When it comes to choosing the perfect manicure, gel nails and Shellac nails are two of the most popular options available. Both offer long-lasting wear, vibrant colours, and a sleek finish, but they’re not quite the same. Understanding the differences between these nail treatments can help you or your clients make the best choice based on preferences and nail health. Whether you’re a nail technician or someone exploring options for your next manicure, this guide will help you navigate the key distinctions between gel nails and Shellac.
What Are Gel Nails?
Gel nails are a type of nail enhancement created by applying a gel-based polish that is cured under a UV or LED lamp. They offer durability, flexibility, and a glossy finish, making them an excellent choice for clients who want their manicure to last up to three weeks without chipping.
Gel nails are versatile and can be used on natural nails, extensions, or overlays, such as BIAB (Builder in a Bottle), which strengthens the natural nail while providing a smooth base for the gel. Gel polish is available in a wide range of colours and finishes, including glossy, matte, and glitter.
For nail technicians, learning to perfect gel nail application is essential. Many online beauty courses include modules on gel techniques, teaching you everything from proper preparation to curing for a flawless finish.
What Are Shellac Nails?
Shellac nails are a specific type of gel polish created by CND (Creative Nail Design). They combine gel and traditional nail polish, offering the benefits of both: the durability of gel and the ease of removal of traditional polish. Like gel nails, Shellac requires curing under a UV or LED lamp.
While Shellac is less flexible than traditional gel polish, it is gentler on natural nails. Its thinner application makes it ideal for clients who want a more natural look while still enjoying the benefits of long-lasting wear. However, the brand’s limited colour palette may not appeal to clients seeking a wider range of options.
Nail technicians can enhance their expertise in Shellac application by enrolling in online nail courses, which cover proper curing, layering, and removal techniques.
Key Differences Between Gel Nails and Shellac
-
Formulation and Finish
-
Gel nails use a thicker gel polish, providing a durable and glossy finish that is ideal for clients who need a manicure that withstands daily wear and tear.
-
Shellac combines gel and traditional nail polish, creating a thinner and more natural-looking finish. It’s perfect for clients who prefer subtle, understated nails.
-
Durability
-
Both gel and Shellac nails last for up to two to three weeks without chipping, but gel nails tend to be slightly more robust, making them better suited for clients with active lifestyles.
-
Shellac is durable but may be more prone to chipping if exposed to harsh conditions.
-
Removal Process
-
Gel nails require soaking in acetone or professional-grade removal techniques to avoid damaging the natural nails. Improper removal can weaken nail strength.
-
Shellac nails are easier to remove and typically cause less damage to natural nails, making them a gentler option for clients concerned about nail health.
-
Colour and Customisation
-
Gel nails offer a vast array of colours, finishes, and design options, including glitter and intricate nail art.
-
Shellac has a more limited colour range but is available in classic, timeless shades that suit most clients.
Which Is Better for Nail Strength?
For clients focused on improving nail strength, the choice between gel and Shellac depends on their nail condition and lifestyle. While both options protect the nails from daily wear, Shellac’s thinner application and gentle removal process make it less likely to cause damage.
However, for clients with weak or brittle nails, using BIAB under gel polish can provide extra strength and support. BIAB acts as a protective layer, helping natural nails grow stronger while maintaining a polished appearance.
If you’re a nail technician looking to expand your services, consider exploring online beauty courses that include BIAB application techniques to cater to clients with fragile nails.
Cost and Accessibility
Both gel and Shellac nails are affordable and widely available, though Shellac may cost slightly less due to its thinner application. Clients often choose Shellac for its convenience and quicker removal process, while gel nails are preferred for their versatility and customisation options.
When to Choose Gel Nails
-
If clients desire bold designs, intricate nail art, or dramatic finishes.
-
For clients with an active lifestyle who need maximum durability.
-
When pairing with overlays like BIAB for extra strength and protection.
When to Choose Shellac Nails
-
If clients prioritise a natural look and feel.
-
For clients who prefer gentler treatments for their natural nails.
-
When quick and easy removal is essential.
