Because everyone has a lazy day
There's always at least one point in your life/month/week (delete as appropriate t your level of laziness) when you just really can't be arsed to wash your hair. C'mon guys, we've all been there.
Here's an easy simple style that literally takes 2 minutes.
What you'll need:
No sense of shame in leaving the house without washing your hair
Dry shampoo the shit out of your hair
Deep side part and start braiding, along your hairline, grabbing extra sections of hair as you go.
Clippy clip clip
Braid the opposite side of your hair and clip
Grab any annoying straggly bits and 'fold' them under the braids, securing with a clip.
Relish in tricking everyone into thinking your a well-rounded adult who didn't wake up too late to wash your hair.
