Hair Dye Household Hazardous Waste HHW must be dropped off by appointment – click for more info. No Dye Down the Drain Because most hair dye contains harmful chemicals like p-Phenylenediamine (PPD), it should not be dumped down the drain. In addition to contaminating our waterways, it can harm aquatic life and other wildlife. No Chemicals? Garbage OK If the hair dye does not contain chemicals like PPD, place it in the garbage. Hair Developer is Hazardous Waste Dispose of your hair developer just like your chemical hair dye – as hazardous waste. Recycle Box and Instructions Place the paperboard packaging that the hair dye comes in, as well as any paper instructions in your recycling. Ways to Reduce Switch to a Natural, Nontoxic Dye Opt for a natural, nontoxic dye as opposed to a synthetic chemical dye. It will be gentler on your hair and the environment. Ways to Reuse Non-Peroxide Hair Dye and Peroxide OK to Reuse You can save and reuse leftover hair dye and/or peroxide if it’s not mixed together. Give Away Unused Dye If you have unwanted, unopened hair dye, give it away to someone who will use it. Sometimes women’s shelters and assisted living facilities accept donations of hair dye.
