Overdone the gel manicures or struggling with weak, brittle nails? We ask the experts how to repair nail damage at home.
You know your nails are really damaged when your own nail technician tells you that you need to take a break from your extensions. That’s how thin, weak and prone to breakage my nails had become. Even as a beauty director, I panicked about what I was doing to do. Long statement nails always made me feel put together, giving me the strength to face whatever work and social plans might throw at me. ‘Going bare’ with my nails sounded virtually impossible.
Then I got talking to some leading nail experts, and I realised that I’m definitely not alone. Reportedly, over one in five women have weakened, soft and brittle nails. Luckily though, and even more importantly, the nail industry is focusing on solutions to help us change that like never before.
In fact, the trend for bare, healthy nails has been growing for some time, with treatment-focused products helping fuel growth in the global nail care market, which is forecasted to be worth $36 billion by 2036. Nail strengtheners are the fastest growing category in nail care too, as consumers shift away from gels and towards a treatment-first approach to healthy nails.
“2026 is shaping up to be the year of short, healthy nails,” reveals the in-house nail expert for Mavala, Lynn Mason. “Consumers are moving away from gels and acrylics and gravitating toward products that support natural nail strength and growth. With this wellness-focused shift, shorter lengths will rise in popularity, offering a look that’s classic, refined, and effortlessly elegant”.
But while natural-looking nails might be right on trend at the moment, ‘healthy nails’ are what we should all actually be aiming for, according to all the experts I spoke to. Here’s how to know what might be causing your dry, brittle nails, and our favourite products for repair your nails at home, while you take a break from the nail salon.
What are the key signs of nail damage?
“You’ll often see nail damage before you feel it,” reveals the celebrity manicurist Julia Diogo, who is known as @paintedbyjools. “Nails can look visibly thinner and feel more flexible or bendy than usual. Peeling, splitting, ridges, or a rough, uneven surface are all signs something isn’t quite right. Sensitivity is another giveaway – healthy nails should never feel sore, especially during filing or removal”.
What causes nail damage?
According to research by leading nail brand Kure Bazaar, there are three main reasons nails can lose their strength and shine – and not all of them are your fault (you’ll be glad to know!).
1. Manual damage
Let’s start with the obvious culprits: daily life and what you put your hands through. In particular, if you love gels, acrylics and constant polish changes you’re definitely putting a strain on your nails, particularly if you tend to pick your gels off at home, or go somewhere that uses electric tools that can quickly overbuff your nails. But it isn’t just overdoing your trips to the nail bar. Overzealous handwashing and harsh cleaning products can also strip nails of natural moisture, leaving them soft and prone to breakage. Even cold, dry weather or long sun exposure can make nails brittle, ridged, or flaky – so frequent flyers can become victims of weak nails quite quickly.
2. Ageing and hormonal changes
But it’s not just our habits. You probably wouldn’t think too much about it, but ageing and hormonal shifts have a huge impact too. In fact, our nails are affected in a very similar way to our skin and hair as we age. As Ami Streets, expert manicurist, says: “as oestrogen levels fall, the body produces less natural oil (affecting skin, hair & the nail bed), which can leave nails dry and prone to breakage, peeling or flaking. Circulation and cell turnover slow down with age too, meaning your nails may take longer to grow as well as heal from any damage. Nutrient absorption may decrease as well, leading to thinner nails and the appearance of vertical ridges. Additionally, nails and surrounding skin may become more sensitive to products like acetone, adhesives or gels, which previously caused no issues but may now trigger irritation.”
3. Underlying health and nutrition
Stress also has a bigger role than you might think – especially if it leads you to bite or pick at your nails:
“Picking at your cuticles causes more damage than you might realise,” explains Diogo. “It disrupts the nail bed, and over time can lead to ridging, splitting and a weakened nail plate [even if you haven’t directly thinned the nail itself]. This picking is especially tempting during the cold weather in winter, when cuticles are naturally drier, which is why I always recommend applying a nourishing cuticle oil daily to remove the temptation”. Bio Sculpture’s Ethos Golden Nail Serum is an expert favourite.
Sometimes nails are a signal of more significant health issues too. Chemotherapy, certain medications, or nutritional deficiencies – like low iron, biotin, or protein – can leave nails weak and easily broken. Trauma, habitual biting, or aggressive filing will make the problem worse, making already fragile nails even more vulnerable. Paying attention to diet, lifestyle, and gentle care can make a huge difference, helping nails not just survive, but actually grow stronger over time.
So, what’s the solution?
If you start to see signs of nail damage, the first step is to pause and acknowledge it (however much you might not want to!). Giving your nails a little break from more aggressive treatments, such as extensions, or constant redoing of polishes can help, but it’s also worth giving your nails a pamper too – as you might do with sensitised skin to get it back on track. It also turns your nail rehab into a comforting wellness ritual.
“I love a targeted treatment that supports my nail, rather than just masking the damage,” reveals Diogo. “I would focus on gentle, strengthening care that builds the nail back up through nourishing ingredients”.
With that in mind, here are some of our top picks for treating nail damage…
The best products for nail rehab
This nail treatment is designed specifically for those moments when your nails need a rest but you still want them to look glossy and well-cared-for. It is formulated with natural bamboo extract (which is rich in silica), helping strengthen weakened nails, while also conditioning and smoothing out signs of damage, like uneven ridges. In just a week, user trials shown visibly stronger nails too.
Staying true to Leighton Denny’s ‘skincare for nails’ philosophy, this 2-in-1 treatment polish elevates your nude nails so you feel less tempted to rush back to gel manicures. The formula is enriched with botanical extracts that revitalise dull and discoloured nails, and the soft lilac shade can be worn alone or act as a brightening base coat – whatever you prefer.
If you have a tendency to pick at your bare nails, especially dry cuticles, you'll know first-hand that it can lead to even more issues, including red, sore skin that makes your nails look less polished. Lightweight and fast-absorbing, this Navy serum nourishes dry, flaky cuticles without greasiness, and a little goes a long way, courtesy of a hydrating blend of plant collagen and grape seed, castor, and argan oils.
This small but mighty nail hardener is a must-have in any at-home manicure kit, but especially for anyone struggling to grow their natural nails after a few too many harsh manicures. Designed as a twice weekly treatment, it helps reinforce nail strength at all three layers of the nail bed, preventing flaking so your weak, brittle nails can actually heal.
OPI's clever nail strengthener doesn't just slap the equivalent of a plaster on weak, flaky nails, it helps heal them from within. That's courtesy of the brand's patented Ulti‑Plex Technology, which penetrates the nail surface to build and repair keratin bonds from the inside out. That helps smooth ridges and make your nails more resistant to breakage in just six days. Plus, it doubles as a prep under polish thanks to its zero‑dry‑time formula.
Who says caring for your nails has to mean breaking up with colour too? Kure Bazaar’s new nail therapy collection proves you can embrace both. At the heart of the range is the first-ever colour repairing nail serum, blending skincare actives with a polish-like finish, so your nails get stronger, healthier, and visibly radiant while you enjoy your favourite shades.
Bio Sculpture is a brand loved by many nail experts, including Julia Diogo, who always reaches for the brand's bases to strengthen her nails and those of her clients. In fact, she sees the products as part of her skincare routine. The Vitamin Dose is a particular go-to because the keratin-booster works just as well on gels as it does on bare nails, which makes it so easy to use, while keeping your nails strong and healthy.
Finally, do I really have to break up with gel manicures for good?
The short answer – with a sigh of relief – is no.
“It really comes down to the right systems and the right professional,” explains Diogo. “Choosing nail-friendly products, avoiding aggressive prep and working with a well-trained nail tech who genuinely prioritises nail health makes all the difference. With proper training, good brands such as Bio Sculpture that work with your nail type – whether that be strong, flexible or normal – and the right prep, your nails can stay strong, healthy, and resilient, even with enhancements”.
But, you should break up with your bad habits about removing your gels, of course.
