Kate Middleton Spends 4 Hours at Salon For Friend’s Wedding Preparation (PHOTOS)

Kate Middleton, Duchess of Cambridge, attended her friend’s wedding during the weekend. And she prepared for that by spending 4 hours in her favorite hair salon on Friday afternoon.

The salon is called Richard Ward Hair and Metrospa, which located in London's Chelsea area.

The service included coloring Kate's hair with organic vegetable-based hair dye, trims and treatments.

Not surprisingly, the 29-year-old future Queen of England looked outstanding with her glossy outfit.

Kate usually spends time and socializes with people in the salon for eight years. And, even after she became a royal princess, she still continues to come to the salon every eight weeks.

An insider told US Magazine, “She loves her time there and she has known everyone there for years so it's really relaxing for her.

Her family, including her mother Carol Middleton and Kate's little sister Pippa Middleton, have been trusting the hair salon for several years.
