Mount Kailash is a holy site to Hindus, Jains, and Buddhists. People climbing it would plainly cause lots of butthurt from the involved parties, and climbers who were offered permission to do so (including Reinhold Messner) did not take up the offer for the same reason.
As of today, China has also banned any mountaineering on Mount Kailash for the same reason.

Probably exaggerated. What I could imagine is that the the atmospheric conditions up there slightly cause your skin to retract/shrink, exposing more of the nail/hair in the process. A bit like with corpses whose nails and hair supposedly continued to "grow" well after death.
The more interesting part is that "Russian scientists" suggested the top part of Mount Kailash is actually man-made (and/or houses a nuclear reactor). Sadly, none of the sites I looked up ever bothered to explain just who these "Russian scientists" were.
