At what stage of hair loss is treatment recommended? Can I get a consultation even if it isn't severe yet?

The part I'm most unsure about right now is whether I really need hair loss treatment.

It’s not like people around me say my hair looks thin, but if I compare it to my old photos, the feeling has definitely changed a bit.

It feels like my hair itself has gotten thinner than before, and after drying it, it doesn't seem to have much volume overall.

However, when I actually searched for hair loss treatments, I saw a lot of reviews from people whose condition was quite advanced, so I wondered if it was too early for me to start now.

Does hair loss treatment necessarily apply only to people whose hair has thinned noticeably?

Or I am curious if there are many cases where people seek consultation even at the stage where they feel their hair loss has increased or their hair has thinned.

I don't want to wait a few more years and then regret not taking care of it later.

That said, I don't want to blindly start hair loss treatment that isn't even necessary in my current condition.

I am also wondering if, during the initial consultation, I can receive an explanation after they assess my current condition whether treatment is truly necessary or if trying lifestyle changes or home care first would be sufficient.

I am also curious if things like family history are considered important when determining who should be recommended for hair loss treatment.

Even when I've been stressed or sleep-deprived in the past few months, it's difficult for me to tell on my own whether the lack of sleep is temporary or if there is another cause.

Has anyone else, like me, started by getting a consultation for hair loss treatment at a point where it was hard to say for sure if it was severe?

I wonder if you felt relieved knowing that you didn't go too early and were able to check the condition.

I would also like to hear from those who have actually started hair loss treatment what changes they saw that made them decide to start managing their hair loss.

I'm especially curious about the experiences of those who started early on, haha.
