• Rinse hair in warm water instead of hot water
• Focus shampooing on the scalp to mid-lengths
• Focus conditioning on tips to mid-lengths
• Use dry shampoo to freshen-up hair and minimise wash frequency
• Pat hair dry rather than rubbing
• Switch your regular towel for microfibre or even a T-shirt
• Avoid detangling wet hair as it's more vulnerable to stretching and breaking
• Detangle dry hair gently from the tips and work upwards – never tug on tangles
• Go for the lowest possible temperature when heat styling
• Air-dry hair instead of heat styling as often as possible
• If you're a ponytail girl choose silky scrunchies rather than elastic ties, and don't tie them too tightly
