    (COSMO) - Ever found yourself on the verge of a meltdown because your nails are just so damaged they won’t even accept a basic manicure? Trust me, I get it. From years of getting acrylics to genetics working against me, I feel like I’m stuck with nails that are brittle, weak, and constantly breaking.

    Luckily, there are more than enough products to help us reinvigorate and rejuvenate our hair to its full potential. But how do you choose which products to try? How do you know which will work and which won’t? That’s where we come in!

    Hair Growth Serums are concentrated oils filled with nutrients and peptides to help condition and activate hair growth. Of course, every formula is different and some serums work a lot better than others.

    We’ve tested dozens of nail serums to determine our TOP FIVE choices, comparing effectiveness, safety, and price to make sure you find the nail serum that’s right for you.

    Let’s get started!

    1. OVERALL VALUE: LIAISON UltraGrow Nail Serum

    Effectiveness: 95%

    Safety: 100%

    Price: $

    Overall: A+

    This is by far our favorite choice when it comes to a simple nail growth serum that can revive growth in short nails, repair damage, and restore healthier nails. Liaison’s UltraGrow Nail Serum uses a powerful KeratinFuse Complex™ specifically focused on infusing each cell layer with strengthening keratin proteins and a blend of Cottonseed Oil and Olive Oil to nourish your nails, conditioning them to resist the daily wear and tear that causes chips and breaks. The majority of our reviewers raved about how hydrating the formula was, and everyone saw fast nail growth within a week. We also loved the pleasant scent it has compared to others that smell like strong chemicals. Best of all, it was the only product on our list offering a secret 50% discount link, making it one of the most affordable and valuable options in the market.

    By far, Liaison UltraGrow Nail Serum is the safest and most effective for reviving damaged nails and doubling nail growth. 


    Effectiveness: 90%

    Safety: 85%

    Price: $$

    Overall: A

    This treatment is infused with allantoin to improve rough, dull nails plus glycerin and aloe to add luster and softness. A lot of our reviewers shared how this helped their nails feel soft and hydrated. But it didn’t really help much with strengthening and lengthening, despite their 7-day claims. Overall, it’s a pretty affordable option if you just want some moisture on your nails.


    Effectiveness: 85%

    Safety: 80%

    Price: $$

    Overall: B

    If your issue is mostly your toenails, this is a great option. The formula helps fight bacteria and fungal infections so your toenails stay healthier. That said, we didn’t really notice anything else. We’re not too sure if it takes longer to see effects in terms of stronger and longer nails. And for its price, we’ve all agreed it might not be worth repurchasing. However, if you have problematic toenails, then this is your bet.


    Effectiveness: 80%

    Safety: 90%

    Price: $$

    Overall: B

    This one is also marketed towards toenails, but we also gave it a try on our hands. It’s got a great formula plus it’s vegan. This one focuses more on repairing damaged nails and restoring their appearance. We did notice an improvement but it took longer compared to Liaison’s quick results. Overall, still worth trying.


    Effectiveness: 80%

    Safety: 80%

    Price: $

    Overall: B

    This cuticle oil has some notable good ingredients, including jojoba oil and grape seed oil. Most of our reviewers commented how it did help nourish their nails, but not as quickly as Liaison did. A few of them also shared how it peels off from the nail, so maybe that’s one of the reasons why it takes longer to see the effects of the formula. Either way, if you’re looking to test out cuticle oils at an affordable price, this could be worth checking out.

    Why We Chose Liaison UltraGrow Nail Serum

    While we believe that we recommended some great nail serums and treatments, Liaison’s product was the top choice. We wanted to talk further with our investigative reporter Stephanie Marianne who helped finalize our list and how Liaison’s UltraGrow Nail Serum worked for her.

    Stephanie tells the story. 

    Personally, I never believed in the effectiveness of at-home nail care or treatments. I’d usually go to my local salon to get my nails done if I wanted my hands to look pretty for a special event. I wash my hands frequently, do the dishes, and take long baths so I never bother applying any treatment knowing I’m just going to get them wet and waste the product. So, I avoided products like these at all costs.

    But then my best friend, who I trust with my life, swore by Liaison’s UltraGrow Nail Serum. She said it was the fastest and most effective nail serum she’s tried. I, of course, didn’t believe her. But then she showed me her nails now and pictures of her nails from just around a week ago.

    I swear to you, my jaw was on the floor. I was screaming. In less than two weeks, her cracked and splitting nails were gone! I couldn’t stop inspecting her nails closely because they looked so good. I begged her to let me borrow her bottle, but instead, she gave me a secret 50% discount link. So I ordered my own immediately.

    I received my package two days later and prepared for my first nail pampering session. Following the instructions carefully, I washed my hands and dried them thoroughly. I applied a thin layer of UltraGrow Nail Serum directly to my nails and cuticles, focusing on areas prone to dryness or damage. I allowed the oil to absorb and felt my fingertips and nails feel softer and nourished than ever.

     How Does Liaison UltraGrow Nail Serum Work?

    I, Of course, was expecting immediate results, but it actually takes a little over a week to see real results. In the meantime, I started to do my research to find out how Liaison’s UltraGrow Nail Serum works and how it sets itself apart from other nail serums and treatments.

    A combination of strengthening keratin proteins and nourishing natural oils are infused in
    Liaison’s KeratinFuse Complex™ to restart growth for short or cracked nails, repair cuticle damage, and create a healthier nail bed that prevents chipping.

     Liaison’s Secret To Results… KeratinFuse Complex™

    The Nourisher
    KeratinFuse Complex™ begins its work by deeply nourishing your nails with Cottonseed and Olive Oils. These natural oils are absorbed into the nail bed, laying the groundwork for healthy growth and addressing brittleness and dryness, which are common in damaged nails.

    The Strengthener
    A potent mix of proteins works to strengthen the nail structure. This phase focuses on reinforcing the nail’s natural resilience, helping it withstand the rigors of daily life and reducing the likelihood of breakage and splitting.

    The Growth Enhancer
    In this final phase, Palmitoyl tripeptide-1, alongside Vitamin E, plays a crucial role in accelerating nail growth and improving cuticle health. This powerful combination ensures that not only do your nails grow faster but also healthier, longer, and more resistant to damage.

    Did It Finally Work?

    So, finally, in less than 2 weeks, I decided to check if I could see results… and wow! My dryness and chipping were gone, and my nails doubled in length and felt stronger! I was simply amazed at how great my nails look and feel.

     I’ve been converted into an UltraGrow Nail Serum believer, and hope you will, too.
