- Prepare to dye the hair
Apply a thin layer of Vaseline around the beard to keep the dye from making contact with the skin. The dye kit should include plastic gloves to keep the dye from contacting the hands. Make sure all surfaces are covered well to avoid discoloration.
- Apply the dye
Using the brush supplied in the kit, test a small patch of facial hair to see how it reacts to the dye. If satisfied, continue applying the dye to the beard. Periodically check to see how the dye is affecting the color of the beard and apply a second layer if needed.
- Rinse the facial hair
Once satisfied with the results of the dye, rinse the facial hair in warm, soapy water. Continue rinsing the dye from the hair until the water is clear. If you're not satisfied with the new color of the facial hair, it can removed by using a clarifying shampoo.
