I don't know about itch, but something in the big three or head & shoulders has cleared up my head sores. Off and on for years I've had sparse acne like sores on my scalp. Within a couple of weeks they were gone and have not come back.
minoxidil actually causing the itch for me, for some bizzar reason I have itching on the crown after applying the minoxidil despite I don't even put it on the crown
I think I benefited it the best I could since I did not have noticeable hair loss ... I also had itchy scalp after minoxidil, something I never experienced before. ... from using Minoxidil as well as help ensure the health of your scalp. instaflex
