why does the hair in the cast grow longer than usual?

I removed the cast from my left hand last week, and noticed that my hair had grown longer on that hand, compared to the healthy one Surprising, isn’t it? So I looked it up, and the answer is quite simple: the hair doesn’t grow longer, but rather it gets protected by the cast. Implicitly, it doesn’t get worn off as it does on the other hand. Simple and very interesting.

Just thought I’d share.
