How do you deal with anxiety about cutting dolls' hair?

This is so silly, but I'm so anxious about cutting my Pomni doll's hair into her iconic bob hairdo, I'm terrified I won't like how it looks, it will stick up in ways I don't like, etc.! 😩 I rooted her with nylon from Shimmerlocks.

I finally just now cut her bangs, and they look sooo good, until I comb her hair and it just pops right up!! Despite the repeated dips in hot water 🫪 I keep putting her in a plastic bag in hot water to tame and style it. Should I use some glue?

What do you do when cutting and styling doll hair?
