community I asked Chat GPT to "deep research" Glycerin based Minoxidil vs PG, and this is the summary of it's results.
Glycerin-based minoxidil is as effective as PG-based minoxidil for hair regrowth but causes less scalp irritation and systemic side effects. Glycerin provides sustained absorption, making it a better long-term option for those who experience irritation from PG.
