How to remove excessive dandruff, and what is the most effective method?

Generally, each person's scalp condition varies, and excessive dandruff may be caused by factors such as dry scalp, seborrheic dermatitis, psoriasis, tinea capitis, and others. Usually, targeted treatments can be conducted by improving hair-washing methods, adjusting lifestyle habits, and medication therapy. If symptoms are severe or persistent, timely medical consultation is recommended. Detailed analysis is as follows:

1. Dry Scalp: When the scalp lacks sufficient moisture and oil, the stratum corneum may peel off and form dandruff. It is recommended to improve hair-washing methods by using mild, moisturizing shampoo and conditioner, avoiding products with excessive alkalinity, and maintaining the scalp's moisture balance.

2. Poor Hair-Washing Habits: Unhealthy hair-washing habits such as washing hair too frequently, using excessively hot water, and vigorously scratching the scalp may damage the normal barrier function of the scalp and cause dandruff problems. It is recommended to adjust the frequency of shampooing, use appropriate water temperature, and gently massage the scalp to maintain scalp health.

3. Seborrheic Dermatitis: This condition is generally caused by genetic factors, infections, and other factors. When it occurs on the scalp, it causes excessive sebum secretion, leading to itching and dandruff, often accompanied by oily scalp, redness, and intensified itching. It is recommended to use medications such as tacrolimus ointment, pimecrolimus cream, and itraconazole capsules under a doctor's guidance.

4. Psoriasis: The pathogenesis of psoriasis is related to abnormal activation of the immune system. When it affects the scalp, it causes red patches covered with silvery-white scales. Symptoms may include scalp itching, flaking, and hair appearing in tufts. It is recommended to use medications such as methotrexate tablets, acitretin capsules, and calcipotriol ointment under a doctor's guidance.

5. Tinea Capitis: Tinea capitis is a skin disease caused by fungal infection of the scalp and hair. It causes round or irregular bald patches on the scalp covered with grayish-white scales. Accompanying symptoms may include scalp itching, pain, and hair loss. Medications such as griseofulvin tablets, econazole nitrate cream, and ketoconazole cream may be used as directed by a physician to alleviate symptoms.

In daily life, maintaining a healthy lifestyle is also important, including improving dietary habits, adjusting sleep schedules, enhancing physical fitness, and regulating body condition to reduce dandruff caused by physiological factors.
