There's apossibility. But when I rinse after the BS part of the wash, I rinse for a minute or 2 and wring out my hair during and after. Then the ACV will get absorbed. Then I rinse and wring out my hair before doing a cold water rinse.
If there is a small amount of BS that gets mixed with the ACV, it won't hurt your. you start out with 1/2 cup of it. Once you rinse it out, if any is left, it's probably in the 1/8 of a tbls range. And that little, spread out all over all of your hair, won't create much of a chemical reaction
