"Signature" advertising for a hairdresser

Unusual. An well-designed ad for a more or less local hairdresser/spa. Like a good slide:

• You get the point instantly
• Understated, elegant, and lots of white space

I like the small light-source-behind-the-model effect, I will experiment with it in my next presentation using a radial-gradient with very close color shadings.

Still, there is something "criminal" associated with a finger print (as people suggest in the comments of Ads of the World, where I found this image).
