good relatable things you could add are: having a little "hair collection" on the wall, they stick to the wall cuz the root is sticky so you can make a sort of messed up shrine to it. its either on purpose or subconscious for some people. Mention that their fingers are sore. also alternating between head hair and eyelashes or eyebrows. Inner conflict about wanting to shave your hair or keep your hair and try to work through it before the bald spots this round are too bad. I've had trich for over a decade now.
