(Concern) Hair loss progressing. What should I do?

This is a type of hair that has a genetic potential for hair loss.

I used to have a lot of hair, but it seems to be falling out a lot these days. My hair is also getting thinner.

I'm trying out hair loss shampoo as well, but I still don't notice much of a difference. I've also been massaging my scalp at night, and I'm wondering if I should buy supplements or not.

Then let's not waste money unnecessarily and just go to the hospital first. I heard that taking medicine or getting injections is the most reliable solution, but when it comes to my own situation, it's really hard to make a decision.
