Hi :) Normally when I eat too much sweets/sugar I always remark that I will get 1 or 2 pimples on my head maybe the next day itself or some hours later and goes away or dry quickly by the next day. Today I just woke up and found blood on my pillow. Not too much but it is visible. I even saw the pimple on my head. So I am assuming that maybe when I was sleeping, I broke the pimple due to rough movement. What I want to know does it cause permanent hair loss. Does it have anything to do about hair loss?
