Because it happens to the best of us.
Here are my easy problem solving hairstyles:
If the ends are the issue....
A Sleek Chignon
A Tight Braid(s) or Messy Side Braid
If your roots are the problem...
Half-up Half-down Bun
Put on a Beanie or Hat
Wrap a Scarf on your head
If everything sucks...
Messy Top Knot
Stay Fab,
Style & Repeat
