That could also be due to the oils. How much are you adding to your wash?
Hello! I saw your comment to Baba about waking up with damp hair. You should never sleep with wet or damp hair while dreading. That can easily be a factor in getting mold inside them.
Welcome. Do you have oily hair, normally? If not, then after you do the BS wash, and rinse it out well, you'll need to do an ACV rinse to reset your pH levels. Just the BS will over dry your scalp, and cause dandruff, even with the right oils
