What should I do if my hair is extremely thick and dense?

Generally, having unusually thick and abundant hair may be caused by factors such as genetic predisposition, stable hormone levels, polycystic ovary syndrome (PCOS), adrenal cortical hyperplasia, or hypothyroidism. It is recommended to seek medical attention promptly, identify the underlying cause, and follow a doctor's guidance for improvement through general management, medication, or other treatments. A detailed analysis is as follows:

1. Genetic factors: A family history of thick hair often means a higher number of hair follicles and vigorous growth, resulting in heavy, dense hair. Layered haircuts can help reduce visual bulkiness. Using oil-control shampoo regularly can also minimize hair clumping.

2. Stable hormone levels: In adolescent or reproductive-aged women with normal estrogen levels, hair follicles receive adequate nutrition, leading to healthy, thick hair growth. No special treatment is required; regular haircuts can help manage hair volume, and avoiding excessively long hair can prevent added weight and strain.

3. Polycystic ovary syndrome (PCOS): Excessive secretion of androgens in the body stimulates excessive hair growth, causing thicker hair along with hirsutism. Patients may take medications such as ethinylestradiol cyproterone tablets, drospirenone-ethinyl estradiol tablets, or spironolactone tablets under medical supervision to regulate hormone levels.

4. Adrenal cortical hyperplasia: Abnormal adrenal function leads to overproduction of glucocorticoids, resulting in excessive hair growth and notably thicker hair. Patients should take medications such as hydrocortisone tablets, prednisone acetate tablets, or dexamethasone tablets as prescribed to control adrenal activity.

5. Hypothyroidism: Insufficient thyroid hormone secretion slows metabolism and prolongs the hair follicle growth cycle, causing hair to accumulate and appear thicker, often accompanied by dryness and brittleness. Patients may take levothyroxine sodium tablets, thyroid tablets, or levothyroxine sodium capsules as directed by a physician to supplement thyroid hormones.

During shampooing, gently massage the scalp with fingertips and avoid pulling or tugging on the hair. Use a wide-toothed comb to detangle hair and minimize breakage. Maintain a light diet, reduce intake of high-fat and high-sugar foods, and adhere to regular sleep patterns to support stable endocrine function.
