Hair loss can cause us many troubles, not only affecting our life and work, but also bringing us significant mental stress. So, what are the general causes of hair loss? 1. Endocrine disorders: Hair growth is affected by various hormonal influences. The pressure from routine work, life, and studies can cause disruptions in physical functions, as well as conditions like postpartum and menopause, leading to endocrine disorders. 2. Nutritional deficiencies: Nutritional deficiencies and abnormal metabolism can lead to hair loss, with severe malnutrition even causing diffuse hair loss. 3. Genetic factors: Typically, males are more prone to hair loss due to genetic traits that manifest under the influence of androgens. 4. Physical illness: Some medications taken for diseases can cause side effects, including hair loss. 5. Physical and chemical hair loss: Frequent perming and hair dyeing, long hours in front of computers, and frequent use of mobile phones can all lead to hair loss.
