Sudden Hair-loss in 20s Male, What to do?

Hey everyone,

So, I'm in my twenties and just moved from Saitama to Setagaya for my first job after college. But here's the thing – in the last 2-3 months, my hair has started to get really weak and I'm actually losing it. This is totally new for me because my hair used to be super strong and, to add, there's no history of baldness or hair loss in my family.

I went to see a dermatologist and got diagnosed with seborrheic dermatitis. I've been treating it for a month and my hair feels a bit better, but the hair loss hasn't stopped. I'm starting to think it's not just the dermatitis. Maybe it's the new environment or something else?

Does anyone have any tips or advice on how to deal with this? Maybe some lifestyle adjustments or remedies that worked for you? Could really use some help here.

Thanks a bunch!
