Allergic Reaction to Deodorant!?!?!?!?

Lately I have been having an allergic reaction every time I use my deodorant. When this happens I get a very bad rash that doesn't go away, till I stop using the deodorant for a couple of days. So what I did last night was make a batch of homemade deodorant to use to see if it helps. And I'm only one day in and I can see a difference. I have not had any body odor from my underarms at all today, and I was pretty busy around the house. The recipe is as follows:

1/4 c. Coconut oil
1/4 c. Cornstarch
1/4 c. Baking Soda

*Mix all ingredients in a small bowl with a lid till creamy. Store with lid on, and apply to underarms as needed.*

I have not noticed any shirt staining from the oil, but be cautious with certain fabrics. I wore an old t-shirt today just in case there would have been staining. And there was none. ; )

Blessings to all,
