Severe hair loss, which department should I visit at the hospital?

Generally, severe hair loss can be treated by visiting different departments such as dermatology, endocrinology, nutrition, gynecology, and psychosomatic medicine, depending on the specific situation. Detailed explanations are as follows:

1. Dermatology

Most hair loss problems are essentially caused by skin diseases related to the scalp and hair. For example, excessive sebum secretion from the scalp may cause inflammation, affecting follicle health and resulting in hair loss. Dermatologists can observe the scalp condition—such as presence of redness, scaling, or sebum secretion—and use tools like dermoscopy to examine microscopic features such as follicle morphology and hair shaft thickness, enabling accurate diagnosis and targeted treatment plans.

2. Endocrinology

If severe hair loss is caused by an endocrine system disorder, such as excessive thyroid hormone secretion, the body's metabolism accelerates and disrupts the normal hair growth cycle, causing premature hair shedding. In such cases, patients should visit the endocrinology department. Endocrinologists will test thyroid function, sex hormone levels, blood glucose, and other related endocrine indicators to identify the underlying cause, and then implement appropriate treatments to regulate the endocrine system and improve hair loss.

3. Nutrition

Severe hair loss can also result from deficiencies in essential nutrients. For example, insufficient protein intake leading to inadequate synthesis of keratin—the main component of hair—can make hair brittle and prone to breakage and shedding. Nutritionists will carefully evaluate daily dietary patterns and assess whether nutritional intake is balanced. Through tests such as complete blood count and trace element analysis, they can determine if nutritional deficiencies exist and provide dietary adjustment recommendations to improve hair loss conditions.

4. Gynecology

Women may experience significant hair loss during special physiological stages such as menstruation, pregnancy, and postpartum periods due to hormonal changes. For example, after childbirth, a sharp drop in estrogen levels can cause a large number of hairs in the growth phase to simultaneously enter the resting phase, leading to noticeable hair loss. Gynecologists will consider factors such as menstrual cycles and reproductive history, and, in combination with hormone level testing, determine whether the hair loss is caused by hormonal changes during these special physiological stages, and then provide appropriate调理 (regulating) advice.

5. Psychosomatic Medicine

Long-term mental stress, anxiety, depression, or excessive pressure can cause dysfunction of the nervous system, disrupting the normal hair growth cycle and leading to significant hair loss—referred to as psychogenic alopecia. Psychosomatic medicine specialists can use professional psychological assessment scales and detailed consultations to determine if psychological factors are responsible for the hair loss, and then apply psychological counseling, relaxation training, and other methods to help patients relieve mental stress.

In daily life, it is important to maintain adequate sleep, avoid excessive fatigue, consume more fresh vegetables and fruits such as cabbage, apples, and tomatoes, and enhance overall immunity.
