Not surprised by the legendary Debbie Harry chopped lob making a comeback. Last year we were all in a mermaid/long hair daze but for 2015 we are ready for the chop.
We've seen a few complaints from stylists thinking this cut won't last the test of time and outgrow into a shapeless one length, the trick is to add some interior layers and texture so that just the crown is kept at one length for those lines to show; or maybe even a soft undercut to keep the back from mulleting out. For those thick haired gals an undercut keeps it from being too heavy in the back.
Ask your stylist to wisp out the ends for a more disheveled rocker look.
The less work you put into this look the better it turns out, you may even get away with that extra day of dirty hair and that's why we love it.
