I have made a prototype for a new grooming tool in blender. It's been on my mind for a couple of years now and I haven't seen it in any other grooming software so far.

The idea is that you draw strokes in hair sculpt mode. The drawn stroke is projected from the camera and the existing hair curves align to your stroke.

Settings

The tool would have the following settings:

Proximity

Hairs which roots are within the proximity of the strokes root will be affected

Taper

How much the stroke tapers the affected hairs. How thin the tip would be compared to the root

Lift

How much the stroke will be deformed along the normal of the colliding geometry

Note on "gravity"

In order to "simulate" gravity, a curve point with higher index can't be farther from the camera than the previous point index.

Attached is a video where I showcase the prototype. Jump to 01:17 to see me start using the prototype.

I have also attached the .blend file

I am not a developer. Thank you for the introduction of new groom tool! It looks intuitive to use to make basic hair style.

However, I doubt that this tool is enough to make more advanced hair style, such as the following image:

Hair bun

To make the top hair bun shown on the image above,

1, the "gravity" probably have to be turned off, so that the hair can go up.

2, the hair bun is 3D, but this tool uses camera projection, which is 2D, which may be difficult to create complicated 3D hair shape.

3, at the bottom of the hair bun, the tool must provide a function to constrain the space of hair, so that the bun can be formed.

But, if your tool can easily do all of these, then that would be a bless to all character creators! Thank you again!

@Stay_Here Without VR and 2 hand controllers, you won't achieve this :), so don't try to set something like that as a goal. Everything is much simpler here i think.
