A key factor causing dandruff is the parasitic Malassezia fungus. This fungus is a normal resident on human skin, feeding on sebum. When it proliferates excessively, it can lead to dandruff, making individuals with oily scalps more prone to this condition. Mental Tension and Anxiety Numerous complex factors contribute to dandruff formation, often linked to the excessive pressures and fast pace of modern life.
The human body is a complex organic system. Mental stress and anxiety can disrupt internal balance, affecting scalp health. To alleviate anxiety and tension, consider practicing yoga or similar activities to regulate emotions. Strive to maintain a stable, relaxed mental state and keep your mood calm.
Insufficient Sleep
Adequate sleep promotes normal skin metabolism.Traditional wisdom advocates sleeping during the "midday and midnight hours." Young people today should avoid staying up late whenever possible, ideally going to bed before 11 PM. Adequate sleep can alleviate dandruff symptoms.
Spicy Foods, Excessive Smoking and Drinking
Consuming spicy foods and indulging in excessive smoking and drinking can impair nutrient absorption. Once absorbed, harmful substances further disrupt bodily metabolism.Therefore, focus on balanced nutrition: regularly consume protein-rich foods and trace elements, eat more vegetables and fruits, and limit greasy or high-sugar foods. Physical Discomfort When feeling unwell—such as with gastrointestinal issues, nutritional imbalances, or endocrine disorders—the body often experiences hormonal changes that can increase dandruff.
Shampoo Allergies
Some individuals notice dandruff and itching when using certain shampoos, which improves when switching brands. This may indicate a shampoo allergy. Additionally, many hair care products like hair dyes, hairsprays, and mousses can cause contact dermatitis on the scalp.
