I've been told by several hairdressers to not mix bleach in metallic bowlsThey said it quot;deionizesquot; it or somethingBut when they do highlights in salons, how can they wrap the highlights in foil? It obviously works, but it doesn't make sense.
Foil is not the same as metalIt's aluminum and not 100% and alum is different than stainless steel (usually what bowls are) or any other metalI still wouldn't mix in an alumfoil container either but it probably wouldn't hurt itGlass or plastic.
