How Can I Darken My Highlights Naturally?
There are several ways to darken highlights naturally. You can use coffee, tea, or black walnut to make a hair rinse. Brew a strong pot of coffee or tea and let it cool. Pour it over your hair and let it sit for 20 to 30 minutes before rinsing it out. For black walnut, boil the hulls in water for an hour, cool the liquid, and apply it to your hair for about 15 minutes before rinsing. Another option is to use henna, which can darken and condition your hair. Henna is a natural hair dye and can be used on its own or mixed with other ingredients like coffee or beet juice for a darker shade.
