Hi, I'm Amelia and I'm going to talk to you about ways to remove product build up from your hair. The easiest way would be to go get a clarifying shampoo and some of them come in vary and strengths. Depending on how much product do you use, if you've got short hair, spiky hair, you use a lot of product everyday, you probably want to use a clarifying shampoo about once a week. If you are just kind of occasionally bringing products to chlorine out, then you probably only want to use it maybe once every two weeks, maybe once a month. You know best on how much product you need or you use and how much clarifying you're going to have to do. If you can't get a clarifying shampoo, another thing that works well is baking soda and water. And you would actually just apply that to your hair, make like a light paste, apply that to your hair and shampoo it in. You could even add it in to a little bit of your shampoo, emulsify it through the hair, let it sit for a little bit and then you could finish it off with a little bit of apple cider vinegar and that will actually add a lot of shine and also remove the coating of any products. So those are some ways that you can remove product build up from your hair.
