I dyed my mom's hair

Today, I helped my mom dyed her hair with a mixture of natural herbs, lemon juice, olive oil and coffee. The reason we needed to add lemon juice, olive oil and coffee is for the vitamin C, for the "shine and cashmere touch" and the colour of the dye. It was very hard at first because it was a little thin for me to apply to her hair, so it kept on dripping down onto the ground making the bathroom floor very very messy. But after two hours, it came out pretty well. Right now, I think that the colour is really similar to the one mom used to use. The "color" that my mom used before to dye her hair. (Which is really bad for the hair.)
