A novel hydraulic damper, and a piston head assembly therefore, includes a feature, such as a slot or passage, which permits compressible gases that would otherwise be trapped between the face of a piston head assembly and the hydraulic fluid to instead migrate to a volume within the damper where they will not affect the dampening force produced by the damper. In the illustrated embodiments, the feature can be formed, relatively inexpensively, in the piston head assembly without the remainder of the damper components requiring modification.
