hey Dylan, how long did you try finasteride for? and what dose? it didn't slow your hair loss at all?
if you were to describe your hairloss, would you say you have typical male pattern baldness or is it thinning all over? maybe showing us a picture of your hairline would help. i've heard sometimes people with diffuse thinning may have a micro nutrient deficiency or trouble absorbing nutrients.
you have to think long term with this - if you get a hair transplant now but your hair continues to fall out, it will eventually look much worse (very unnatural) than if you just shaved it. so priority #1 now is to stabilise the loss, then you can think about transplant if its required. i have seen cases of diffuse thinning return back thick. more so than normal pattern baldness where the hairline starts receeding.
