This 'Hair-Raising Message' from The Swedish Childhood Cancer Foundation takes inspiration from a shampoo subway advertisement that went absolutely viral earlier this year.
The original shampoo ad was displayed right beside the subway tracks, so that when the train pulled up to the station, the woman's hair would begin to blow in response. This ad from The Swedish Childhood Cancer Foundation plays off of this idea, but features a message that's related to raising awareness for cancer. Just like the shampoo ad, the same thing happens to the girl in the ad, but after her hair whips around for a while, her wig flies off, sharing the message that daily, a child is diagnosed with cancer. Since the first half of the ad is entertaining enough to hold people's attention, this somber part of the message is unmissable.
