Ridges in fingernails can be caused by various factors, including health conditions, nutrient deficiencies, and improper nail care. Some common causes of vertical and horizontal ridges in fingernails are: Vertical Ridges :
- Aging: Vertical ridges, also known as onychorrhexis, can become more pronounced over time as nails naturally get thinner and more brittle
- Nutrient Deficiencies: A deficiency in vitamins, such as iron, folic acid (vitamin B9), or protein, can lead to vertical ridges
- Health Conditions: Conditions like dry skin, eczema, psoriasis, hypothyroidism, rheumatoid arthritis, and other inflammatory skin conditions can cause vertical ridges
Horizontal Ridges :
- Aging: Horizontal ridges, also known as Beau's lines, can be caused by natural aging
- Nail Trauma: Injuries to the nails, such as closing a door on the finger or dropping something on the nail, can lead to horizontal ridges
- Nutrient Deficiencies: A deficiency in zinc, iron, or protein can cause horizontal ridges
- Health Conditions: Diabetes, thyroid disease, and acute kidney disease can cause horizontal ridges
If you notice ridges in your fingernails and are concerned about the underlying cause, it is recommended to consult a healthcare provider or dermatologist for a proper diagnosis and treatment plan
. In some cases, treating the underlying cause or maintaining proper nail care can help smooth out the ridges
