Nail root whitening is not necessarily gray nail, but may also be related to the lack of trace elements, nail trauma and other factors, and may even be just a circle of health.
1. Gray nail: it is the common name of onychomycosis, related to fungal infection, which can be manifested as thickening of nails, discoloration of nails as well as fingernail shells and other phenomena in the clinic, and it can be diagnosed through fungal microscopy to find mycelium and spores.
2. Micronutrient deficiencies: calcium, zinc, iron and other micronutrient deficiencies may also lead to nail color changes.
3. Nail trauma: After the nail bed or nail plate is damaged, the subsequent growth of the nail may change in color or shape.
4. Circle of Health: Also known as the finger crescent, it is a white curved circle located at the root of the nail, which is actually the nail that is not fully keratinized.
When there is an abnormal change in the color of the root of the nail, it is important to seek prompt medical attention and an interview with a medical professional.
