Lithium grease does harden overtime, especially white lithium grease. as a result of oxidation, base oil evaporation and the fluctuation of temperatures.
The extent of the hardening of the lithium grease can also vary depending on the specific grease formulation and usage conditions.
White lithium grease does get hard overtime and dry out, especially when the white lithium grease is exposed to air and heat.
When the white lithium grease gets hard it can actually get as hard as cement and cause issues such as jamming of things and seizing of the things that it's supposed to be lubricating.
White lithium grease was used in the 50s and 60s for lubrication of seat rails by automakers but over time it can dry out and harden and jam the seat rails and other mechanisms.

And white lithium grease may also have added ingredients like PTFE or Zinc oxide for water resistance and other certain purposes.
White lithium grease is often used in applications that require resistance to water, protection against corrosion and in places where a cleaner and more visible grease is needed.
Examples of some white lithium grease are CRC White lithium grease and WD-40 Specialist White Lithium Grease.
white lithium grease is also commonly used for sunroof panels, door hinges and other applications in which water and corrosion are a concern.
Regular lithium grease can be various colors including red and brown depending on the additives.
