Introduction
Seborrheic alopecia refers to androgenetic alopecia. In general, the occurrence of small itchy bumps on the scalp in patients with androgenetic alopecia may be related to excessive scratching, over-cleansing, folliculitis, eczema, or tinea capitis, among other causes. Treatment may involve lifestyle adjustments and medication. Patients should seek appropriate treatment under the guidance of a physician based on their individual condition.

Seborrheic alopecia refers to androgenetic alopecia. In general, the occurrence of itchy small bumps on the scalp in patients with androgenetic alopecia may be related to excessive scratching, over-cleansing, folliculitis, eczema, tinea capitis, and other causes. Treatment may involve lifestyle adjustments and medication. Specific details are as follows:

1. Excessive scratching: Itching often leads to excessive scratching, which further irritates the scalp and may worsen itching and cause skin damage, resulting in small bumps. Excessive scratching may also lead to skin breaks and infections. Patients should avoid excessive scratching and maintain good scalp hygiene.

2. Over-cleansing: Using too much or harsh shampoo products and washing the hair and scalp too frequently can lead to excessive dryness and irritation of the scalp. This makes the scalp more prone to itching and irritation, potentially causing the aforementioned symptoms. It is recommended to switch to a mild shampoo and maintain a moderate cleansing frequency.

3. Folliculitis: Folliculitis is an inflammatory reaction around hair follicles caused by bacterial infection. Hair follicles in patients with androgenetic alopecia are particularly susceptible to inflammation, which may lead to folliculitis and result in itching and small bumps. Follow medical advice to use medications such as mupirocin ointment or fusidic acid sodium ointment to relieve symptoms.

4. Eczema: Eczema is a common inflammatory skin condition characterized by redness, itching, and small bumps on the scalp. It may be associated with abnormal immune responses and can also occur in patients with androgenetic alopecia. Treatment under a doctor's guidance may include topical corticosteroids such as desonide cream or hydrocortisone cream.

5. Tinea capitis: Tinea capitis is a fungal infection commonly presenting as red patches, scaling, itching, and small bumps on the scalp. It often coexists with androgenetic alopecia. Under medical supervision, antifungal creams such as clotrimazole cream or ketoconazole cream may be used to alleviate discomfort.

Patients should seek symptomatic treatment under the guidance of a healthcare professional based on their individual conditions.
