Restricting Hair Strands: Tips and Roots

It’s as the title says. I’ve got an alembic hair asset in several parts. One of these assets is a group of strands that feed into a secondary, separate asset, in this case a hair bun (the bun and hair strands coming out of the scalp are separate assets). As such, I need both the roots and tips for this particular asset group to be held in place.

Now I can obviously just disable the wind factor on the offending group, but I would optimally like for that group to wave around, with both ends anchored into the hair bun and scalp, respectfully.

What’s the correct or best way to solve this?
