Hello!
Does anyone have any experience making hair knots like these:

I tried different techniques, but non worked:
I tried this using a curve controller for hairs, I tried different settings, but none worked or looked nearly close to acceptable:

And grooming regular hairs into a knot is nearly impossible and the result isn’t very good also.


I just don’t have any idea how to do it. Please help!
