I L-O-V-E laying out in the sun. Unhealthy, I know. But you only live once :)
Only once in my entire life have I ever had my hair highlighted from a professional. Never used a box. Never went back to the hair salon. My hair has always stayed its natural color, with a little help from some lemon juice and the sunrays and chlorine in the summer.
I'm curious to see if there are any other ways to enhance natural highlights in hair over the summer. Here are a few ways I've heard you can do it:
Lemon Juice: Spray on to wet hair and brush through before going out into the sun.
There are also lots of John Frieda Beach Blonde products that are amazing...
An egg bath: Eggs help moisturize hair because they contain lecithin. Simply beat an egg, apply it to your hair when dry and then cover with a plastic bag. Allow the egg to sit for about 15 minutes before rinsing in cool water.
