Looking for advice on getting loose fitting after a tummy tuck procedure

Hello, friends! I am planning to have a facial in Seoul soon and then I have to go back in about a day. I need some good information on how to take care of my loose hair. I think there are people here who have had various types of facials, so please give me some good advice.

I would like to understand in general what kind of products I should bring. Should I bring extra moisturizing gel, or a toner, or something like that? Also, how many hours do you think I should keep my loose hair properly when traveling by train?

If you have any experience or good information, please share! Thank you very much.☺️
