It seems the coloured hair trend is firmly here to stay after Kylie Jenner rocked this stunning blue hair look while attending a Bellami Beauty Bar event. The 17-year old is no newbie to the coloured hair trend. Check out her bright tresses in 2014. But when we compare this to her new look you can see the updated style is a more desirable light pastel hue. Her newest colour looks feminine, bright and stands out perfectly against her outfit.
