Definitely follow up with ACV. Then finish off with a cold rinse dandruff is just dryness of the scalp and when washing your scalp with hot water it will make the problem worse. Try to wash every two days and use cold water. I rinse my scalp everyday because I am a workoutaholic lol. I just do a quick rinse in the shower after every work out and wash my dreads with shampoo. I do the bs/acv twice a month just to get that extra junk out, honestly I am amazed that the bs/acv rinse is not grotesque. Just do the cold water and it should help immensely.
