WHY IS TREATMENT SO IMPORTANT?

The secret to long-lasting shellac isn't just the application. it's what you do in between. Well-moisturised nails and cuticles hold your colour for longer, chip less at the edges, and look better as they grow out. These four CND treatments are the ones worth having at home.

CND™ SolarOil™ | £11.95

The one product every shellac user should own. SolarOil is a lightweight blend of jojoba, sweet almond, and rice bran oils with Vitamin E, designed to penetrate the nail and cuticle rather than just sitting on the surface. Used daily, it keeps the cuticle area moisturised and flexible, which directly helps shellac last longer by maintaining the seal at the nail edge. It's also available as a Care Pen if you want something that fits in your bag.

Best for: daily maintenance, extending shellac wear, dry or damaged cuticles


CND™ RescueRXX™ | £25.95

 

If your nails peel, split, or break at the tip, RescueRXx is the treatment to reach for. It's a keratin-based formula that works by bonding to the damaged layers of the nail plate, helping to stop splitting from travelling further up the nail. Use it daily on clean nails for two to four weeks — it's also the product we recommend using before your first shellac application if your nails are particularly thin or weak. Available as a Care Pen too.

Best for: peeling, splitting or layering nails; nails recovering from gel or acrylic removal


CND™ Cuticle Eraser | £15.95

If SolarOil is the conditioner, Cuticle Eraser is the shampoo. This alpha-hydroxy acid treatment gently exfoliates overgrown or rough cuticle skin, making it easier to push back the cuticle cleanly before application, which is one of the most important steps for getting shellac to sit flush to the nail and last well. Use it before your shellac session, then follow with SolarOil to rehydrate.

Best for: pre-application prep, overgrown or rough cuticles


CND™ Strengthener Rxx™ | £24.95


 

A newer addition to the CND range, Strengthener RXx is a breathable, vegan nail enamel formulated with celery seed extract and Tsubaki oil. It builds thickness gradually over 14 days and smooths the nail surface, making it a good choice if your nails are too weak or thin to hold shellac well right now. It can also be worn alone for a natural, healthy-looking finish, or topped with CND Vinylux Top Coat if you want a little colour without committing to a full shellac application.


Best for: thin, weak or recovering nails; a no-colour treatment between shellac sets
