Wrong choice! Over time, this irritation only made the situation worse. See, as I would later learn, I made the all-too-often mistake of trying to solve the symptom, not the cause. So what was the cause of these little flakes? It pains me to say this, but dandruff. Yes, the same dandruff that plagues the scalp. The triggers are all the same as other forms of eczema: cold weather, dry environments, irritating personal care products, or an allergy, but dandruff has a few other more specific triggers, like oil buildup (the yeast feeds on oil) or microbiome-disrupting washes.
