Question

The appearance of your hair can indicate many things about your attitude and your health.

Answer 1

True.
Your hairstyle reveals about your personality. Let's take a girl as a example. 
Imagine that you are attending an interview and you badly want to get selected. You are extremely smart, but your hair is flimsy and messy and strands of hair are standing out. You think that they look at your study qualification and thus you did not mind about your hair. So you let it the way it is. But in the end, you did not get selected because of your hair.

Regarding health, 
Let's say you have thyroid disease, it causes hair fall. This happens due to the lack of care for your hair. This is a mild issue. Even undergoing treatment will take several months for your hair to grow back but not completely. 

Hope this helps ^_^
