Is voluminous hair care available?

Maybe it's because of my age, but my hair is getting thinner, and it feels like hair loss is slowly starting to progress.

My hair was originally thin and weak.

It's a total mess.

I want my hair to look like this, but I want to make it a little more voluminous.

If you have volume, your face looks better and your hair thickness increases.

I think it's good that there seems to be a lot.

I'm curious about hair care for volume, wondering if you have any tips or good products.
