Which is Better: Shellac or OPI Gel Color? Comparing Nail Polish Qualities

Understanding Nail Polish Types


When choosing between nail polish options at the salon, you’ll likely encounter Shellac and OPI GelColor, two popular choices that offer distinct benefits and application methods. Your understanding of each can lead to a more informed decision about your manicure preferences.

Shellac vs. Gel Manicures

Shellac is a branded product by CND (Creative Nail Design) and stands as a pioneer in the category of long-lasting polish. It’s a hybrid that combines the best features of traditional nail polish with gel technology for a high-gloss finish and extended wear time without chipping. Gel manicures, like those offered by OPI GelColor, comprise a thicker, more viscous formula that also cures under UV or LED light and is known for its durability and a wide range of over 140 beautiful colors. Both require professional application and removal, typically at a salon, and offer a more lasting solution compared to traditional nail polish.

Components and Formulas

The formulas for Shellac and gel polishes like OPI GelColor are designed to cater to clients looking for resilience and longevity in their manicure. With Shellac, you expect a quick application process consisting of a base coat, color coat, and topcoat, each of which requires curing under a UV or LED lamp. On the flip side, OPI GelColor’s application involves a similar process but is known for its thicker consistency and vibrant color offerings. Both types contain photoinitiators that require curing to set the polish, but the exact components differ between brands, leading to variations in texture, opacity, and glossiness. It’s important to note that whatever your preference, using acetone is essential for proper removal to maintain nail health.

Application Processes


When selecting between Shellac and OPI Gel Color for your manicure, the application process is a pivotal factor that affects the durability and appearance of your nails. Both processes involve a sequence of steps that require specific products and tools, as well as curing under an appropriate light source to achieve that perfect, long-lasting glossy finish.

Preparation and Tools

For both Shellac and OPI Gel Color, you begin with clean, prepped nails. Your nails should be shaped to your preference, and any non-living tissue should be removed from the nail plate. The essential tools for both systems include:

  • A nail file and buffer
  • Cuticle pusher
  • Cleanser for the nail plate
  • Base coat (specific to the system)
  • Color coat(s)
  • Top coat
  • LED or UV lamp for curing

Shellac boasts a quicker application process, as it requires fewer layers and benefits from a faster curing time under an LED lamp.

OPI Gel Color, in contrast, necessitates a base coat, two coats of polish for a rich color, followed by a top coat. Each layer requires curing under either an LED or UV lamp, with LED lamps generally being the quicker option.

Techniques and Curing

Applying Shellac:

  1. After preparing your nails, apply a thin layer of base coat.
  2. Cure under an LED lamp for 10 seconds.
  3. Follow with a layer of Shellac color coat.
  4. Cure for an additional 2 minutes.
  5. Apply the special top coat and then cure for another 2 minutes.
  6. Wipe nails with a lint-free cloth soaked in alcohol to remove the inhibition layer.

Applying OPI Gel Color:

  1. Start with a base coat, and cure under an LED or UV light as directed.
  2. Apply the first coat of OPI Gel Color, and cure it.
  3. Add a second coat of color and cure again for full opacity.
  4. Finish with a top coat to ensure a glossy finish and cure once more.
  5. Clean the inhibition layer if needed, according to the specific product instructions.

For both systems, professionals in a nail salon use specific application techniques to ensure even coating and edge coverage, optimizing wear and preventing the lifting of the polish. The curing step is crucial; be patient and adhere to the recommended curing times to ensure your gel mani remains intact and keeps that salon-quality glossy finish for up to two weeks or more.

Durability and Longevity


When choosing between Shellac and OPI gel color for your manicure, you’re likely concerned with how long your polish will stay pristine. Both products are known for their durability, but they react differently to wear and tear.

Wear and Tear Factors

Your daily activities play a significant role in the longevity of your nail polish. Shellac boasts a unique formula that’s thinner than traditional gels, potentially conforming to the natural movement of your nails better and thus, can be less prone to chipping. On the other hand, OPI Gel Color is known for its strength and the ability to remain long-lasting, even when faced with rigorous tasks.

Chipping and Peeling

Chipping and peeling are the bane of any manicure. Shellac is often celebrated for its chip-resistant finish which typically lasts up to 14 days. OPI’s gel colors, while thicker in consistency, also offer a chip-resistant armor for your nails, safeguarding against peeling and extending the life of your manicure. How you use your hands will ultimately determine which product offers the best wear and tear protection for your lifestyle.

Health and Safety Considerations

When choosing between Shellac and OPI Gel Color for your manicure, it is crucial to consider the impact on your nail health and assess the potential risks associated with the ingredients and removal processes.

Potential for Damage

The process of applying and removing gel-based polish like Shellac or OPI Gel Color can lead to nail damage if not done properly. Incorrect application or removal methods may result in breakage, brittleness, and the thinning of your natural nail. It’s important for you or your nail tech to follow the recommended procedures closely to minimize any adverse effects.

Nail Nourishment

Nourishing your nails is paramount to maintaining their health, especially when frequently using gel polishes. After removing Shellac or OPI Gel Color, apply cuticle oil to nurture the nail bed and nourish the surrounding skin. This can combat dryness caused by products like acetone, which is often used during the polish removal process.

Toxic Ingredients

Safety concerns regarding nail polish often center on toxic ingredients such as formaldehyde, toluene, and dibutyl phthalate. Both Shellac and OPI have made strides to remove these harmful substances from their formulas. However, always double-check the ingredients list or ask your nail tech to confirm the absence of these toxic chemicals to ensure the safety of the manicure product you are using.

Economic Aspects

When considering a gel manicure, you’re likely to evaluate both the immediate price tag and the long-term value. Below, explore how Shellac and OPI Gel Color weigh in economically.

Initial and Long-Term Costs

Shellac typically has a lower initial cost for both salon services and DIY kits. However, the value extends beyond the shelf price. In the realm of professional quality, Shellac is known for its swift cure time under an LED lamp, which can also mean less time spent in the salon and potentially fewer appointments. But, quality and longevity play crucial roles too. If your Shellac manicure lasts without chipping or peeling, you’re getting a good deal.

Moving on to OPI Gel Color, you may notice a slightly higher price point for their products and salon services. But with OPI, you’re investing in a brand known for its extensive range of over 140 colors and the promise of a durable finish. Pitted against the cost, this brings its own version of value, particularly if variety is a priority for you or if your OPI manicure stands the test of time with minimal touch-ups.

On the DIY front, while initially costing more, the at-home OPI kits might save you salon visits, thus distributing the cost over time and increasing its overall worth. Similarly, for professionals, the clients’ satisfaction with a long-lasting, vibrant finish could translate into repeat business and higher value for their services.

Remember, personal preferences for brand, quality, and color options will steer your decision, but understanding these economic aspects will guide you towards an informed choice that balances cost and value.

Removal and Aftercare


When it comes to removing Shellac or OPI GelColor, it’s crucial to follow the right techniques to maintain nail health. Aftercare is equally essential as it helps restore moisture and strength to your nails post-removal.

Proper Removal Techniques

To remove your Shellac or OPI GelColor, the removal process should start with gentle buffing of the nail surface to break the seal of the topcoat. Then, you’ll need to soak a cotton ball in acetone and place it directly on the nail. Secure the cotton ball with aluminum foil to ensure it stays in place and effectively breaks down the gel polish. After ten minutes or as directed by the product, use a cuticle stick to gently push the polish off your nails. It’s essential to be gentle and patient during this process to avoid damaging the nail bed.

  • Buff the surface of your nails.
  • Soak a cotton ball in acetone and apply to each nail.
  • Wrap nails with aluminum foil.
  • Wait and check after ten minutes.
  • Gently push the polish off with a cuticle stick.

Post-Removal Care

Post-removal care focuses on hydrating your nails and surrounding skin. Immediately after the removal process, wash your hands to remove any acetone residue, which can be drying. Next, apply a cuticle oil to reintroduce moisture and aid in healing any irritation caused by the removal process. Regularly moisturizing your hands and nails with nourishing oils or creams is among the essentials to maintain nail health after removing any gel polish.

  • Rinse hands to clean off acetone.
  • Apply cuticle oil generously to nails and cuticles.
  • Moisturize with hand cream regularly.

Aesthetic and Practical Choices


When you’re deciding between Shellac and OPI Gel Color, it’s not just about longevity but also the aesthetic appeal and the practicality they offer for both personal pampering and professional services.

Color and Finish Selection

Shellac boasts a collection known for its glossy finish and vibrant color, making your nails stand out with a polished look. It’s perfect when you desire that extra sheen and a fun pop of color. On the other hand, OPI Gel Color offers over 140 beautiful shades, enabling a more extensive palette to match your mood or outfit. Whether you’re aiming for that sexy red for a night out or a subtle pink for a relax day, OPI’s range provides you the creative freedom to express yourself.

Personal and Professional Use

Professionals often prefer products that balance ease of use with exceptional client results. Shellac’s speedy curing process under LED lamps can be a significant time-saver during manicures and pedicures. This swift application could make Shellac a go-to for salons aiming to increase efficiency without compromising on quality. For your personal use at home, consider the accessibility of the product, the equipment needed, and your skill level. OPI’s application may be more involved, but it allows for a customized approach to layering colors and achieving the precise level of opacity you prefer.

Whether you’re in a salon or at home, your choice between Shellac and OPI Gel Color affects the outcome of your manicure and pedicure experience, from the vibrancy of the hue to the practicality of the application process.
