Is scalp massage effective for preventing hair loss?

Lately, my hair has been getting thinner and the amount of hair falling out is gradually increasing, which is concerning.

As the sunlight gets hotter, it seems like the scalp is getting more damaged, which makes me sad.

There are many scalp massage techniques for preventing hair loss, including hand massages and massages using dedicated brushes, I have heard a lot about them.

But if not done properly, it can also irritate the scalp and may not be effective, so I'm curious~~
