Hello, the top brands of underarm deodorant have aluminum chlorohydrate which is a neurotoxin and is believed to contribute to alzheimers, organ damage and a range of other diseases. I've tried all the supermarket brands of aerosol deodorant for the genital region and they didn't work. "natural" deodorants have potassium alum rather than aluminum chlorohydrate which is not as bad but still it's aluminum. I've also tried lavilin and natures gate natural deodorants meant for the underarms but they didn't work and the natures gate one left me feeling extremely sick at the end of the day and I almost passed out. I've tried tea tree oil creams, zinc oxide, basically everything.
