Article: Avoid handling your newly-dyed facial hair too much, as the friction may rub off the coloring. Instead, let the water run through your beard and comb it out gently with your fingers. Most of the time, a simple rinse will be enough to keep your beard clean and your color intact.  Hot water is more likely to cause fading than cooler temperatures.  Wait until your beard is dry before brushing it or applying any other products, like lotions or oils. Invest in shampoos and conditioners formulated for use on color-treated hair. These are designed to clear away dirt and oil without affecting the hair's color. You'll be able to find these types of products in the beauty aisle of most major supermarkets and pharmacies.  Stay away from cleaning products containing harsh chemicals. If you're used to shampooing and conditioning your beard every time you shower, consider cutting down to once or twice a week. Most dyes are non-permanent, which means they'll need to be reapplied when they begin to fade. For follow up colorings, you'll probably only need to go through a single round of coloring. Treating your beard regularly will keep it looking thick, full and youthful.  Aim to dye your beard every 3-6 weeks, or sooner if needed.  Because of how fast facial hair grows, your beard's roots may need to be touched up more frequently than the rest of it.

What is a summary?
Rinse your beard lightly when you shower. Use color protecting products. Touch up your beard periodically.
