Place 2 cups (470 mL) of leave-in conditioner into a bowl. Stir in 2 tablespoons (10 g) of coffee grounds and 1 cup (240 mL) of room-temperature brewed coffee. Apply the mixture to your hair, wait 1 hour, then rinse it out with warm water. To help set the color, rinse your hair with apple cider vinegar afterward, then let your hair air dry.  The stronger you brew your coffee, the darker the color will be. Espresso would be even better. Do not add any milk or sugar to the coffee. For best results, use white-colored conditioner. You can also substitute plain conditioner or a hair mask. This method may be able to dye lighter hair colors a dark shade of brown. This is not permanent and will only last 2 to 3 washes. You can reapply the dye more often to prolong the effect, however. Brew 3 to 5 tea bags in 2 cups (470 mL) of water. Allow the tea to cool completely before using it on your head. Pour the tea over your hair, or mix it with 2 cups (470 mL) of conditioner, and leave it in your hair for 1 hour before rinsing it out with warm water. Like coffee dye, this will only last about 2 to 3 washes.  Use black tea if you want to darken your hair or cover up grays. Use rooibos or hibiscus if you want to enhance red tones. Try chamomile tea if you want to brighten up blonde hair or lighten light brown hair. Simmer 1 to 2 tablespoons (4.5 to 9 g) of your desired dried herb in 2 cups (470 mL) of water for 30 minutes. Strain the solution into a spray bottle, then mist it onto your hair until it's damp. Just like coffee or tea dye, this is not permanent and will only last about 2 to 3 washes.  Use calendula, hibiscus, marigold, or rosehips to bring out red tones. Let it air dry in the sun, then rinse it out using warm water. For dark hair, try crushed walnut shells, nettle, rosemary, or sage. Leave it in your hair for 1 hour before rinsing it out with warm water. You don't need the sun for this. To brighten blonde hair, try calendula, chamomile, marigold, saffron, or sunflower. Pour it over your hair, let it air dry, preferably in the sun, then rinse it out using warm water. Simply apply 1 cup (240 mL) of beet or carrot juice to your hair, then cover your hair with a plastic shower cap. Wait at least 1 hour, then rinse your hair with warm water. Rinse it again with apple cider vinegar to set the color.  Beet juice is good for strawberry blonde, deep red, or auburn tones. Carrot juice is better if you want something reddish-orange. If the color is not dark enough, repeat the process. Keep in mind that it is not permanent and won't last more than 2 or 3 washes.
