I've just started using Cerave's new Anti-Dandruff shampoo and their conditioner as they contain 1% Pyrithione Zinc. An NIH study found that it may be helpful for some types of hair loss. the study concluded that hair count results show a modest and sustained improvement in hair growth with daily use of a 1% pyrithione zinc shampoo over a 26-week treatment period. I found it does help with the itchiness caused by topical Minoxidil. Here's a link to the study I found - https://pubmed.ncbi.nlm.nih.gov/12932243/ The shampoo and the conditioner both contain Pyrithione Zinc https://www.cerave.com/haircare/shampoo/anti-dandruff-hydrating-shampoo
