Ageing
Yellowing of the nails can be caused by a number of factors, including the chemicals in nail polish, especially with brighter or darker colours such as red, pink, orange or black.
In some cases, yellow nails can be a sign of a more serious underlying health condition, such as diabetes or a fungal infection called onychomycosis. In rare cases, it can be a sign of a disorder called yellow nail syndrome (YNS), which causes yellow, curved, thickened nails that grow slowly, along with other symptoms like respiratory problems. If you suspect a medical condition, it is advised to consult a doctor.

Nail polish
Yellow toenails can be caused by a number of factors, including nail polish. If you notice your toenails turning yellow, it could be due to the type of nail polish you are using. Some polishes, especially those in brighter or darker colours such as red, pink, orange or black, can cause a yellowish discolouration. This is because these colours tend to have more pigment, which can stain the nails over time.
To prevent yellow nails caused by nail polish, it is recommended to use a base coat before applying colour. A base coat acts as a barrier between the nail and the polish, helping to prevent discolouration. It is also important to allow the nails to breathe between polishes, so try to go polish-free for a few days every now and then.
If you are concerned about yellow nails, it is best to consult a doctor as it could be a sign of an underlying health condition. Yellow nails can sometimes indicate a fungal infection, such as onychomycosis, which is more common in adults. In rare cases, it could be a sign of yellow nail syndrome (YNS), a disorder characterised by yellow, curved, thickened nails that grow slowly. YNS can also cause respiratory problems and other symptoms such as ridges or indentations in the nails.
While ageing is one of the most common causes of yellow nails, it is important to be mindful of the products you are using and to consult a doctor if you have any concerns.
