Attention all nail enthusiasts! Did you know that certain nail defects might be a sign of underlying health issues? Let's dive in and learn more!

1️⃣ A brown vertical stripe on your nail could indicate melanoma, the deadliest form of skin cancer. It doesn't always appear as a mole or dark spot; it can start in the nail too! Hormones and some medications can also cause pigmented lines, but be extra vigilant for nail cancer symptoms. If you have brown nails and the color change is round rather than linear, it might be another condition, like psoriasis.

2️⃣ Brittle nails? This common issue can arise from poor nutrition or exposure to chemicals. If you lack certain nutrients, your body doesn't have the materials to create healthy nails. Brittle nails can also point to iron-deficiency anemia or thyroid disorders. Limit your exposure to harsh chemicals, as they can contribute to nail breakdown. Contrary to popular belief, calcium doesn't play a role in strengthening nails – that's for bones! Nails are made of keratin, a protein. Ensure you follow a well-balanced diet with adequate protein.

3️⃣ Yellow nails that grow slowly and are quite thick might be connected to lung problems, and they can be excessively curved to the point of separating from the nail bed.

4️⃣ Infected, inflamed skin around the nail is called paronychia and can be caused by pushing back the cuticle. The cuticle tightly adheres to the nail and prevents bacteria, fungi, yeast, and mold from getting under the nail and causing infection. Your doctor may prescribe antibiotics or other medications to address this issue.

5️⃣ Multiple horizontal dents on the thumbnail are a classic sign of a habitual deformity where people chronically rub or pick at the thumbnail cuticle with the index finger during nail formation. This results in one or more wavy, horizontal indentations on the thumbnails, resembling a washboard.

6️⃣ Small white spots on the nails? Many people think these spots are related to vitamin deficiencies, but that's a myth! The condition, called punctate leukonychia, is actually associated with minor trauma during nail formation. Over time, the spots will disappear as the nails grow out, but it takes about 6 months for a new nail to grow from start to finish.

Remember, if you notice any concerning changes in your nails, it's always best to consult with a healthcare professional. Take care of your nails, and they'll take care of you!
