I tried it and at first I probably didn’t scrub my scalp enough (my hair was also longer) so dandruff was the only problem I had so I went back to ivory soap. Weeks later I got a buzzer and keep my hair at 5/8ths inch once a month then did ivory only every other night a couple weeks before dropping it altogether. Now I only use a really natural shampoo after a haircut to get the clippings out. Never had problems with oil. Just keeping my hair short and well scrubbed keeps the dandruff down.
