"When all else fails, buy some cute accessories such as barrettes or headbands to tie back your hair and avoid humidity wrecking your curls," said Casamassima. "Tie up your curls in a loose bun." She suggests using Invisibobbles Hair Ties (£4) to avoid creating dents in the hairstyle.
"If your curly bob is too short to tie up, you can also incorporate silk scarves or bandanas," she suggested. "When the humidity and heat rise and your curls start to grow, you can manage them easily and still look cute." She loves a hair scarf for this look, and uses the Nexxus Volumizing Mousse (£21) (she's a spokesperson for the brand) to keep humidity out and curls intact without stickiness or drying to a rock-hard finish.
