Is it harmful to the scalp to remove the thick build up of scales by scratching and rubbing it off?
The scalp should be treated first and then rinsing them with any antifungal aromatherapy, such as lavender and tea tree oil. To remove by scratching will cause bacteria and infections and this will make conditions worse. If it itches, apply vinegar or tea tree oil and lavender. The itch will be gone in minutes.
