So I was at a friends house this weekend and he pointed me to this website…seems he has trouble growing hair on his shins. 
This apparently is due to guys suit pants. Having bought my first real suit recently, I noticed it was lined with silk (i think) about halfway down the pant leg. When I brought this up at dinner my wife asked why it wasn’t lined the whole way down. Anyone have any idea why?
WAG would be that the upper part of the pant leg is in more constant contact with the leg than the lower half so for reasons of comfort and wear prevention the upper leg is lined and the lower isn’t.
Good question, Pascoe.
Fully lined pants are heavier and only necessary for winter suits. Lined-to-the-knee pants generally offer year-round wearability and are lighter and more comfortable to wear.
I don’t think the hair thing is due to the pants. Dry skin in the winter can cause itching (and thus scratching and rubbing even during sleep) of the lower legs, to where the affacted person wears the hair off the shins and sometimes even wears through the skin enough to cause bleeding. I’ve seen it happen to a couple of people I know. I don’t know why, but is seems the hair won’t come back for years.
FWIW, I wear suit pants all the time and it seeems to have had no effect on my leg hair.
I wear a suit everyday of the work week and it isn’t the pants that’s wearing the hair off his legs. It is probably his socks.
The previous thread I spoke of actually determined that the cause of the shin baldness is wool suit pants. These pants are lined right down to below the knee. Below that is where he doesn’t have hair. The question was why aren’t they lined lower, but I think I have a good answer.
I agree with plnnr, it is probably his socks. My father has the same thing and we know it is because he wears these really tight socks, since he has lost the hair exactly to the point where the socks normally end. It doesn’t have anything to do with the pants.
It can’t be socks. He tried that variable using short socks, long socks and even no socks for a while.
