Vertical lines in the nail plate could indicate which of the following?

Vertical lines in the nail plate are often referred to as striations or ridges, and they can be indicative of underlying health issues. These lines may signal a variety of conditions, including nutritional deficiencies, aging, or systemic diseases. As the body ages, the production of natural oils decreases, and this can lead to the development of vertical lines in the nails. Additionally, certain health conditions, such as eczema or psoriasis, can also affect the appearance of the nails, resulting in vertical ridges.

Understanding this aspect of nail health can be crucial for cosmetologists, as they are often the first to notice changes that could reflect the client's overall health. This knowledge empowers beauty professionals to consult clients and potentially recommend them to seek medical advice if such changes are observed. It underscores the importance of a holistic understanding of beauty that encompasses both aesthetic and health considerations.
