Kate Middleton's hair continues to look stronger and fuller ever time we see her. She stunned next to hubby Prince William at Wimbledon in London on July 2. Find out how to get her healthy hair below!
Kate's hair was down with tons of volume. It looks like she used a curling iron to give her hair some curls and bounce. It looked amazing at the tennis match. We're so jealous of her thick hair!
Her makeup was her usual style - a smokey eye and bright pink blush. Her fashion was also on point
, if you know what we mean! She re-wore a dress she previously donned while on her Royal Tour
of Australia in April.
To get shiny and soft hair like Kate, we love the very advanced Kerastase Chronologiste Deeply Nourishing Restorative Hair Treatment. The Kerastase Chronologiste Caviar Ritual is actually offered as a special summer service at The Red Door
, located in Union Square in New York City, and I got to try it in May. It left my hair silky smooth and frizz-free - so luxurious! Plus, who doesn't love to be engulfed in caviar?
If you haven't been to the new Red Door, book an appointment ASAP. They do hair, makeup, nails and they even have a full-service spa - it's beauty heaven! I especially love their "speed menu" for busy New Yorkers like myself.More From Hollywood Life:Kate Middleton's Perfect Eyeliner & Bouncy Hair - How ToKate Middleton Continues To Look Stunning Despite Hair MalfunctionKate Middleton's $10,000 Royal Tour Hair Secret RevealedClick through the gallery for more celebrity hair looks we love.
