The disaster: A crease in your hair
What to do: This requires a little work, but is fixable. If you do have heat styling tools with you (like a blow dryer or flat or curling iron) then you’re golden. You can use a flat iron on the creased part (for straight hair) or a curling iron (for wavy or curly hair). Or, you can wet the creased area while brushing through your hair until it disappears, then blow dry the wet section, says Los Angeles based hairstylist Anthony Cristiano.
Stuck without your styling tools? Wet your hair like Cristiano said, run your fingers through to lessen the crease, then use the hand dryer in the bathroom to dry your hair. It’s not perfect, but it’ll work.
