Swedish Subway Ad Sends A 'Hair-Raising Message' That Shouldn't Be Ignored

Back in February, a clever Swedish subway shampoo ad, in which a woman's long hair blows around her face whenever a train arrives, went viral. Recently, subway commuters spotted a new ad that uses the same windblown concept, but adds a powerful twist.

This PSA captures the subway-riding viewers' reactions to the unexpected ending. We don't want to spoil anything or diminish the effect of the video, so please take a moment to watch for yourself.

The Swedish Childhood Cancer Foundation sponsored this ad to highlight some of the devastating effects of cancer on kids and implore individuals to donate to the organization.

The stunned reactions of the people in the video really say it all. When globally about 175,000 children are diagnosed with cancer each year, we are all onlookers to this "hair-raising message."
