"Step into the spotlight, it's time to shine! Pantene Pro-V's Ice Shine range gives you head-turning glossiness to deliver a healthier, more sophisticated look. It's superb moisturising and cuticle-smoothing actions provide hair with a dream ice-gleam that radiates from within, giving shine real depth. There is no doubt about it. Whatever your cut or colour - when your hair looks gleaming, you feel great."

I saw the commercial and thought to myself if that would really be possible. How could the hair be soo shiny?! I am not a girl but it has always made me thought if it could do what it says it could do. I would even try it for the sake of the answer.
