Mehron Hair White Colorant with brush offers 30ml of premium white hair coloring, allowing you to easily achieve a desired look. Use the included brush for quick and simple application, then remove with shampoo when ready. Achieve a silver or white effect by brushing or sponging it into the hair. Hair White gradually darkens as it dries and additional coats may be necessary for a more natural look. For optimal results, apply coats in small sections to create a natural variation in hair color.
