Maintaining a Hair Patch in Japan — Anyone with experience? Struggling to find scalp protector

Hi everyone,

I’m moving to Japan soon and plan to maintain my hair patch (non-surgical hair system) using the taping method — no glue, just tapes like Walker or similar.

I’ve been trying to plan ahead and would love to connect with anyone here who has experience maintaining a patch while living in Japan, especially if:

You lead an active lifestyle (sports, workouts, etc.)

You’ve figured out routine maintenance, cleaning, and reapplication

You know good local or international sources for hair patch supplies

My biggest concern:

I’m struggling to find a proper scalp protector (like Walker Scalp Protector or similar).
It seems these products are either not listed, marked up heavily, or simply not available on Amazon Japan or Rakuten.
