Love it
Color: Purple, Color: Purple
My grand daughter wanted a purple Rumi look for her birthday party, the actual braid is synthetic hair, but the hair on her head is hers with this spray on it...she loved it and the color came out nicely on her dark blond colored hair!!! Now, the party was at a play place where she was active for a good 6 hours...it did fade a bit, especially in the front where she was sweating and the overall color was lighter by the end of the day, but it lasted through a great amount of activity and there was still purple in her hair at the end of the day!!! Pretty impressed by that!!! I didn't test it on dark hair, but I would think the purple would be darker on brown or black hair!!!
