Why we love it: We would never include an ingredient that is anything other than helpful to your luscious locks, and that’s why we want to bust any myths you may have heard about dimethicone. So, what does 350 mean? It just indicates the viscocity of our product. We use this in our simple sealant –because the last thing you put on your hair shouldn’t feel tacky to the touch. Dimethicone gives our products a luscious, slippery feel that smoothes and locks in moisture – and you can expect just that from our Simple Sealant. Silicones in beauty or haircare products have a good deal of misinformation floating around the ether recently, and we want to assure you that dimethicone has been thoroughly studied and confirmed safe and effective from scientists and experts around the world.
