I would like to know the cost of hair loss treatment.

I am an office worker in my 30s who is just beginning to consider hair loss management. It’s not at the point where I need a hair transplant, but I’ve been worried about my receding hairline for a while, and I feel like I’ll regret it later if I don’t start managing it now! I’ve read reviews saying there is a huge difference in the long run between those who started early and those who began late. I feel like managing it at home with just cosmetics won't be enough, so I’m thinking of expanding my horizons to hair loss treatments. However, my biggest concern is, as always, the cost. It seems like hair loss treatments aren't exactly cheap. Spending a huge amount of money is a bit of a burden, so I’d like to gather some information beforehand. Which hair loss treatments have the highest satisfaction rates? I’m curious about the typical cost per session and how much cheaper it is if I pay for a package. Also, I see a lot of people taking hair loss medication these days; how effective are these drugs?
