Nail myths "Give nails a break from polish to let them breathe."

Nails do not have a respiratory system so they cannot essentially breathe. In fact, the nail you see is in fact dead. The living part of the nail is found within the matrix which is underneath the base of the nail. 

It is important to remember nail varnish can be very toxic and because of the intensity of the colour and the chemicals this can be massively dehydrating on the nails. This dehydration can affect the nails in various ways, including ridging, scaling, brittleness, discolouration, and it can also cause white flecks to appear on the nail.

Whilst the nails are covered with polish the damage to the nails will continue, but also with the nail covered you cannot see the damage that is being caused so by the time you do see it the damage is done. Polish-free days are essential when looking after your nails as it allows them time to breathe and recover, rehydrating naturally. Your nails will be in much better condition if you take a week between each polish as they will have had enough time to revitalize and strengthen.
