She's also just launched a super cool Nail Transformations collection for MAC, consisting of top coats that transform (see what they did there?) your nails, by making them darker, creating a leather effect or adding a shimmer.
So you can say she knows a thing or two about nails. Who better to share her tips on how to take care of your nails.
Use a good nail oil
"f you do nothing else with your nails, it's worth using nail oil, at least once a day if not more often. Preferably at the end of the day so you're not washing it straight off.
Just put a little blob on each cuticle and rub it quickly with your thumb. That will also make your cuticle shrink and stop it from overgrowing. It will go underneath naturally. And it doesn't matter if you've got nail varnish on."
File your nails once a week
"With an emery file, just take the edge off every week. It needs to be a very fine emery board, as a harsh one will actually cause the nail to split and peel. The point of that is exactly like trimming your hair for split ends.
Because on the very edge of your nails, there will be little splits there that you can't feel, and as soon as that happens, water gets inside and then that will lead to peeling. You don't have to make them shorter, just take the edge off."
Use hand cream
That's different from oil, but it's just as good for the nails and skin.
Don't take a break between nail polish poses
"If you've got weak nails or peeling nails, then keep them covered with nail polish.
If it's not a colour, that's fine, just put a clear gloss on, because that actually protects them. Your nails don't need a breather, they don't need a rest. Keeping them covered them is protecting them from water, which the harshest thing of all for nails, and you can't avoid water."
Don't use too much nail polish remover
"Don't use a solvent. Don't remove polish too often. Some people love changing nail colour every couple days, but doing that is too drying for the nails. Everyone knows you put conditioner on after you wash your hair, but nobody thinks about doing it for nails.
Change your nail polish if you have to, but soak your nails in oil to put the conditioner back in."
