Hair Highlights

Jessica Simpson and Sienna Miller both look so fresh and ready for summer with their easy, breezy blond locks. Non-hair side note: How cute are those rompers?

Both Hilary Swank and Kate Hudson were snapped on the streets of New York this week. Perhaps they're smiling because they realize they have incredibly enviable heads of hair. Check out Kate and Goldie, plus more mother/daughter BFFS!

Two of today's most popular one-name-only songstresses — Ciara and Fergie — looked super chic this week with silky straight manes (and very rocker-friendly studded accessories.)

Kate Beckinsale and Kendra Wilkinson-Baskett are all tied up ... in buns. Kate's is sleek and polished, while Kendra's is loose and sporty — which suits them both perfectly.

Dark and wavy is very in right now for actresses Jessica Alba and Katherine Heigl. Jessica's hair is darker than it's been in a while, but it's Katherine's that is still taking some getting used to. We have to admit, we miss the blonde.

Could two people look more fabulously casual? We think not. Kate Bosworth and Jessica Biel look every bit the effortless New Yorkers with their long locks in middle parts. We wholeheartedly approve.
