What is the correct way to attach hair to a body and animate it?

[klyuchka_liza]

I found these videos on YouTube.

1.https://youtu.be/7IS_tnkO_oU?si=Ai0ruqo2DNu21jjU

Or the second video, after which apply dynamics simulation

2.https://youtu.be/Ahrc-ih5q_w?si=lNXHqgIrLdThqNOL

Or if both of these methods are not suitable, how to do it right?

(In my case, Xgen hair is not attached to the body, but to the scalp, which is attached to the body.)

I would be very grateful if you could help me.
Thank you.
