You need a spray bottle that holds at least 16 ounces (473 ml) While fresh lemon juice is best for the spray, you can use a bottled variety as long as it’s pure juice. Because lemon is so acidic, it can dry out your hair even when it’s diluted with water. If you have dry or damaged hair, add 2 to 3 teaspoons (10 to 15 g) of your conditioner or a hair oil to the lemon mixture for extra hydration.
If you prefer to use the lightening spray to create a highlighted effect, only apply the spray to strategic sections of your hair.
The longer time you spend in the sun, the lighter your hair will end up. If you don’t want to sit in the sun, place a shower cap or plastic wrap over your hair after you spray it to generate some heat.
Make sure that the spray bottle holds at least 8 ounces. Like the lemon juice, chamomile can help naturally bring out the lighter tones in hair.
Cinnamon contains natural peroxide, and honey undergoes a chemical reaction when mixed with water that helps it serve as a lightening agent. Coconut oil provides moisture to help counter the drying nature of the lemon juice. If your hair is particularly dry and dehydrated, you may want to add an extra teaspoon of coconut oil for a total of 2 teaspoons (9 g).
If you plan to use the lightening spray while you sleep, wear a shower cap to keep your sheets from getting bleached. Rinse the spray out of your hair in the morning. You can give your hair an ombre effect by only applying the spray to the ends of your hair.
You can substitute lime juice if you’re out of lemon juice. Because the spray contains an essential oil, it’s best to use a glass spray bottle. Essential oils can break down easily in plastic containers.
You can find sage essential oil at health food stores and organic grocery stores.
Use the spray every two weeks for brighter, lighter hair. If your hair is extremely dry, use it once every three weeks.
