Hydrogen Peroxide and water make a great combo for killing and getting rid of mold. Does your shower grout get moldy? Mix 1:2 ration of hydrogen peroxide and water in a spray bottle. Thoroughly coat the surface and let it sit for at least an hour. Rinse well and let dry.
Use a baking soda rinse to get rid of residue and buildup on your hair. Mix 2 tablespoons baking soda with about 1/2 cup of water, then massage the mixture into the hair from the scalp to ends. Let set for 15 minutes, then rinse and wash as usual. Apply twice a month, or whenever your hair needs extra cleaning.
