Country superstar Carrie Underwood co-hosted the 2010 CMA Awards last night, and as usual, she looked stunning.

While the "American Idol" winner donned seven different fashion ensembles throughout the evening, it was her hair that really struck a chord with us.

Worn long and wavy for most of the night, Underwood's signature blonde locks had the perfect mix of a flawless style combined with an easy flow -- perfect for this country girl's charm.

To get her on-stage hair looking so healthy, Underwood reportedly uses RUSK's Sensories Wellness haircare products, including their Restorative Heal Treatment -- a deep conditioner with argan, coconut and olive oils that restores and strengthens color-treated hair.

RUSK Creative Stylist Sherri Jesse suggests applying the rich, creamy conditioner to clean, damp hair and combing through with a wide toothed comb to evenly distribute. Then pop on a plastic cap and allow the nourishing ingredients to penetrate into the hair shaft for 15 minutes. Rinse completely and voila! You've got softer, shinier hair that is red-carpet ready.
