What causes thick and abundant hair?
Excessive body hair growth may result from endocrine disorders, genetic factors, long-term medication use, or gynecological conditions.
1. Endocrine Disorders
Excessive androgen secretion is the primary cause of increased hair growth.
2. Genetic Factors
Individuals whose parents have abundant body hair may inherit this trait, resulting in notably excessive body hair.
3. Long-Term Medication Use
Some patients taking glucocorticoid-containing medications over extended periods may experience increased hair growth, as glucocorticoids can stimulate hair follicles. For example, patients with chronic glomerulonephritis or allergic purpura who receive prolonged glucocorticoid therapy often develop marked hirsutism.
4. Gynecological Conditions
Patients with polycystic ovary syndrome (PCOS) frequently present with hirsutism—excessively dense, coarse, and abundant body hair.
Therefore, individuals experiencing excessive body hair should consult a qualified healthcare provider at an accredited medical institution and undergo appropriate laboratory testing, as guided by their physician, to inform clinical management.
