What are the benefits of using saline solution to wash hair for patients with scalp ringworm?

Washing the hair with saline solution can provide several benefits for patients with tinea capitis, including assisting in scalp cleansing, inhibiting fungal growth, relieving scalp itching, reducing dandruff, and alleviating inflammatory redness and swelling. It may serve as a supportive care measure alongside standard medical treatment. If the affected area expands, pus develops, or hair loss worsens, prompt medical attention is recommended.

1. Assists in scalp cleansing: The osmotic pressure of saline helps remove dirt, excess oil, and fungal metabolic byproducts from the scalp surface, reducing pathogen residue. This creates a cleaner environment for subsequent medication application and enhances treatment effectiveness.

2. Inhibits fungal growth: The hypertonic environment created by saline disrupts the survival conditions of fungi, suppresses the activity of certain pathogens, reduces fungal invasion of the scalp, and alleviates discomfort caused by tinea capitis.

3. Reduces scalp itching: Saline gently soothes irritated scalp nerves, reducing itchiness. This helps prevent scratching that could damage the scalp, lowers the risk of secondary infection, and protects the scalp’s natural barrier.

4. Decreases scalp flaking: Tinea capitis often causes abnormal shedding of the scalp's keratin layer. Saline can help soften keratin, reduce flaking, and clean away shed scales, keeping the scalp fresh and improving its appearance.

5. Alleviates inflammation and redness: For mild inflammation associated with tinea capitis, the gentle astringent effect of saline can help reduce redness and swelling, ease local inflammatory responses, and assist in controlling disease progression.

When washing the hair, use a mild saline solution to avoid irritation from excessive concentration. Maintain water temperature around 38°C, thoroughly rinse with clean water afterward, and follow up with a gentle, non-irritating shampoo. Keep the scalp dry and clean, and maintain regular sleep patterns to strengthen immunity.
