There's nothing hotter right now than waves, & Jessica Simpson's hair in this picture from the 'Dukes of Hazzard' is pretty easy to get -- provided you have long, long hair. (Keep in mind that Simpson's hair here, is not real, these are extensions).
Here's how to mimic this look:
Apply volumizing tonic to roots. I like Bumble & Bumble
or you can try Aveda volumizing tonic
Blow dry hair until it's slightly damp. Blowdrying tip: Hold dryer above your head & train air downward so it flows from roots to ends. This way hair won't look dull & will be easier to manage.
Scrunch hair with fingers.
Spray in saltwater spray. I like John Frieda Beach Blonde Ocean Waves Sea spray
Let hair air dry (keep scrunching until it's totally dry)
Voila! Now you have Jessica Simpson's 'By the Sea' look!
