Approximately how much does a hair loss clinic cost?

My dad said he wants to go to the hospital for hair loss and asked me to look into it for him.

I’m thinking of taking him there first, and if he says it’s okay, I’d like to get him treatment right away.

Could you give me a rough idea of the treatment costs at hair loss clinics in Seoul?

It looks a bit like alopecia areata to me! ㅠㅠㅠ Please recommend a good clinic if you know of any.
