Introducing my spring/summer 2011 obsession: Feather hair extensions. I saw them somewhere online about 2 months ago. I was immediately intrigued and delighted to find out they were easy to install and rather cheap. After waiting for Philadelphia to get their act together (I think this trend began in LA – of course!) I finally got them this weekend and am beyond thrilled. I had mine done at Moko organic hair and beauty salon in Old City. Jessica was adorable and sweet, and she did an great job. The extensions last between 1-4 months depending on how harsh you are on them & Moko can also do adjustments to the extensions as your hair grows.
