there are many causes for itchy scalps but dry skin would be high on the list as well as chemical sensitivity reactions (to shampoo) fungal scalp infections and yes even head lice. it is not possible to determine a specific cause based on itching alone. he will need to see a medical provider or dermatologist for a proper examination but in the meantime he can try some medicated over-the-counter shampoo used for dry scalp conditions to see if it helps. a pharmacist can help him chose a proper one.
the back of my head itches and is starting to have hair loss but baldness does not run in my family. what is the cause?
