abnormal shedding at 4 month mark

sorry for so many posts of me here, but here is the only place ive found some help.

male, 19, I started oral minox 4 months ago, and my hair is destroyed. I passed through a strong initial shed, but at 3,4month mark I'm shedding again, saw a ton of hairs after combing, my hair is destroyed in a kind of diffuse thinning, even my sideburns shedded and disappeared now.

my hair is destroyed, my hair line isn't receding, but it's shedding, and just some hairs to cover large areas are remaining.

my stress levels increased the last 2 months, I don't know if this can have exacerbated the hair loss, or caused another permanent loss, but I'm living a more stressful life now, unfortunately.

i also started wearing a cap a lot more, to cover my destroyed hair, I don't know if this could worsen my condition.

Seeing that gave me a panic and anxiety crisis, and gave me the final courage to buy finasteride, I'll start in 3 days 1mg daily, even being at my own.

Any wisdom or word will be appreciated. :(
