I can vouch for the essential oils. I had some dandruff issues prior to letting my hair dread and that was one of my concerns because I wouldn't be able to comb out the flakiness. I add the rosemary, tea tree and lavender to my wash and have not had any dandruff issues since! If you add some to your BS and your ACV rinse I'm certain you will see a difference.
Let us know how these changes work out for you.
