As a general concept I agree with you absolutely. In my case, I lack the bone structure to support short hair and I've had pretty much the same long/curly/tinted look for the last 20 years and am pretty attached and allergic to change. I like to hide behind it. And when you treat it like that it doesn't seem to grow very quickly because you have to trim the ends all the time.

I was half blonde for a while there, in thick stripes.
