POWERFUL AD: Cancer association reinvents creative subway poster

Earlier this year, a Swedish ad demonstrated how hair products would "make your hair come alive" with an inventive subway ad in which a woman's hair was blown around by the gust of a passing train.

It made commuters stop, but this new take called "A hair-raising message" made them stop and think.

The stunning twist highlights the struggles of those who are battling cancer. According to the National Cancer Institute in the United States, this year alone 15,780 Americans under the age of 20 will be diagnosed with cancer and 1,960 will die.

The powerful ad was put together by Barncaner Fonden, a childhood cancer association in Sweden. They used the same technique as the original ad to create their poster.
