Yeah , on top of how ad-infested and vague the article is and on top of the discussion I’ve seen about this paper elsewhere, it looks like at least one of the authors, Adrian David Cheok, doesn’t have any physics training according to his ORCID bio or his his wikipedia page, but has dabbled in AI according to the latter.
I wouldn’t be surprised if this is just some AI schlock.
I second the request for a citation.
Feel free to refute this, but here’s an article I found that suggests there’s little evidence that Head and Shoulders is bad for your hair - at least the ones that aren’t Clinical Strength.
Minor anecdote: I used to have severe dandruff, then I started using Aveeno’s Apple Cider Vinegar products and that helped a LOT, but now I use the ACV H&S and I haven’t had any real complaints since the switch.
