Super dry skin
Maybe it’s winter – or maybe it’s a thyroid hormone abnormality, says Dr. Chris Adigun, a dermatologist in Chapel Hill, North Carolina, who notes that thinning hair often accompanies this symptom when it’s linked to a thyroid issue. Dry skin paired with seriously peeling nails, meantime, can be a sign of zinc deficiency. In either case, visit your primary care physician, who can identify the cause and a solution, be it supplements or simply lotion.
