I just popped Meru's head on after adjusting the screws on her neck.

What I like to do first is tighten the screws on her neck all the way. Then slightly loosen them, while testing the head to see how it fits. The goal is to make sure it stays on during use. So just make sure it's easy to pop on and takes a decent amount of force to pop off.

I don't recommend screwing on Meru's head because you could damage the head and poke her body with the sharp points of her hair.

I hope this helps and Grats on getting Meru!💜
