Olaiya explains how he treats his mental illness patients He says the head of the patient will be scraped before treatment commences. After we scrap the hair, we would apply a medicine to the head and we would tie it up, or we use a cap to cover it. The medicine will then pass through the scalp into the head and would work on the head (brain). It is not blade at all, we don’t use blade for scraping. so when the medicine get into his head, it would operate on the head to a normal way before the person can now starts to use other medication for healing.
