Some good dyes for covering gray hair include Revlon ColorSilk, Herbatint Permanent Herbal Haircolour Gel and Umberto Beverly Hills U Color. Dyes designed specifically for covering up gray roots or partial gray coverage include Christian Dior's Mascara Flash for Hair and ColorWow.
Dyes without ammonia are recommended for covering gray hair as these products tend to be less drying. Moisturizing shampoos and other products should also be used in conjunction with hair color, as these prevent color fade and damage to the hair follicle. Individuals with gray hair may find that they need to touch up their roots frequently, as gray hair is more difficult to color closer to the scalp.
