Nail Magic Nail Hargener

Works Like Magic

If you've already tried numerous strengthening products but none of them has worked for you, it's time to switch to something more serious and professional like the Nail Magic Nail 2-in-1 solution. It really works miracles and can repair even extremely split and broken nails relatively quickly.

As the name suggests, this nail product can bring a double benefit to your nails. Not only does it make your nails harder but also it deeply conditions them to bring back their beauty. Made with a unique blend of ingredients, it enriches your nails with a generous amount of nutrients, making them grow healthy and shiny. And owing to the addition of the castor oil, the product creates a protective barrier for that nourishment. That is to say, it shields nails from negative environmental effects. Castor oil is also known for its anti-viral, anti-fungal, and anti-bacterial properties. Hence, you can have peace of mind knowing that no fungi or bacteria will lurk in your weak nails.

This powerful nail conditioner should be used once a week after the initial treatment. It goes on well and gives a slight sheen to the nails. It can act as a standalone treatment as well as a base coat or a top coat.

In all, if you have terribly flakey nails and want to grow them strong and healthy, we would recommend going with the Nail Magic Nail. It works its magic where others fail.

OPI Nail Envy

Make Them Envy Your Nails

If you'd like to repair your nails after long years of wearing gel nail polish, the OPI Nail Envy Treatment can come to your rescue. It's a super-powerful treatment that can help restore even extremely weak and damaged nails in a short while.

Formulated with hydrolyzed wheat protein and calcium, this nail strengthening product provides the maximum hardness to your nails. When it comes to maintaining the strength and structure of nails, these ingredients are known to be the best at keeping the tissues of the nail bed healthy. So, they will help you grow strong and long nails that will be less prone to dryness. And what is notable, after the very first use, you'll notice an immediate improvement.

This bombproof miracle polish can be used as a standalone treatment or as a base coat. We would like to stress that this strengthener is available in various colours, unlike many other similar products. To specify, you can get such nude shades as Samoan Sand, Hawaiian Orchid, and Bubble Bath. Though the polish is almost sheer with one coat, two or three coats do the trick.

To conclude, if you'd like to treat your nails while masking the damage and small imperfections, the OPI Nail Envy Treatment is the best solution. It'll breathe new life into your weak, damaged and cracked nails in the most beautiful way.

Renunail Dr Lewinn's Private Formula

For French Manicure

Would you like to grow those perfect French-style nails? If so, the Dr Lewinn's Private Renunail Nail Strengthener can help you with that. It's fortified with calcium gel to put an end to splitting and peeling nails.

The strength of the Renunail hardener is that, in addition to effectively reducing flaking, chipping as well as splitting of nails, it also acts as a protective barrier against detrimental environmental effects, shielding the nail plate from dehydration and cracking caused by the use of harsh detergents and soapy water. As a result, with regular use (around 4 weeks approximately), you should be able to improve the health of your nails and encourage their growth.

What's also good is that you can wear it together with your regular nail varnish. Just paint it as a base coat and then apply your favourite polish. For better results, it's recommended to apply the nail-care Renunail treatment over the polish as a top coat as well, and repeat this procedure every five days.

If you stay consistent, your nails will look and feel as tough as French nail acrylics. And to make your nails even smarter, you can additionally use a white nail pencil to brighten the tips.

The only negative of this nail hardener is that it contains Formaldehyde. This might be an offsetting factor for those who are sensitive to this compound. That said, seeing that Formaldehyde's used in a ton of cosmetics, we are not holding it against this product.

In all, if you need a superior nail-care treatment and don't mind a little Formaldehyde in its composition, this product is for you. It'll make your natural nails much stronger and more glamorous with ease.

Mavala Scientifique K Plus

Acts on the Natural Keratinization of Your Nail Plate

If you're in search for an effective rebuilding and hardening serum that will quickly seal your nail plate and protect it against all kinds of damage, you should take a closer look at the Mavala Scientifique K Plus Nail Hardener. It's a perfect solution for soft nails that tend to split and break.

Infused with PRO Keratin, the serum works along with the nail keratinization process. It gets deep into the nail plate and makes it grow harder. In other words, it's a unique nail treatment that remarkably improves the adherence of keratinized nail cells forming nail disks.

Like the majority of other similar products, the Mavala Scientifique K+ is not an instant nail hardener. It gradually enriches your nails with nutrients and makes them grow harder in a few weeks. For the best results, you should apply it to clean nails 2-3 times a week. Move the brush from the centre to end and avoid cuticles and skin around your nails. The serum soaks quickly into your nails, allowing you to put a polish on top. The bottle contains only 5 ml; however, a little goes a long way, so it will last you nearly a couple of months.

All things considered, the Mavala Scientifique K+ is a great nail care product that boosts natural keratinization process of your nails. It offers quick help for fragile tips and flaking nails.

Sally Hansen Good Kind Pure

Completely Natural

The Sally Hansen nail hardener is a real boon for all eco-conscious customers in the UK. It's completely safe, cruelty-free, and vegan.

With 100% vegan formulation, the hardener uses no animal-derived products and nasty chemicals such as acetone, phthalates, parabens and other nail toxic ingredients. It's plant-based and contains such naturally-derived ingredients as potato, wheat, corn, and sugar cane. Still, it's quite effective at toughening the nails up.

Just like the nail polish, the brush is produced from 100% plant based ingredients. To specify, the bristles are made of castor bean oil and can help you achieve a perfect application.

This hardener is a completely clear varnish that can be worn alone, as a base coat under a coloured polish, or as a top coat over it. It dries fairly quickly and leaves a nice shine on your nail that doesn’t go dull after a few days. Also, it doesn't chip even with lots of layers. However, we believe you'll need only one coat as it has quite a hard texture. For the same reason, it also significantly improves the appearance of ridges even when applied alone.

All in all, if you want to achieve radiant, healthy-looking nails in the most ecological way possible, this product is for you. This is a good natural hardener that will appeal to most people searching for ethical beauty products.

What Is a Nail Strenghtener?

Unfortunately, as a study led by researchers at Harvard Medical School reveals, 27% of women have brittle, weak nails (also known as onychoschizia). This can be caused by some health conditions or external factors. So, if you do a lot of gardening, decorating, washing, and other housework, more likely than not, your nails need rescue. And a good nail strengthener can fit that bill perfectly.

A nail hardener is actually a clear polish that brings a double benefit to your nails - it leaves them glossier and stronger. This type of treatment makes fragile nails much tougher and tackles such issues as splitting, peeling, and chipping. It also hides small imperfections and deeply hydrates your nails.

A nail hardener treatment is usually enriched with proteins or keratins to encourage healthy nail growth. These elements react with the natural protein found in your nails, thus creating stronger chemical bonds. With that, nail strengtheners don't require a lamp to "set" in. They come with a brush in the cap and can be applied quickly and easily. Depending on your needs, you can use a nail hardener as a top coat, base, or a standalone product.

To enhance the effect of a nail strengthener, we recommend you to use it in combination with cuticle oils. These can deeply moisturise not only your cuticles but nails as well. And since hydration is the key, you'll be able to grow healthy nails quicker.
