Hello, im having all the same issues with hair and scalp. I was mixing borax and extra virgin olive oil in a thick paste and rubbing all over into scalp and leave in all afternoon, feels really good and seems to help if done once or twice a week. I did just recently find another post with a home remedy I have yet to try. Apparently alfalfa, borax, and a few essential oils (tea tree, peppermint and what ever else you like) in a hot bath will completely kill all of them for good. Im going to try just soaking my head under the water for a little while and see what happens. I will let you know what happens. I hope I helped.
