Often what people call “dandruff” is not actually dandruff. You might have dry scalp, which causes flakyness and the dandruff shampoos do nothing to help (I’d argue they even make the dryness worse!)
In my case it was dandruff and what made a huge difference is to wash twice in a row (lather, rinse, repeat). I leave the shampoo in my head for a bit on the second wash while I do my other shower business.
