I'm getting a haircut soon, and I want to get it cut like Kristen Stewart's in the first picture, or a longer version of the girl with the headband's style. Basically I just want to know what I should ask the barber(or is it hairstylist?) for and how much work it would take (hairspray, ironing, ect.) to have my hair look like that. Also: Could this hairstyle potentially make me look like Ke$ha in the picture below? Because if so, I don't think I'd want to get it.

I want to dye my hair an unnatural color (like red or blue) but my face is reddish and I don't want to accentuate that, but I do want something that might bring our my eyes, which are green.

or color combination. I'd actually prefer unnatural colors, an i have green eyes and pinkish skin if it makes a difference.
