He's recently gotten really dry, flaky scalp and he has i guess cut marks on his scalp from his fingernails. I try to keep his nails short to stop that. But don't feel there really healing. Talked with his doctor at his 2yr appt we have him on tea tree oil for his skin she said can use it for his scalp as well and not to wash his hair a lot if we do. We don't wash(shampoo) that much to dry it out and i use the oil. I'm thinking of adding a coconut cream for his head. But is there anything else i could use or do to help his scalp?
