I recently heard about hair touch-up sticks (color sticks) as a quick and easy way to cover gray hair. How do they work? You have to wet the color stick and then brush over the offending strands. Then wait for a few minutes to dry. The color allegedly stays on until your next shampoo. Just perfect for those people who want to cover their roots between coloring appointments. It’s not very expensive also, just costs around $6 and lasts for more than 6 months. It is available in colors ranging from light brown to black. Select a shade that closely matches your hair-color and camouflage your gray hair.
