I can confirm that Bake All Dynamics button does not work with Hair particles.

It works for emitter particles or other physics simulations.

When you press this button with a scene containing a mix of cloth or soft body and Hair.
At the end of baking process, Hair particle system cache is calculated but not protected. Any object refresh can erase this cache.

If problem can not be solved easily ; at least, user should be warned.
