Warning : Welcome to this otherwise useless post.(I think and you will agree)  
Spoiler Alert : This is about the one white hair that hides all the black hair. Random bantering.  So apologies!
The hair doesn’t fall off on its own which makes me wonder – is white hair stronger than the black ones? I have combed, I have shampooed and lost few black hair in the battle but this white one seems to be going strong. Food for thought? Hope the black ones win in the long-term. 😉  Also next time you see my white hair, act cool.
