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.
