Sometimes it’s the simple things that really stick in your head. Like the Über-minimalist center parts at Calvin Klein, the perfect complement to Francisco Costa’s Über-minimalist collection.

See these spring 2011 hair ideas and more (messy mohawks at Elise Øverland, topknots at Diesel Black Gold, etc.) in the slideshow ahead.
