With the popularity of the rainbow hairstyle that caught on in a big way last year, it has now extended to other areas as well. The latest offshoot of this trend is the eyelash make-up trend.The trend went viral after a neon-eyelash look, created by make-up artist Karin Westerlund for model Ginta Lapina, was shared on social media. You can use coloured mascara, eyelash extensions or even create your own using coloured eyeshadow pigment and clear mascara.
