You’re sitting in the salon chair, nails prepped and ready, and your technician asks the question: gel or Shellac? You smile, whilst having absolutely no idea what the difference is. Don’t worry, we’ve all been there.<\/p>\n\n\n\n

Gel delivers durability and strength, whilst Shellac offers a lightweight, natural finish that feels like you’re wearing nothing at all. This guide breaks down everything you need to know, from how the formula’s feel on your nails to how long they last, so you can walk into your next appointment knowing exactly what to ask for.<\/p>\n\n\n\n

What is gel polish?<\/h2>\n\n\n\n

Gel polish<\/a> is a long-wear nail colour that cures under UV or LED light, forming a chip-resistant, glossy finish. Its acrylic-based formula is thicker than regular polish and often lasts up to 21 days with minimal chipping (yes, even through a post-party washing-up marathon).<\/p>\n\n\n\n

What sets gel apart is its buildable, dense formula that reinforces weak nails and allows for extensions. Whilst gel and Shellac share a similar application process, gel’s viscosity and structure give it a different personality entirely.<\/p>\n\n\n\n

Types of gel polish explained<\/h3>\n\n\n\n

Hard gel (the file-off kind) creates strong extensions and builds length for those wanting talons without acrylics. Soft gel, however, is more flexible, ideal for overlays on natural nails that need protection without full armour. Builder gels are thick and perfect for sculpted tips that still move with your natural nail.<\/p>\n\n\n\n

How gel polish is applied<\/h3>\n\n\n\n

Your nail technician lightly buffs the nail, adds a base coat, applies 2-3 layers of colour (curing each one under an LED or UV lamp), then finishes with a top coat for shine and protection. The whole process takes around 30-45 minutes. There’s a satisfying rhythm to it, and you walk out with nails that look freshly done for weeks.<\/p>\n\n\n\n

What is Shellac?<\/h2>\n\n\n\n

Shellac<\/a> is a CND-brand hybrid polish that combines gel’s durability with the ease of regular polish. It’s applied in thin layers, cures under a lamp and leaves a glossy, lightweight finish. Shellac is exclusively produced by CND and focuses on colour and shine, not length. When someone says they’re getting “shellac” they might mean any gel polish, but true Shellac is a specific product.<\/p>\n\n\n\n

The history of Shellac by CND<\/h3>\n\n\n\n

Launched as a lighter, easier-to-remove alternative to thick gel, Shellac’s hybrid formula and two-week resistance to chipping quickly made it popular in salons worldwide. It bridges the gap between regular polish that chips within days and gel that lasts for weeks but can feel heavier on the nail.<\/p>\n\n\n\n

How Shellac differs from regular nail polish<\/h3>\n\n\n\n

Shellac offers a flexible, chip-resistant finish that stays shiny for up to two weeks. Its thin application helps natural nails flex whilst maintaining a polished look. Most people can type, text and go about their lives without that slightly odd awareness of having “something” on their nails.<\/p>\n\n\n\n

Application and feel: gel vs Shellac side by side<\/h2>\n\n\n\n

Gel<\/a> creates a thick, substantial layer that protects brittle nails. Shellac<\/a> feels weightless and natural, almost like you’re not wearing polish at all. So, while Shellac is like your nails but better, gel is the go-to for reinforcement.<\/p>\n\n\n\n

Gel requires more careful layering to prevent bubbles (your technician will know the drill). Shellac’s thinner formula cures a tad faster and is more forgiving during application.<\/p>\n\n\n\n

Thickness and texture comparison<\/h3>\n\n\n\n

Gel’s thicker consistency shields and supports weak nails. If your nails bend like paper or snap at the slightest knock, gel is your friend. Shellac’s thin application suits short or natural nails where flexibility matters, moving with your nail rather than sitting on top.<\/p>\n\n\n\n

Professional application<\/h3>\n\n\n\n

A salon technician is an expert in layering and curing, and this is what makes the difference between a manicure that lasts and one that peels within days. Genuine CND Shellac is salon-exclusive, so if you want the real thing, booking in with a pro is the way to go.<\/p>\n\n\n\n

Durability and longevity: which lasts longer?<\/h2>\n\n\n\n

Gel polish lasts up to three weeks or more with proper care, whilst Shellac typically holds strong for 10-14 days. Gel’s thicker formula offers increased protection and longevity. Shellac may be a touch more sensitive to frequent hand washing or cleaning products, but it often keeps its glossy shine for the full two weeks even with minor wear at the tips.<\/p>\n\n\n\n

What affects how long your manicure lasts<\/h3>\n\n\n\n

Frequent hand washing swells the nails, loosening the adhesion. Meanwhile, cleaning products weaken the bond between polish and nail plate. Daily habits like typing, picking or scratching can also jeopardise your mani. Some people naturally get three weeks from gel whilst others struggle past ten days, and lifestyle is usually the culprit.<\/p>\n\n\n\n
