Fabby Hair is a fun app that lets you colour your hair and try a new hairstyle virtually. Those people who are contemplating colouring their hair but are not sure how the new hue would look like can try this app and get a fair idea of what to expect. You can even snap pictures and capture videos with the fun colour overlay. And these could be shared online on Facebook, Instagram, Snapchat, etc. There are different colour choices available, including purple, blue, platinum, pink, and magenta, to name a few.
