Nail Furrows, ridges, or corrugations on the nails refer to longitudinal lines or grooves that run along the length of the nail plate. These lines may vary in depth and can be associated with different factors. Understanding furrows, ridges, or corrugations on the nails, their symptoms, and possible causes, is essential to make sure of proper maintenance and to know what artificial nail product if any to use to improve the look of the natural nail once its as recovered as it can be.

Síntomas de surcos, crestas u ondulaciones en las uñas
The primary symptom is the presence of longitudinal lines or grooves on the nail surface. The lines may be fine or more pronounced and can be more noticeable on longer nails. Sometimes we see little ‘bead-like’ defects in the nail plate (see red circle) These nails are generally quite hard and as long as they are not split open you can improve the look of the nail with artificial nail products.
We advise a permanent product that requires a fill (acryl liquid & powder or hard gel) because removing soak off products from ridged nails can cause more problems simply because of the damaged caused trying to scrape the product out of the groves and this damage is not visible until the next time you remove the product. This nail plate developed a surface fungal infection that took a couple of weeks to deal with. (Sorry for the quality of the picture its taken with a very old phone)
Posibles causas:
- Envejecimiento: A medida que las personas envejecen, el crecimiento y desarrollo natural de las uñas puede dar lugar a la formación de crestas o surcos.
- Traumatismo o lesión: Injuries or trauma to the nail bed can cause furrows or ridges as the nails grow.
- Deficiencias nutricionales: La ingesta inadecuada de ciertas vitaminas y minerales puede afectar a la salud de las uñas y provocar la aparición de crestas.
- Condiciones de salud subyacentes: Los surcos o crestas pueden estar asociados a determinadas afecciones médicas, y como tales pueden mejorar o deteriorarse con el paso del tiempo dependiendo de la causa.
