Don't worry, guys. Grey hair isn't the end of the world and you won't look hideous when it happens. : )

My older sister is 58 and doesn't have one grey hair. I started going grey in my late 40's and am now 60-70% grey I guess (I don't color it), my younger sister started going grey in her teens and is probably 80+% grey (tho it's hard to say since she has been coloring it all these years).
You just never know when it's gonna happen.
--I'm located in Western PA.
--I found NC in late 2004, CG since 2-2005, started going grey in late 2005.
--My hair is 3B with some 3A, texture-medium/fine, porosity-normal except for the ends which are porous, elasticity-normal.
--My long time favorite products are Suave & VO5 conditioners, LA Looks Sport Gel, oils, honey, vinegar.
--My CG and grey hair progress --
