Introduction
Excessive hair growth may result from either physiological or pathological factors.
1. Physiological factors: Individuals with adequate nutrition and robust physical constitution—particularly those whose parents both have abundant hair—may inherit this trait genetically, representing a normal physiological phenomenon.
2. Pathological factors: Excessive hair growth can also be associated with certain pathological conditions.
Excessive hair growth may result from either physiological or pathological factors, and the underlying cause can be determined through appropriate medical evaluations.
1. Physiological factors: Hair is a relatively important tissue in the human body. Individuals with adequate nutrition and robust physical constitution may experience faster hair growth or increased hair density. Genetic inheritance also plays a role—children may inherit thick or abundant hair from one or both parents. Additionally, increased hair volume may occur naturally with aging; this is considered a normal physiological phenomenon. Routine scalp hygiene is essential—regular washing with warm water is recommended.
2. Pathological factors: Excessive hair growth can also be associated with certain pathological conditions. Prolonged use of hormonal medications, or chronic unhealthy dietary and lifestyle habits, may disrupt endocrine function, leading to abnormal hormone secretion. Specifically, elevated androgen levels may cause hirsutism (excessive terminal hair growth) or increased scalp hair density. Prompt evaluation at a reputable hospital is advised. A comprehensive “six-hormone panel” test can accurately assess systemic hormone levels and identify the cause of excessive hair growth. If hormonal imbalances are confirmed, oral hormonal therapy may be required.
