I have natural light brown hair with bleach blonde highlights. I need to have black hair for my Halloween costumes. I don’t want my hair to be in all types of colors when I wash the hair spray off. Does anyone know if it is safe to use the black hair spray on bleached hair? Or should I just get a wig or something? Can someone tell me about this appropriately? I would really appreciate an early response from you guys who have done it in the past. Thanks.
