Introduction
Dandruff accompanied by itching may be caused by dry skin, seasonal changes, seborrheic dermatitis, psoriasis, tinea capitis, or other reasons. If the above symptoms occur, it is recommended to visit a正规 hospital and receive treatments such as general therapy or medication under the guidance of a doctor. In daily life, maintain scalp cleanliness and avoid excessive cleansing or irritation.
In general, excessive dandruff accompanied by itching may be caused by factors such as dry skin, seasonal changes, seborrheic dermatitis, psoriasis, or tinea capitis. When the above conditions occur, it is recommended to visit a正规 hospital and seek treatments such as general care or medication under the guidance of a doctor. Specific analyses are as follows:
1. Dry Skin
Dryness and itching of the scalp, along with fine flakes, can result from low environmental humidity or over-cleansing. Specific medications are usually not required; daily use of moisturizing conditioners can help improve the condition.
2. Seasonal Changes
Changes in climate can affect the scalp's adaptability, leading to seasonal increases in dandruff. Appropriate shampoo and hair care products can be selected according to the season.
3. Seborrheic Dermatitis
Seborrheic dermatitis may be triggered by microbial infection, dietary habits, and other factors. Abnormal sebum secretion and fungal infections can lead to symptoms of excessive dandruff and itching. Symptoms may include oily scalp and red patches. Patients may use medications such as compound ketoconazole cream, tacrolimus ointment, or pimecrolimus cream as directed by a physician.
4. Psoriasis
Psoriasis is associated with genetic and immune system abnormalities. When psoriasis affects the scalp, it causes excessive dandruff and itching, often accompanied by red plaques and hair loss. Under medical guidance, patients may use medications such as desonide cream, urea cream, or calcitriol ointment to relieve symptoms.
5. Tinea Capitis (Scalp Ringworm)
Tinea capitis may be caused by fungal infection, hereditary factors, and others. It leads to round or irregular red patches on the scalp covered with grayish-white scales, accompanied by significant itching. Symptoms such as hair loss and papules may also occur. Patients need to use antifungal medications such as bifonazole cream or miconazole nitrate cream under a doctor’s advice.
In daily life, maintaining scalp cleanliness, avoiding excessive cleansing and irritation, ensuring balanced nutrition, and engaging in moderate exercise can help prevent and alleviate dandruff and itching.
