Onychorrexis: What Are the Causes?
(1 minute read)
The Chelsea Clinic | Chiropodists and Podiatrists | South Kensington
Have you noticed ridges, splitting, or brittle patches on your toenails? These changes might not just be cosmetic — they could indicate a condition called onychorrexis. At The Chelsea Clinic, we frequently help clients understand and treat this common nail disorder.
Onychorrexis: What Are the Causes?
Onychorrexis refers to the presence of longitudinal ridges or splits in the nail plate — often running from the base to the tip of the nail. It can affect both fingernails and toenails, but in podiatry, we commonly see it on the feet due to pressure, footwear, or underlying health issues.
Onychorrexis and reasons for this condition
There are several reasons why nails may become ridged, brittle or split:
-
Age-related changes: As we get older, nails naturally become drier and more fragile.
-
Trauma or repetitive pressure: Tight shoes or impact injuries can weaken the nail matrix.
-
Nutritional deficiencies: Low levels of biotin, iron, or zinc can affect nail health.
-
Chronic exposure to moisture or chemicals: Overwashing, nail polish removers, or harsh soaps can dry out the nails.
-
Skin conditions: Eczema, psoriasis, and lichen planus can all impact nail texture.
-
Systemic illness: Conditions such as thyroid dysfunction, diabetes, or circulatory issues may also manifest in nail changes.
What Are the Symptoms?
-
Long vertical ridges in one or more toenails
-
Nails that split easily or peel in layers
-
Brittleness or flaking
-
Discomfort if the nail becomes snagged or catches on fabric
Is Onychorrexis Harmful?
On its own, onychorrexis is usually not dangerous — but it can be a sign of something else going on beneath the surface. At The Chelsea Clinic, our podiatrists will assess whether your nail changes are due to simple mechanical stress or an underlying medical condition.
