Fingernails Splitting Lengthwise vs. Peeling in Layers
Lengthwise splitting and layered peeling can both be described as brittle nails, but they do not look the same. This comparison helps you describe what you see and choose sensible protection.
Lengthwise splits run in the direction of growth; layered peeling usually separates thin horizontal layers at the free edge. Both benefit from protection, but persistent deep or single-nail changes need assessment.
Clinicians may call lengthwise brittle splitting onychorrhexis and layered splitting at the edge onychoschizia. The two patterns can occur together.
Repeated water exposure, solvents, detergents, trauma, picking, aggressive filing and ordinary aging may contribute to brittle-nail patterns.
Describe the direction and location of the change, protect the nail from further stress and avoid treating a ridge as if it were a loose nail layer.
