Generally speaking, flaky scalp may be caused by factors such as dry scalp, improper cleansing, excessive stress, seborrheic dermatitis, or psoriasis. If discomfort occurs, it is recommended to seek medical attention promptly. Specific analysis is as follows:
1. Dry Scalp
Dry climate or exposure to high heat from hair dryers can cause scalp dryness, leading to flaking and shedding of the scalp in patches. It is recommended to maintain proper moisture, use the cool setting on a hair dryer to dry hair, or gently pat hair dry with a towel.
2. Improper Cleansing
Excessive shampooing or scalp care can disrupt the natural oil balance of the scalp, causing overproduction of sebum, which may adhere to the scalp and form clumped dandruff. It is recommended to wash and cleanse the scalp 2–3 times per week.
3. Excessive Stress
High stress levels are often associated with anxiety, insomnia, and emotional tension. Stress can stimulate excessive sebum production on the scalp, resulting in increased dandruff. In daily life, it's important to regulate sleep patterns and engage in stress-reducing activities such as meditation or yoga to relax.
4. Seborrheic Dermatitis
This condition has multiple causes, including chronic lack of sleep, genetic predisposition, hormonal imbalances, and fungal infections. Patients often experience excessive sebum secretion, which irritates the scalp and leads to patchy dandruff, along with symptoms such as itching and redness. Treatment may include topical medications such as tacrolimus ointment, zinc oxide ointment, or compound ketoconazole cream, used under medical supervision.
5. Psoriasis
Psoriasis is commonly linked to scalp injury, family genetics, immune system dysfunction, respiratory infections, and obesity. It causes excessive proliferation of scalp keratinocytes, resulting in scaly, patchy dandruff, and may also be accompanied by symptoms such as stinging or burning sensations. Treatment should be guided by a physician and may include medications such as acitretin capsules, amoxicillin capsules, or compound acetic acid dexamethasone ointment.
In daily life, it is advisable to choose mild shampoos, clean the scalp appropriately, maintain healthy lifestyle habits, avoid staying up late, manage stress, and protect scalp health to prevent increased dandruff formation and shedding.
