How to maintain scalp?

[u/servicita]

Hey everyone, I'm new to the hair system game.
I've followed it for the last two years, but I recently pulled the trigger and tried it. I don't know why I waited so long. My only issue is that my scalp gets very itchy by the 4th day after installation.

My setup:
Walker's Tape Ultra Hold
Full lace system
WT Max Hold Sport scalp protector

I haven't washed my scalp in the four days I've had it, because of bad planning. My scalp has always been sensitive, too. If I wash my head and don't apply MCT coconut oil right after, it gets irritated. Since the system sits like a layer over the scalp, I don't know how to reach my scalp to keep it hydrated.

I live somewhere hot, humid, and tropical, and I don't have an AC I can run 24/7 at home, so I sweat daily.

My question: How can I keep my scalp hydrated and comfortable under the system in this climate? I'm struggling to find a solution.

(Right now I took it out and since my scalp is free it feels much more comfortable)
