Depending on how you dye it, it can make your hair look 'cool' . Other than that some people are genetically cursed and have hair color that doesn't fit them at all, hence hair dye.
Short, very fine, silky, and erratic. I always have my bangs slightly longer than the rest, creates a wave effect cause of some weird thing with my hairline. I forget what it's called.
When it's longer, it's wavy. My parents won't let me grow my hair out though, even though I don't like short hair. -.-
That why it was in qoutes because it's personal definition, I mean I just look at cool, as something I like. What I mean by hair color that fits you as in fit's your complexion, a friend of mine dyes her hair, because it's the same shade as her skin etc.
I like to have Short to a medium spike to my hair, i don't like it to be on end tho, so i try to make it have a bit more of an effect to it with how it falls from the outside in, for a time with a certain barber, it would form a small Mohawk, and was looking amazing.
It grows withing 2 weeks to about 6inchs and so i have to be sure to get to the barber on time before that happens.
Here is an example of it from a while ago:
It may be at night, but you can make up my Brown hair with the light brown outline almost =]
That t-shirt actually had buttons, but that was during august, the humidity was high and the temperature was around 28 Degrees. Roughly 80 Fahrenheit, so i tried to keep as cool as possible, this was also taken at around 10pm.
