I think people spend too much time on their hair. 

Too much time wasted about hair....something for which very few others care!

It grows and it grays it rusts and it falls. 

Time in the morning which could be better spent considering nothing or doting on the profundities of a sunrise are spent combing, crimping, straightening and productifiying. 

Too much time spent on this way or that-spiky or flat. Assuming the person you want to notice will care.

Truth be told the only thing on their mind? Is there hair!
