Julia Roberts showed off a tres fabulous lighter 'do at a tribute to Tom Hanks at the Lincoln Center. Roberts has experimented with just about every hair color under the sun, but this blonde look suits her well. It's always easier to go lighter for spring and summer since your hair gets naturally lightened by the sun, chlorine and ocean saltwater, and darker tresses usually end up going a shade or two lighter anyway.
If you are a dark haired person (like moi), I recommend Frederic Fekkai's SunshineShield spray ($22). It has special silicones to deliver shine plus UV protection and solarshield technology to preserve the color and moisture that the sun tries so hard to take away.
