I grew up using either a Dove or Secret deodorant and love how amazing they smell. I was recently told about aluminum free deodorant and why it is important to use. It was a little hard for me to switch from my holy-grail products that I would find anywhere- to products that I now have to get online or at Whole Foods. I did some research to find out more on aluminum and I found that it is so dangerous because it can increase chances of a person getting breast cancer. According to many studies, breast cancer is usually found in the upper and outer part of the breast, where deodorant is applied. Although it is not a guarantee that aluminum will cause breast cancer, it is good to take the small extra measure and switch out deodorant for one without aluminum. But of course, it is more important to address the real breast cancer risks and eat healthy, exercise, and take care of yourself. The aluminum free deodorant is just a little easy safety measure. A few options that I like to use are: Jason Dry Spray Deodorant in Soft Rose, Jason Deodorant Stick in Calming Lavender, and Soft&Dri Powder Fresh Deodorant Stick.
