Nails without luster may be caused by long-term manicure, malnutrition, fungal infection and other reasons.
1. Long-term manicure: If you do manicure for a long time, you will polish your nails to make them thinner, thus making them look shineless, which is a normal phenomenon.
2. Nutritional deficiencies: If the body is malnourished due to picky eating, improper diet, etc., it will also lead to the appearance of nails without luster, uneven surface and not smooth and other symptoms.
3. Fungal infection: If the whole nail is dull and accompanied by thickening of the nail, hollowing in the middle of the nail and separation of the nail bed, it may be due to fungal infection.
If your nails are dull for a long period of time, we recommend that you go to the hospital and have your nails treated under the guidance of your doctor.
