Hair climbing shaft

But the presence of hair that was not there previously, indicates that stretching the shaft skin isn’t what is happening

I think Thunder is trying to say, is that if you stretch your skin (push it back to the base) it compensates the extra penis length gained by PE.

I am uncut and since I started jelqing I have noticed hair growing up my shaft by about one inch and I have not even seen any erect length gains yet (although my flaccid hang is considerably better).
