Do I need to be careful when washing my hair after getting Botox?

I'm looking into getting Botox for the first time.
I became curious about how much of my daily life I can go about as usual after the procedure.

Even if washing your face or applying makeup is fine,
I wasn't sure if it was okay to bend my head down or use hot water while washing my hair 🤔

I have an appointment on the day of the procedure.
I would appreciate it if you could let me know if there is anything you were particularly careful about in your daily life 😊
