Write an article based on this "Purchase a blue or purple toning shampoo. Get your hair wet with hot water. Apply the shampoo to your hair, starting from the roots. Allow the shampoo to sit in your hair, if needed. Rinse the shampoo out with cool water. Dry your hair. Use the shampoo once per week if the brassiness comes back."
article: Purple shampoo is the most common, but something that is blue-tinted would work even better. Blue sits opposite orange on the color wheel, so a blue-tinted toning shampoo will be more effective at balancing out the orange.  This method is recommended for those who bleached their hair, and hot roots. Be aware that this method will also tone the rest of your hair as well. If you can't find a toning shampoo, make your own by stirring a few drops of dark blue or purple dye into white conditioner. You want violet/lavender color. You can do this by leaning over a sink and running water over it, but it would be even easier to just undress and step into the shower. You can even combine this method with your evening or morning shower. Using hot water is important as it will open up the hair shaft. This will make it easier for the hair to absorb the color in the shampoo. Massage the shampoo into your roots first, then work it through the rest of your hair. Because this shampoo contains so little color, you can use it like you would any other shampoo and not worry about it staining your hands. This depends on the brand you are using, so check the label. Some types of shampoo require you to rinse the dye out immediately, while others recommend that you leave it on for 10 to 15 minutes. Because this shampoo is so gentle, however, you can leave it on for longer depending on the damage. You can leave the shampoo on for up to an hour. If you need to step out of the shower, tuck your hair under a shower cap. Keep rinsing until the water runs clear. You can follow up with a sulfate-free conditioner meant for color-treated hair. If you made your own toning shampoo with white conditioner, skip the extra conditioner. Using cool water will help seal the hair shaft and lock in the color. It will also help make your hair shiny and smooth. You can let your hair air dry, or you can apply a heat-protectant product and speed things up with a hair dryer. Your roots should be a cooler color than before. If you bleached your hair all over, they might be a light orange color. Sometimes, chemically-treated hair just goes brassy over time. If this is the case for you, you'd want to use the toning shampoo once per week.

article:
To make your own pH indicator, you will need half a head of red cabbage, a knife, water, a stove, and a medium saucepan. Red cabbage contains a chemical called anthocyanin that changes color based on acidity. By boiling the cabbage, you can make a pH indicator from this chemical and test the acidity of your rain. Adult supervision is recommended for this because you will need to handle a hot stove and a sharp knife. . You want about 2-3 cups of red cabbage cut into small pieces. If you are young, have an adult help you with this step to avoid potential injury. The exact amount of cabbage is not important, so just cut up half of the head of cabbage. Place the chopped cabbage into the saucepan and add enough water to cover the cabbage. Put the saucepan on the stove and bring the water to a full boil. Once the solution boils, turn the heat off and let the water cool to room temperature.  Have a parent help with this step to avoid injury when using the stove and working with boiling water. You should notice that the water is now purple. Pour the cabbage and water mixture through a strainer into a bowl. The purple water (the indicator) is currently neutral because the water from your tap is neutral. In the presence of an acid, the indicator turns pink. In the presence of a base, the indicator turns blue. You can refrigerate the solution until you need it. To make sure the indicator is working properly, you can test it using baking soda and vinegar. Put 1 teaspoon (~5 mL) of the cabbage water into two small, clear glasses. Add a teaspoon of vinegar to one glass and a teaspoon of baking soda to the other.  Vinegar is acidic, so the water will turn pink. Baking soda is basic, so the water will turn blue. Collect some rainwater in a clean, plastic container. Pour 1 teaspoon of cabbage water into a small, clean glass. Add a teaspoon (~5 mL) of the collected rainwater to the cabbage water. The water should turn pink because all rain is slightly acidic. The deeper the pink, the higher the acidity in your area. This method will not tell you the exact pH of the rain, but will give you an idea of how acidic it is. If you are traveling, you can compare rain from different areas such as different cities, state or province, or even countries and see if the deepness of the pink changes.
