Introduction
Itchy scalp in autumn may be caused by non-medical factors such as excessively dry weather, or by medical conditions such as seborrheic dermatitis, urticaria, and psoriasis. Depending on the specific condition, general treatments or medications can be used to relieve symptoms. In daily life, reduce intake of spicy and other irritating foods to minimize scalp irritation. Also limit consumption of greasy foods to prevent excessive oil production on the scalp.
Scalp itching in autumn may be caused by non-disease factors such as excessively dry weather, or by medical conditions including seborrheic dermatitis, urticaria, and psoriasis. Depending on the specific condition, symptom relief can be achieved through general management, medications, or other treatments.
I. Non-disease Factors
1. Dry Weather
The dryness of autumn weather can lead to increased dandruff and scalp itching, which is a normal phenomenon. In such cases, using an effective anti-dandruff shampoo for washing the hair is sufficient. Avoid washing hair too frequently.
2. Temperature Changes
As temperatures drop in autumn, cold stimulation may cause scalp itching. This is a physiological response that typically does not require treatment and improves with proper warmth and protection.
II. Disease-related Factors
1. Seborrheic Dermatitis
Excessive oil production on the scalp, if not cleaned promptly, may trigger seborrheic dermatitis, leading to red rashes and itching. In such cases, treatment under medical guidance may include oral doxycycline hydrochloride capsules and vitamin B6 tablets, along with topical application of tacrolimus ointment as adjunct therapy. It is also important to maintain scalp cleanliness and use a shampoo with strong oil-removing properties.
2. Urticaria (Hives)
In autumn, exposure to cold air or using a new shampoo may trigger hives at the contact site, resulting in scalp itching. It is important to identify the allergen promptly, avoid re-exposure, or undergo desensitization treatment. Antihistamines such as levocetirizine tablets can be taken, and topical corticosteroid creams like hydrocortisone butyrate cream or fluticasone propionate cream may be applied to assist treatment.
3. Psoriasis
In patients with psoriasis, scalp scales are often thick, extend beyond the hairline, and may cause hair to clump together, accompanied by itching. Topical medications can be used to strengthen skin barrier protection. Commonly used agents include retinoids, vitamin D analogs, and calcineurin inhibitors. For more severe symptoms, systemic medications such as methotrexate or cyclosporine may be prescribed.
Additionally, other conditions such as folliculitis, contact dermatitis, and scabies may also cause similar symptoms. If symptoms persist or recur, timely medical evaluation and treatment under a physician’s guidance are recommended. Reducing intake of spicy and irritating foods can help minimize scalp irritation. Limiting oily foods helps prevent excessive scalp sebum production. Try to minimize the use of hair products containing alcohol. Maintain good skin hygiene, avoid scratching and washing with hot water, and wait until the hair roots are completely dry after washing before resting.
