Yeah, it’s definitely YMMV. Also I read that minoxidil is only good for hair loss in the back, not for receding hairline. I was using it for almost a decade before I switched to a buzz cut, then shaved it all off. Unfortunately my hair loss was primarily in the front, so I’m not sure minoxidil ever did much.

(Fellow trans person btw, though I haven’t tried to use it before testosterone started kicking my hairline the way my genetics were pointing 😅️)
