I try to dye my hair at least every 3 weeks to keep the gray roots at bay. The box dyes have you mix the bottle and then apply directly to your hair but it is not the easiest thing to do and I often end up with dye drips on my floor, my clothes and my sink. Saw this online and decided to try it out. This kit makes things so much easier. Instead of mixing with the bottle, I now put it all in the bowl and mix it with the brush. Makes for a more even mix than shaking a bottle. Application of the dye on my roots is much easier with the brush and applies more evenly and thoroughly than with the bottle. This has made dyeing my hair much easier and with less drips everywhere.
