How to Soothe the Itch:
If your condition is widespread you should make an appointment with your doctor or dermatologist immediately. In serious cases you may need an antibiotic or anti-fungal medicine to control the condition.
For less severe cases you can try the following at home remedies:
Warm Compress: Apply a warm compress to your scalp a few times a day to soothe the scalp and help drain pus.
Medicated Shampoos: Use a medicated shampoo that has anti-fungal properties. For example, these may include ketoconazole, ciclopirox or shampoos infused with tea tree oils.
Cortisone Cream: Depending on your doctor’s recommendation, you could apply a cortisone cream. Apply it to the affected area which could help treat and relieve some of your symptoms.
Wash More Often: Wash your combs, brushes and bed linens and tools or clothing that may have come into contact with your scalp.
But if your scalp is hurting, this may be why.
