Baking soda and developer is a combination that can be used to remove hair dye. Baking soda is a mild abrasive that can help to lift the hair dye from the hair shaft, while the developer helps to break down the dye molecules. This combination can be effective at removing both permanent and semi-permanent hair dye.
There are a few things to keep in mind when using baking soda and developer to remove hair dye. First, it is important to test the mixture on a small area of skin before applying it to the entire head. This will help to ensure that you are not allergic to the mixture. Second, it is important to follow the instructions carefully and to not leave the mixture on the hair for too long. This can damage the hair.
