It sounds like you’re way better off than me. I’m 31 and I’m pretty much a diffuse NW5 right now, and exactly 1 year ago I was pretty much a NW2 with some diffuse. I had massive hair loss over the course of one year. The amount of hairs I was losing every day when I had my hair super long were in the several hundreds. If you’re only losing a hair or two when you run your hands, or only 10 or so hairs in the shower, you should be okay. You can try to look into a LLLT helmet, I bought one back in November and have been using it pretty much all the time. Not sure how much it’s really helping my case because I’m in shit at this point, but for your situation it may be perfect.
