This £9 Product Is My Secret to a Long-Lasting, Salon-Like Manicure at Home

One of my New Year's resolutions for 2026 is to save a bit of money. One way I plan to do that is to stop going to the salon every two weeks to try out Wholesale Replica Bag nail trends. I've been a gel manicure lover for years, mainly because it lasts significantly longer than regular nail polish. However, because of my new goal, I've started doing my nails at home, and I'm constantly searching for ways to make my manicure last longer and look a little more, well, professional.

After testing lots of products out, I've come to learn that a nail top coat is the simplest (and most affordable) way to make your at-home manicure look as good as possible, and keep it that way for as long as possible, too. Intrigued to know more? I spoke with nail expert and brand founder Leighton Denny MBE, all about how to get the most out of your top coat, and even included my edit of the best ones on the market. You're welcome.

What Is a Nail Top Coat?

"A nail top coat is the final seal for your manicure," explains Denny. "It’s a clear layer applied over your dry nail polish to create a protective coating. While the base coat helps polish adhere, the top coat acts as a shield for your nails. It generally provides superior gloss and a high-shine finish, enhancing the true colour of your polish."

Denny tells me that whilst top coats come in different finishes, choosing a quality formula can make all the difference. Ideally, you want something that will help to boost colour vibrancy and achieve a professional-looking finish.

How to Apply a Nail Top Coat

Once you've found your chosen top coat, application is key. "For best results, apply a thin coat and be sure to seal the tips by brushing right across the free edge. This caps the manicure and helps prevent chips," explains Denny.

I've been busy testing out the best top coats on the market.

Can a Top Coat Make Your Manicure Last Longer?

The big question is, can a top coat actually make your manicure last longer? According to Denny, it absolutely can. "It protects polish, keeps colour fresh and vibrant, prevents chipping, fading and yellowing, and it adds strength to fragile nails prone to breakage."

1. OPI Infinite Shine Top Coat

If you want a long-lasting manicure with a gel-like finish, this OPI top coat will be your new best friend. It features an innovative formula designed to mimic gel polish, creating a plumping effect, adding shine and protecting your manicure. I personally find it easy to apply thanks to the slightly wider brush, and it's so shiny that I also love wearing it on its own when I want that glass manicure look.

2. Leighton Denny Crystal Finish Quick Dry Top Coat

If you want a super shiny finish, I recommend this top coat from Leighton Denny. As the name suggests, it gives your nails a crystal-like effect, making them look as if you've just left the salon. It also creates a protective coating on the nail to lock your polish in and keep it looking fresh. Sometimes, I actually like to apply a thin coat of this a few days after doing my nails when they are looking a bit dull or lacklustre, as it immediately brings the colour back to life.

3. Dior Top Coat

For a touch of luxury, I like to reach for this top coat from Dior. Not only does it look super chic and feel like a treat when I'm having a break from the salon, but it's also really, really good. I've written all about my love for Dior nail polishes, but this top coat is the perfect finishing touch, setting my polish in place and adding beautiful shine.

4. Nails Inc. Better On Top Quick-Drying Top Coat

When I want something a bit more affordable, I reach for this top coat from Nails Inc. What I love about this formula is that it's enriched with a blend of blueberry extract and peptides to help nourish your nails and promote a stronger feel. My nails are feeling particularly weak at the moment, so I've been using this a lot while doing my mani at home. It's easy to apply, dries in under a minute and adds a glossy finish.

5. Chanel Le Vernis Le Gel Coat

First of all, how stunning does this top coat look? Chanel has really knocked it out of the park with this one. If you want a gel-like finish, this is a great choice, as the formula works to protect your polish and accentuate shine, thanks to film-forming agents and camellia eco-ceramides. Plus, the smaller brush makes it easy to get a salon-worthy finish.

6. 14 Day Mani Clear Hema-Free No-Wipe Top Coat

If you are doing gel nails at home, this is the top coat I swear by. In fact, I use the entire 14 Day Mani range for a salon-like experience straight from my living room. You will need the brand's gel polishes and UV lamp for this one, but trust me when I say that this top coat seals your polish in place, adds shine and makes your manicure last for two whole weeks.
