Which texture in nails is characterized by lengthwise grooves in the plate?

Ridges in the nails are indeed characterized by lengthwise grooves in the nail plate. These can appear as raised lines going from the cuticle to the tip of the nail. Ridges may result from various factors, including aging, nutritional deficiencies, or underlying health conditions. They can be either vertical or transverse, although the term "ridges" typically refers to prominent lengthwise grooves. Understanding this characteristic helps nail technicians identify the condition of a client's nails and provide appropriate care or recommendations.

In contrast, pitting refers to small depressions or indentations on the nail surface, often associated with conditions like psoriasis. Onychorrhexis describes the presence of brittle and split nails, where the edges may break or peel. Furrows usually denote more pronounced indentations or grooves that can run across the width of the nail rather than lengthwise. Each of these conditions has distinct features and implications for nail health.
