I remember reading from doctor proctor that guys in some remote country who tranpsported ice blocks on their shoulders got hair growth on the shoulder they used to lift the blocks.
Therefore I thinking that the blocks caused some mild irritation (they wre probably heavy and scratching the skin even through the clothes)
So maybe we can try wounding and then for a week after or two apply some cold towls ( doesnt have to be freezing)
It seems normal to me that it would cause hair to grow as a natural defense to keep warm
What do u guys think ?
