2 for 1 Haircoloring

I have short thick graying hair that grows very fast so I have to color every 4 to 6 weeks. To save on haircolor I only use half each time. Just save the applicator bottle and use your own disposable gloves. It’s plenty of color to do my roots and then blend through to the ends. The haircolor I use is about $8.00 a box so I get 2 colorings for $4.00 each.
