Why is only one of my hand peeling?

If only one of your hands is peeling, it could be due to several factors, such as localized irritation from contact with a specific substance, an allergic reaction, or a skin condition like eczema or psoriasis. Dehydration or excessive washing can also lead to dryness and peeling in one hand, especially if you use one hand more frequently. If the peeling persists or is accompanied by other symptoms, it's best to consult a healthcare professional for an accurate diagnosis and treatment.
