When to see a doctor
Consult a healthcare professional if:
- The itching lasts more than 2–4 weeks despite home treatment.
- You notice severe redness, swelling, pain, or pus.
- You have significant hair loss or bald patches.
- You suspect a fungal infection or head lice.
- The itching is severe enough to disturb your sleep or daily activities.
Identifying the underlying cause is the key to choosing the right treatment, so persistent or severe symptoms should be evaluated by a healthcare provider.
