Types of Gel Manicures: 6 Options Explained Step by Step

There are six main types of gel manicures offered in salons today: soft gel, hard gel, BIAB (Builder in a Bottle), Shellac, Polygel, and structured gel. Each type uses different formulas, curing methods, and removal techniques - resulting in unique levels of strength, flexibility, and wear time. For example, soft gel offers a natural, polish-like finish with easy soak-off removal, while hard gel and Polygel allow for sculpted extensions and long-lasting durability. BIAB is ideal for strengthening weak nails, and Shellac provides a lightweight hybrid option. This step-by-step guide explains how each gel type is applied, who it suits best, and how to choose the right option for your nail health, lifestyle, and styling goals.

1. Soft Gel Manicures

Soft gel is the most popular entry-level option, ideal for natural-looking manicures that last up to two weeks.

Soft gel polish is applied much like traditional lacquer but cured under UV or LED light to set. It forms a flexible, glossy layer that resists chipping better than regular polish. Removal is done by soaking in acetone for 10–15 minutes, making it a convenient option for frequent updates.

Soft gel suits those who want a natural finish without committing to heavier overlays or extensions. It's lightweight, affordable, and widely offered in both salons and DIY kits.

2. Hard Gel Manicures

Hard gel is a stronger, more structured product used for overlays or extensions. Unlike soft gel, it cannot be soaked off with acetone and must be carefully filed down by a professional.

Application involves layering the gel over the natural nail or form, then curing with UV/LED light. Its hardened finish provides durability and shape retention - ideal for clients who need added length or reinforcement.

Hard gel is often selected for sculpted nail designs or for nails prone to breaking, especially in busy lifestyles or physical work environments.

3. BIAB (Builder in a Bottle)

BIAB - short for Builder in a Bottle - is a hybrid category between soft and hard gel. Originally developed by The GelBottle Inc., it provides strength while remaining soak-off compatible in many cases.

This product is brushed on like polish, but builds up enough density to strengthen the nail. It’s commonly used in nail rehab routines for clients recovering from damage or breakage.

BIAB is especially popular in Sydney nail salons for clients looking to grow their natural nails without extensions, offering a clean, structured finish.

4. Shellac Gel Manicures

Shellac is a brand-specific gel system created by CND that blends traditional polish with gel technology. It’s known for fast application and removal, making it ideal for those who want salon results with minimal time investment.

Applied in thin coats and cured under LED light, Shellac offers a high-gloss finish that resists chips for up to 14 days. Removal takes less than 10 minutes with acetone wraps, making it a great option for clients seeking both beauty and convenience.

Shellac manicure is perfect for short-term occasions or regular polish users who want more longevity without bulk.

5. Polygel Manicures

Polygel is a unique blend of acrylic and gel, offering a dense, sculptable formula that doesn’t harden until cured. It’s applied with a spatula, shaped with a brush, and set under LED/UV light.

Because of its thickness and strength, Polygel is widely used for nail extensions or structured overlays. Unlike hard gel, it provides flexibility, making it more forgiving during wear. Removal usually requires careful filing due to its solid nature.

This type is ideal for long-lasting nail art or clients needing custom shapes and maximum durability.

6. Structured Gel Manicures

Before jumping into the table, it’s important to clarify that "structured gel" is a method rather than a product type. It involves creating a stress-bearing arch (apex) using builder gel or BIAB to reinforce nail shape and prevent breakage.

Structured manicures focus on architecture - layering the gel in a way that corrects flat nails, supports growth, and enhances longevity. They are especially effective for clients with weak or peeling nails.

FAQs About Types of Gel Manicures

The many gel manicure options can be overwhelming. Below are detailed answers to the most frequently searched queries, based on actual Google query data and salon insights.

How long does a gel manicure last on average?

On average, gel manicures last 10 to 21 days, depending on the type of gel, nail prep, and aftercare. Soft gel and Shellac often last around two weeks with proper prep, while hard gel or BIAB can remain intact for up to three weeks or longer. Structured gels extend wear further due to their layered support. Avoiding hot water and using cuticle oil regularly can also extend the lifespan of any gel application.

Is gel polish damaging to natural nails?

Gel polish itself is not damaging when applied and removed correctly. However, improper removal - such as peeling or over-filing - can strip the nail plate and cause long-term weakness. Using structured gel methods like BIAB or builder gel can actually protect and improve nail integrity. It is essential that gel products be removed by professionals and not forcefully picked off at home.

What is the difference between a hard gel and a soft gel?

Hard gel and soft gel differ in flexibility and removal. Soft gel is soak-off and feels more flexible on the nail, mimicking traditional polish. Hard gel, in contrast, offers more structure and can be sculpted for length - but must be filed off. Hard gel is better for shaping and support, while soft gel suits casual wear and polish-like finishes.

What is a structured gel manicure?

A structured gel manicure is a layered application technique where builder gel or BIAB is used to create an arch (apex) for strength. This method reinforces weak nails, corrects flat nail beds, and improves durability by distributing stress across the nail plate. It's especially useful for clients recovering from nail damage or seeking longer-lasting manicures without extensions.

Are there non-toxic or allergy-safe gel options?

Yes, many gel systems now offer HEMA-free or low-acrylate formulas designed for sensitive clients. These products reduce the risk of allergic reactions, which are typically caused by prolonged exposure to acrylates found in traditional gels. Salons may carry brands that specialise in hypoallergenic formulas, and it’s best to request patch testing or ingredient lists prior to booking.
