The Blender 2.79 manual says you can edit a baked simulation (https://docs.blender.org/manual/en/dev/physics/particles/mode.html#bake-the-simulation).
Does this not apply to a hair simulation?
If it did, while being somewhat of a manual process, it would give massive control over hair and the ability to reshape and correct errors based on the guide hairs during the animation.
Exact steps for others to reproduce the error
- Apply a particle system to a basic cube, change type to hair and set emission low, say 50
- Turn on Hair Dynamics
- Under Cache, Bake the simulation
- Switch to Particle Edit mode, all the hairs will freak out and stay static while moving through the frames
