I'm considering hair loss treatment. Is it really important to start early?

Lately, I've been really worried because it seems like the amount of hair falling out every time I wash it is definitely more than before. At first, I thought it was just because of the season, but since this situation has continued for several months, I'm starting to get worried for no reason.

When I look in the mirror, it doesn't seem very noticeable yet, but when I take photos or am under bright lighting, the crown of my head feels a bit thinner than before. My family members also comment that my hair looks like it has thinned out, so I think I'm becoming more sensitive about it.

So, I am looking into hair loss treatments, and after searching online, I found a lot of talk saying that the earlier you manage it, the better the results. On the other hand, there are also opinions suggesting that I should try taking medication first, so I am confused about which option is right.

Has anyone happened to start hair loss treatment in the early stages? I'm curious if the satisfaction level was high even when the condition wasn't severe yet. I'm also worried that waiting a little longer might mean it's too late.

I am also curious whether you took care of your scalp while receiving hair loss treatments, and if you significantly changed your lifestyle or dietary habits. I’d love to hear about your actual experiences, such as whether getting enough sleep helps or if you took any supplements.

I've seen a lot of promotional posts, but as expected, stories from people who have actually received the product are the most helpful!! Please feel free to share everything you were satisfied with or found lacking~~
