Natural Deodorant

my armpits are EXTREMELY sensitive. i’ve tried 10+ natural deodorants (toms sensitive skin, normal toms, crystal, nubian heritage, schmidts sensitive, normal schmidts, etc. etc. etc.) and they have all made my armpits break out in a very very itchy rash. i’m at a loss. i can’t find anything that works for me and my armpits are in so much pain.

I know i’m allergic to the aluminum & the baking soda for sure.

please help😪
