Sandra Bullock's Shiny Hair Secret

The ever-ageless Sandra Bullock stepped out at The Change-Up premiere in Los Angeles on August 1 with a few tricks up her sleeve. Not only did the 47-year-old actress surprise her co-star from The Proposal Ryan Reynolds (who also stars in The Change-Up) on the red carpet, but her hair looked exceptionally shiny and healthy.

The star's hair pro for the night, Couture Colour celebrity hairstylist David Babaii, let Us Weekly in on the secret behind her gleaming tresses.

Before whipping out his styling tools to give her a red carpet-worthy 'do, Babaii treated the actress' strands with Couture Colour Pequi Oil Treatment ($32, couturecolor.com).

The formula, which is derived from the Pequi fruit, is packed with hair-replenishing antioxidants, tames frizz, and helps keep color vibrant. And in addition to being used as a treatment, the oil can also be used during or after styling as a serum.

The best part is that it works on every hair type without weighing down your tresses -- great for whether you have a super-thick mane like Rihanna, finer locks like Kate Bosworth, or strands just like Bullock.[usmagazine.com]
