Hair highlights are very popular nowadays, and hair extensions are becoming increasingly popular. You could merge both hair trends by wearing high-contrast hair extensions to prom.
Brooke Hogan's hair is in a beautiful blonde color and she is wearing two-tone extensions with highlights and lowlights. The hair style itself looks like a modern version of the old famous Farrah Fawcett hairstyle. It has many layers for gorgeous feathering—and it's quite big—but the volume is much less than Farrah's classic hairdo.
Besides extensions, the key to this evening hair look is getting enough lift at the roots along the hairline. Brooke achieved this sexy look with an amazing blowout. The right hairdrying heat will get both the nice lift at the top and pretty feathered style in the middle.
With her hot hairdo, the beautiful blonde girl is wearing a sexy halter evening gown. The gorgeous hip-hugging shimmery purple fabric makes the most of her curves. If it was a little higher, though, it would be perfect.
