I noticed that I always get instant dandruff when I use Vaseline shampoo. The dandruff that I get are those large and flaky ones, and take note, I thoroughly rinse my hair. It happens only when I use Vaseline shampoo, so I think there's something in it's ingredient that triggers dandruff, because I asked many people if they also experience that when using Vaseline shampoo and they said that they do, and they get dandruff all of a sudden. So I wonder if any of you had the same experience where you get instant dandruff just by using a certain brand of shampoo?
