I did this many many yearssssssss back. It gave me miagrines. My scalp was dandruff free, but the miagrines were insufferable (I hardly ever get headaches or migraines). Soon a weird film was on my scalp so I stopped. I didnt stick with it long enough to notice hair growth. Currently, I've started exfoliating with sea salt and my scalp looks similar without the migraines and no weird film.
