1. Observing hair loss patterns: Male type hair loss: usually starts from both sides of the forehead, with hair strands gradually receding, forming an "M" type of hair loss. The hair on the top of the head also gradually becomes sparse, and eventually only a circle of hair on the back and sides of the head may remain. Female type hair loss: mainly manifested as sparse hair at the top of the head, widened hairline, but the hairline on the forehead usually does not retract. Alopecia areata: Sudden appearance of circular or oval areas of hair loss on the scalp, with clear edges, smooth skin, and no inflammation or scars.
2. Analyze the causes of hair loss: Hereditary hair loss: There is a history of hair loss in the family, especially if parents or direct relatives have similar hair loss situations. Stress and anxiety: Recently experiencing major life changes, high work pressure, emotional anxiety, etc., may exacerbate hair loss. Malnutrition: Lack of protein, iron, zinc and other nutrients, or insufficient vitamin D and B vitamins, may affect hair growth. Drug side effects: Some drugs may cause hair loss. Disease related: autoimmune diseases such as thyroid disease, anemia, lupus erythematosus, etc., may be accompanied by hair loss symptoms.
3. Conduct professional testing: Skin microscopy examination: Observe the condition of the scalp and hair follicles through skin microscopy to help diagnose hair loss types and evaluate hair follicle health. Blood test: Check thyroid function, anemia indicators, etc., to rule out hair loss caused by diseases. Professional consultation: Consult a dermatologist or hair specialist for detailed assessment and recommendations based on individual circumstances.
