July Pro Tips: Five Essential Nail Strengthening Tips

Healthy, naturally strong nails are in demand. And as a nail professional, helping your clients achieve this through targeted product recommendations and home-care tips can benefit the longevity of your own services, too.

In this month's Pro Tips guide, we'll explore five nail-strengthening strategies to give your clients nails to be proud of, whether manicured or au natural. Read on for some of the best nail care products to retail and recommend!

What weakens your clients’ nails?

To help your clients achieve super-strong nails, the key is to understand what’s causing them problems in the first place. From painful breakages to peeling, weak nails can be a major source of frustration in their beauty routine, not to mention in the quality and longevity of your own fair work.

Since we use our nails every day, routine tasks and habits can have a surprising impact on their health, even in ways your clients aren’t aware of. For example:

“One thing many clients don’t realise is that keeping your nails wet for long periods can actually weaken them,” says Sandra Andrews, Glitterbels Education Ambassador. “Repeated exposure to water can cause the nail to absorb moisture, swell, and then shrink as it dries. Over time, this can lead to peeling, splitting, and breakage, making clients think their nails are naturally weak when it’s often down to environmental factors and daily habits.”

Some of the most common causes of weak, brittle or damaged nails include:

Cause	Impact on nail health
Excessive water and chemical exposure	Regular contact with water, cleaning products and harsh chemicals can weaken the nail’s structure over time.
Poor removal practices	Picking, peeling or aggressive filing removes layers of the natural nail plate, leading to thinning and weakness.
Over-filing and excessive buffing	Removing too much of the nail surface during prep weakens the nail’s integrity and increases sensitivity.
Dehydration	Dry nails are often more prone to splitting, peeling and breakage.
Nail trauma	Using nails as tools, suffering repeated knocks, and everyday wear and tear can all contribute to cracking and breakage.

Hard vs strong: a key difference!

One of the biggest misconceptions your clients might have about nail strength is that stronger nails simply mean harder nails. The reality is quite different!

Healthy nails need a balance of strength, hardness and flexibility. Nails that become overly dry or brittle may actually be more likely to crack and split, which is why effective nail strengthening focuses on overall nail health, toughness and wear-resistance, rather than creating an excessively hard nail plate.

Why are strong nails important for pros?

The benefits of good nail habits go beyond nail strength itself. According to our nail pros, strong, healthy nails are a win for both you and your client:

“Promoting good nail health allows nail professionals to deliver consistently higher-quality services and achieve better long-term results for their clients,” says . “When clients understand how to care for their nails, we see improved retention, fewer unexpected breaks and healthier natural nails at each appointment. It removes a lot of the guesswork and allows us to work from a stronger foundation every time.”

Sandra agrees, saying: “Healthy natural nails provide a stronger foundation for any nail service, leading to better retention, fewer breakages and more consistent results. It also allows us to deliver safer, more effective treatments while helping clients achieve their long-term nail goals.”

The bottom line

By supporting your client’s nail health, you’ll not only find your clients are happier (which we all love to see!), but you’ll also find it:

Improves the longevity of your treatments by creating a stronger foundation for gel polish, builder gel and nail enhancements.
Promotes healthier-looking results with nails that are less prone to peeling and breakage.
Helps to build trust and credibility with your client base, positioning you as their go-to expert for all things nails.
Creates opportunities for maintenance services such as builder gel overlays and repair treatments.

5 pro tips for nail strengthening

The strongest nails come from a combination of home care habits and professional support. Here are five tips to pass on to your clients, to help them and, ultimately, help you!

Pro tip 1: have a damage repair ritual

The first step on a nail health journey is to address existing damage. For clients with peeling, thinning, or post-enhancement damage, start by offering a dedicated consultation and repair service to get them on the right track.

Products like OPI Repair Mode™ Bond Building Nail Serum are hugely popular for nail repair. The patented repair ingredients penetrate the nail surface to create new keratin bonds from the inside out, promising up to 4x stronger nails if used correctly. The treatment comes in a handy 9ml bottle, so it can also be retailed with the recommendation to apply twice a day for a minimum of six days.

Pro tip 2: make cuticle oil non-negotiable

If there's one habit that can make a significant difference to nail health, it's regular cuticle oil application. Clients may view cuticle oil as an optional add-on, but it should really be part of every nail care conversation.

“Cuticle oil is essential because it helps keep the nail plate hydrated and flexible rather than dry and brittle. Regular use supports healthy nail growth from the matrix and can help reduce peeling and breakage,” Sandra tells us.

As well as incorporating cuticle oils into every service, applied before soaking off or after polish and enhancements have been applied and cured, encourage your clients to add them into their own daily routine. Applying after handwashing is an especially effective approach to replenish and hydrate, and oils based on jojoba or almond oil, and rich in vitamin E, are best.

Pro Tip 3: Builder Gel or BIAB as a Protective Layer

When it comes to healthy nails, think protection as well as strengthening. Builder gel and BIAB overlays, from brands like The GelBottle, Glitterbels and The Manicure Company, are fantastic for offering an additional layer of support that helps reduce the risk of breakage and allows your clients’ natural nails to recover underneath.

Not only does builder gel offer plenty of options when it comes to embracing colour and nail trends, its thicker consistency also helps to absorb daily wear and tear while remaining flexible enough to move naturally with the nail bed.

The key is to position builder gel correctly: while it cannot “fix” the natural nail underneath, it can provide a protective structure while healthier growth comes through.

Pro tip 4: be gentle with nail prep

Good prep supports retention, while over-prep creates weakness.

The aim when preparing the natural nail is to remove surface shine and create the right foundation for product adhesion, not to thin the nail plate. Aggressive filing or excessive buffing can compromise the natural nail and contribute to sensitivity or peeling, as well as poor long-term results for your work.

Choose the correct grit for the task and work with controlled pressure, avoiding repeatedly filing the same area. If a client already has thin or damaged nails, adapt your prep rather than following a one-size-fits-all routine.

Pro tip 5: get nail removal right

Poor removal is one of the biggest causes of nail weakness. Discourage your clients from picking, peeling or scraping nail polish, which can lift layers from the natural plate and leave their nails thinner, rougher and more prone to breakage.

Explain that safe, professional removal protects their next set as much as their current one, and encourage them to return for proper infills or removals wherever possible. Using the right products and allowing sufficient soak-off time will help minimise unnecessary damage.

Amy Ball tells us: “I believe it’s my responsibility as a nail professional to educate clients on how to look after their natural nails between appointments.”

“I always take the time to explain simple aftercare advice, such as using cuticle oil regularly, avoiding picking or peeling products, and protecting their nails from unnecessary stress. When clients understand the “why” behind the advice, they’re much more likely to follow it.”

Bonus pro tip

We love this final additional tip from Education Ambassador Sandra: “A Keysie is the perfect companion because it helps prevent clients from using their nails as tools for everyday tasks like opening cans, parcels, or keyrings!”
