland produces too little or too much of these hormones, it can disrupt the hair growth cycle and lead to hair loss.

Types of Thyroid Disorders Linked to Hair Loss
1. Hypothyroidism (Underactive Thyroid):

Causes: When the thyroid gland doesn't produce enough thyroid hormone.

Impact on Hair: Hypothyroidism can cause hair follicles to become less active, leading to thinning and loss of hair.

2. Hyperthyroidism (Overactive Thyroid):

Causes: When the thyroid gland produces too much thyroid hormone.

Impact on Hair: Hyperthyroidism can accelerate the hair growth cycle, causing hair to become thin and brittle.

3. Autoimmune Disorders:

Hashimoto's Thyroiditis: An autoimmune condition that can lead to hypothyroidism.

Graves' Disease: An autoimmune condition that can lead to hyperthyroidism.
