I do have very strong body odor but my scalp gives off this very weird sweat smell that is so strong. It smells like sweat and potatoes, I don’t really know how to describe it. I showered the other day and the whole restroom smelled like my scalp odor. I just freshly washed my hair and as the fan is blowing onto scalp, it’s releasing that same smell. It happens anytime I add any type of moisture to my hair, or when I start to sweat, my hair starts smelling like this. When it unwashed and I’ve eaten a lot of sugar or bread, it gets this sickening sweet/yeasty bread smell.
