Your nails can reveal important clues about your overall health. Lines or “stripes” on nails are not just cosmetic—they can signal aging, stress, or underlying issues. In dermatology, nails are often seen as a reflection of what’s happening inside the body.

Vertical ridges are the most common and usually harmless, often linked to aging. However, if they appear suddenly or come with brittleness, they may point to nutritional deficiencies such as low iron, magnesium, or protein. These changes suggest the body may not be getting enough essential nutrients.

Horizontal lines, known as Beau’s lines, are more serious. They indicate a توقف (pause) in nail growth caused by major stress, illness, or trauma. These lines act as a timeline, showing when the body experienced a significant disruption.

The good news is that nail health can improve with proper care. A balanced diet rich in vitamins (like biotin), hydration, and protecting nails from harsh chemicals can help restore their strength. Paying attention to these signs early can help you address potential health issues before they become more serious. READ MORE BELOW
