The bob has been a big look for the past couple of seasons and Charlize Theron hairstyle is a longer version that is most commercial. it's the safer length of this style that most women feel comfortable with.
Ask for a classic bob that's slightly layered at the sides to give a softer look. The for colour, you need to ask for a combination of soft blonde, mahogany and mocha shades.
Charlize Theron hairstyle is a very high-maintenance style that will need to be cut every 6-8 weeks. It will need a good blow-dry with lots of shine spray spritzed over the style to keep that "just stepped out of the salon" look.
