Metabolic Rate and Hair Follicle Dynamics<\/h3>\r\n

The thyroid gland, located in our neck, is one of the most critical endocrine centers governing the body's overall energy production and metabolic rate. As detailed in the image above, insufficient secretion of thyroid hormones (hypothyroidism) slows down the hair cycle, trapping it in the resting phase, while excessive secretion (hyperthyroidism) accelerates the cycle, leading to widespread hair thinning. <\/p>\r\n <\/div>\r\n\r\n \r\n

What is the Connection Between Thyroid Hormones and Hair Health?<\/h4>\r\n

The butterfly-shaped thyroid gland in our neck controls our body's metabolic rate. The hormones it secretes directly affect the energy production, growth, and renewal cycle of hair follicles. <\/p>\r\n \r\n

Hypothyroidism (Underactive Thyroid) and Hair Loss<\/h4>\r\n

When thyroid hormones are insufficient, metabolism slows down. Hair follicles enter the resting phase prematurely; hair becomes dull, dry, brittle, and widespread shedding begins. Thinning may sometimes also be observed in the outer parts of the eyebrows. <\/p>\r\n \r\n

Hyperthyroidism (Overactive Thyroid) and Hair Loss<\/h4>\r\n

Excessive secretion of thyroid hormones, on the other hand, excessively speeds up metabolism. This disrupts the hair cycle, leading to thinning hair strands and diffuse hair loss. <\/p>\r\n \r\n

What Should Be Done?<\/h4>\r\n

In cases of unexplained, widespread hair loss, thyroid functions must be examined through blood tests (TSH, free T3, free T4). When thyroid treatment is regulated, the hair cycle gradually returns to normal. <\/p>\r\n <\/section>\r\n\r\n \r\n
