Make particle hair affected by gravity? Using Blender 2.81, is there a way to make dynamic particle hair fall and hang like in real life, affected by gravity?

I have made a scalp with hair and combed it how I want it. If I then enable Hair Dynamics and rotate the scalp 40 degrees, the hair will also rotate 40 degrees and stay that way (after jiggling a bit, back to it's combed state). But in reality, the hair should keep hanging straight down due to gravity even when the scalp is rotated.

Is there a way to achieve this effect?
Physic simulations in Blender don't update at any time (and that's a good thing, so you don't melt down your computer and you keep a responsive software as long as you need).

In order to the gravity affect your hairs, you have to start the playback. You have the playback controls buttons on the bottom left of your screenshot.
