Ariana Smith is only 3-years-old and she's already got a heart that's bigger than most of us. After she saw a little girl who was sick in a video who didn't have any hair, she told her parents that she wanted to give her some of her's.

Her parents decided to oblige, and donate her hair to Locks of Love, a nonprofit that provides hair to financially disadvantaged children suffering from medical hair loss.

The hairdresser chopped off 10 inches of Ariana’s hair.

She was also very pleased with her new hair-do.

Truly a heart of gold.
