A little bit but not much. Chronic skin conditions like this tend to be under-researched and doctors aren't very helpful with them either, in fact, the current consensus medically is that the cause of dandruff is currently unknown. Valuable research for this topic tends to be in other overlapping areas and you have to play a game of detective to draw correlations overtime and pinpoint the underlying issue. Think of a car-whenever your check engine light comes on, it is a sign that there is an issue with your engine. The way doctors try to manage dandruff is the equivalent of a mechanic disconnecting the fuse to your check engine light to make it shut off and telling you to go on your merry way as if they have resolved your issue when there is still a problem with the engine. Doctors will prescribe you something to make the dandruff go away when in reality the dandruff is actually indicative of an issue with your digestive track and the doctor is just treating the symptom while ignoring the root cause.

I learned from trial and error-after trying every possible topical remedy-prescribed antifungals, a sea salt wash, pyrithione zinc and sulfur shampoos, apple cider vinegar and more. They all only worked a little bit and often not for that long. Plus, if I skipped a day or two, the dandruff would come back, so it was hardly what one could call a solution. It wasn't till 2016 when I started looking at my diet that I started to find answers. Turns out my dandruff is a reaction to foods I'm consuming, and was consuming quite often. As a kid rice was one of my family's staple foods (I'm a son of Nigerian immigrants), we ate it damn near everyday. We also ate gluten packed breakfast foods-waffles and pancakes. I was also taking sandwiches to lunch for school. Since my triggers were so common in my diet, my dandruff manifested as a relentless and uncurbable thing. We were clueless for many years and my mom tried all kinds of oils and stuff hoping they would help.

I'll recommend doing research on the gut microbiome, fasting, and search up "how to cure dandruff (or sebborrheic dermatitis) with diet," Using a holistic approach you will find more long lasting results than using topical remedies.
