Okay, Brit - I'm gonna ignore the lack of a bra in the company of your parents. But you know your hair is bad, when your non-famous mother is rocking cleaner, nicer hair than you are. I actually really like Momma Spears hair in this shot - it has fun texture and is appropriate for her age.
There are few steps you can take to improve that hideous hairstyle you have on your head.
1) Wash it.
2) Stop using so much product - it just leaves your hair looking Crispy. Short hair is easily overwhelmed by product, and you must use sparingly.
3) Either be more on top of your roots, or add in some lowlights that are closer to your natural haircolor. Far too many women go for an all over light color - when they can just get a good percentage of their hair highlighted. It grows out more naturally, you'll save money on touch ups, and it will look so much more multi-dimensional and healthy!
