Ask Questions about this Product

Would this be suitable to use with DIA RICHESSE 9.01 MILKSH GLA after highlighting with Blond Studio Multi Tech. I want maximum grey coverage but nice bright highlights. Natural hair color is dark brown.

Hi there! Thank you for your interest in our DIActivateur Developer 15-Volume. You should be able to use this product but we recommend performing a strand test as a preview to see if the color result is what you’re looking for! We hope you found this helpful.
