soak your hair in apple cider vinegar for a couple of hours massage it in vigorously and wash it off with a mild shampoo .. the itching will stop permanently another remedy is rubbing in onion juice the small variety,, put the onion in a blender remove n sqeeze out the juice massage into head n leave for 3 or more hours and then wash ... its works like a miracle
I also recomend the apple cider vinegar. it stops the itching and restores the ph to your scapl and hair and gets rid of the grease. if your scalp is dry as well smash bananas (ripe ones) and put in your hair. it nursishes it.
I had ringworm once a long time ago and my uncle told me to use borax and it worked like a charm! My hubby suggested that I try it on my head, but I hadn't heard of anyone doing that...did it work well for you?
