3. Impetigo Explained
Caused by Staphylococcus aureus or Streptococcus pyogenes, impetigo begins as red blisters or sores that quickly burst, leaving thick golden-yellow crusts. It spreads easily in warm, humid conditions and through skin-to-skin contact. Although children are most at risk, adults with skin cuts, scrapes, or abrasions are also vulnerable to infection.
4. Symptoms That Need Attention
- Beyond the visible crust, watch for additional war:ning signs such as redness, swelling, itching, pain, or spreading lesions.
- Systemic symptoms like fever, swollen lymph nodes, or fatigue suggest the infection may be advancing and require prompt medical care.
5. When Professional Care Is Necessary
Mild scalp irritations can often be handled at home, but seek medical help if:
- The crust doesn’t improve after a week.
- The area shows signs of worsening infection (increasing redness, warmth, swelling, or pus).
6. Home-Based Relief
While waiting for treatment, some home measures may ease symptoms:
- Apply a warm, damp cloth to soften crusts and calm irritation.
- Wash with a gentle, fragrance-free shampoo to maintain scalp cleanliness.
- Try diluted tea tree oil for its antimicrobial properties (patch test first).
- Use coconut oil to moisturize and soothe dryness.
7. Over-the-Counter Options
Several OTC products may help:
- Anti-dandruff shampoos with zinc pyrithione, selenium sulfide, or ketoconazole for seborrheic dermatitis or mild fungal issues.
- Topical antibiotic creams (e.g., bacitracin, neomycin) for suspected bacterial causes.
- Hydrocortisone cream to reduce itching and inflammation, but only in moderation and ideally under guidance.
