The thought that a haircut or color is like picking up a loaf of bread on your way home is still a reality in some parts of the world, yes it’s sad but some people have not experienced hair they love.
I guess for these people they can’t understand it simply because they have not experienced it. Hair is a complex medium that requires understanding of movement and reactions, it’s learnt over years not weeks or months.
We all know someone who has had a hair disaster and simply won’t leave the house, this is typical side effect of someone who shops on price alone and doesn’t really care about the end result. Well not until the end result looks more like a wig in a horror movie anyway.
