I am currently using that in my hair, and I have dark brown hair. It gives it an aqua tint, depending on the light. Not really obvious, but noticable. I honestly love it. It looks really bright in the sunlight. <3
The Splat Aqua Rush hair dye will give your brown-colored hair a light aqua tint that can last for a few weeks depending on how many times you shampoo your hair. It has a creamy and thick texture so you have to shake the bottle before using it.
