You can of course opt for an OTC medicated shampoo (which tends to have lab-derived ingredients), but there are some pretty potent natural-leaning numbers that also do the trick. Allow us to introduce you to the treasure trove of natural dandruff shampoos: These incorporate plant-based actives known for fighting off flakes, and they sure do put in the work. Perhaps this goes without saying, but these shampoos are pretty potent, so you don’t want to use most of them every single day. Even without traditionally stripping ingredients, like sulfates, these lathers can dry out the skin when used with every rinse. Lay off once the dandruff subsides, or continue to use with your weekly (or biweekly) clarifying cadence.
