Microtrauma

Ridges in your nails are usually harmless but can mean different things. Vertical ridges are often a sign of ageing, while horizontal ridges can point to issues like malnutrition, serious nail injury, or Beau’s lines. Beau’s lines are horizontal ridges or dents in one or more of your fingernails or toenails. They’re a sign that an illness, injury or skin condition interrupted your nail growth. Treating the underlying cause will allow new, smooth nails to grow again.

Nail lines are most often associated with microtrauma, such as from a manicure. Lines due to trauma are typically more apparent in the central part of the nail plate; they spare the lateral portion and lie parallel to the edge of the proximal nail fold. Injury to your nails, picking at your nails, or strong chemicals can damage your nail matrix, affecting how your nails grow. The main symptom of onychorrhexis is vertical ridges in your nail.

Dystrophy or disease

Ridges in your nails are usually harmless but can sometimes be a sign of dystrophy or disease.

Nail trauma, such as injury, picking at your nails, or exposure to strong chemicals, can damage your nail matrix, affecting how your nails grow. The main symptom of nail trauma is vertical ridges in your nail. Rather than having a smooth nail, you might have nails with vertical grooves that feel bumpy. Nail pitting, or small indentations on your nail surface, is not generally a symptom of nail trauma. Nail trauma mainly causes vertical ridges and splitting of the nails. Nail pitting is more common with other issues, such as psoriasis, fungal infections, or certain autoimmune diseases. Horizontal ridges in your nails are called Beau's lines.

White nail lines or leukonychia is classified as true or apparent, depending on whether the origin is in the nail matrix or the nail bed. Patients should be instructed to remove nail polish from all nails, as it may camouflage dystrophy or disease of the nail. Photography and careful measurement help document changes over time.

Vertical ridges

Ridges in your nails are usually harmless but can mean different things. Vertical ridges, also known as onychorrhexis, are often a sign of ageing. They can also be caused by injury to your nails, picking at your nails, or strong chemicals that damage your nail matrix, affecting how your nails grow. This can result in vertical grooves that feel bumpy.

While vertical ridges are typically a benign condition, they can be a source of cosmetic concern for some individuals. Additionally, in rare cases, they may be indicative of underlying health issues. For example, vertical ridges can sometimes be associated with nutritional deficiencies, such as a lack of essential fatty acids or certain vitamins and minerals.

There are several treatment options available for vertical ridges. One approach is to focus on improving nail health through proper nail care and hydration. This includes regular moisturisation of the nails and cuticles, as well as the use of nail-strengthening products that contain ingredients like biotin or keratin. In some cases, medical treatments may be recommended, such as the application of topical medications or the use of oral supplements to address any nutritional deficiencies.

It is important to consult with a healthcare professional or dermatologist if you have concerns about the appearance of your nails or if the condition is causing discomfort. They can help determine the underlying cause of the vertical ridges and provide guidance on the most appropriate treatment options.
