Thank you for posting this question, and a thanks to @FutureMemory for the old link. It explains the sightings of a few young ladies in the neighborhood with this hair style.
As someone who participated in numerous trendy hair styles (long hippie hair in the 60s, Farrah Faucett fringe in the 70s, Princess Di look in the 80s), I get it. And there are more variation opportunities offered with Scene Hair than we had in the above mentioned ones.
The latest teen styles may change by appearance, but the intent hasn’t. It is a way to display the flexing of independence in choosing a look that isn’t dictated by a parent. It is a natural process of going from childhood to adulthood. The teen years are generally about learning to go against the norm of the previous generation while still succumbing to peer pressure.
So, do I think it is stylish? Yes, as a current trend. Is it stupid? Let’s just say that I don’t think I’d ever commit to the time involved in creating it. IMO, there are more stupid things to do based upon trends and peer pressures. A hairstyle is easy to change. Others aren’t so easy.
