If you start with a topical product like minoxidil it can slow and even stop the hair loss process. Most supplements that claim to work as well are mostly bullshit. I’d also just embrace the gray. Most women won’t mind and a lot of people go gray early. https://www.menshealth.com/grooming/g39797585/best-mens-hair-loss-treatments/
If it continues to thin, just start cutting it shorter and embrace the bald look. Ultimately you need to decide what your comfortable with, but I can’t do the comb-over look.
I used to get upset watching and I realized it was ruining the fun. I took a step back and adjusted my thinking. My team losing is still frustrating, but I don’t yell at the TV or let it ruin my day.
