If I have hair loss, would washing my hair frequently be a burden?

I'm worried because it looks like a lot of hair falls out when I wash it.

So I'm thinking I might need to reduce the frequency of shampooing.

However, my scalp tends to get oily quickly, so I'm worried.

I'm also curious if washing your hair frequently is directly related to hair loss.

For those of you who have tried scalp care, how do you manage it?
