When to contact a professional
A dermatologist should be consulted for any itchy, hard, persistent lumps on the scalp.
Successful treatment can take time. While medical therapy can bring the condition under control, the chronic scratching and rubbing gets to be a habit so that behavior modification is required with a conscious effort made to leave the areas alone even when the itching has stopped. Relapses are common; stress and anxiety can make the condition worse.
