Two essentials with an extra boost of kur-infused care. Though this duo is great for all nail types, it’s especially transformative for those weak or soft, peeling nails. Get Strong Nail Hardener uses multi-polymer technology to create a shield-like barrier that immediately fortifies the nail plate and helps harden nails in as little as one week. Use alone, follow with polish, or finish with a layer of High Gloss Top Coat, our most cushiony formula yet for supreme shine.

Set includes full-sized bottles of:

Get Strong Nail Hardener: 

For best results use as a treatment: Apply 2 coats to bare nails every other day for the first 2 weeks. Get Strong Nail Hardener should be removed before applying a fresh coat of treatment. During week 3 and 4 apply 2 coats to bare nails every 4-5 days. Repeat process as needed. 

As a base coat: Apply one coat to clean nails and follow with your favorite lakur shade.

High Gloss Top Coat: Apply a thin, even layer over any lakur. For best results, apply top coat daily or re-apply at first signs of wear to extend the life of manicure or pedicure.

Get Strong Nail Hardener: Ethyl Acetate, Butyl Acetate, Alcohol Denat., Nitrocellulose, Acrylates/Hydroxyesters Acrylates Copolymer, Isopropyl Alcohol, Acetyl Tribuyl Citrate, Adipic Acid/ Neopenyl Glycol/ Trimellitic Anhydride Copolymer, Dipropylene Glycol Dibenzoate, Etocrylene, Brassica Campestris (Rapeseed) Seed Oil, Brassica Campestris Flower Extract, Chamomilla Recutita (Matricaria) Flowe Extract, Cucumis Sativus (Cucumber) Fruit Extract, Oenothera Biennis (Evening Primrose) Flower Extract, Carthamus Tinctorius (Safflower) Seed Oil, Tocopheryl Acetate (Vitamin E), Dimethicone, CI 42090, CI 60725

    Undecided

    I was excited to try the special nail hardener, but after trying it on two separate occasions I feel that it has a drying effect on my nails. After a couple days they start to flake and peel. I know you are supposed to remove the hardener and reapply every two days, but I feel like the nail concealers and nail veils leave my nails in better condition. I will continue to try it….maybe as a base coat next time.

    Thank you for your review and feedback, Genene. We regret to hear that our nail hardener formula did not meet your expectations and resulted in drying effects on your nails. This valuable insight allows us to further evaluate and refine the product to ensure an optimal experience for every client. We appreciate you highlighting this concern, as it contributes to our ongoing efforts to create high-quality, effective formulas.

    Your suggestion to try the hardener as a base coat is an excellent idea, as layering products can sometimes yield better results based on individual nail chemistry and needs. We're pleased to know that you've had positive experiences with our nail concealers and Perfecting Nail Veil polishes, which are designed to nourish and protect nails while providing a long-lasting, flawless finish.

    Please feel free to reach out to our customer service team if you have any other feedback or concerns. Your insights are invaluable as we strive to continually enhance our offerings and deliver an exceptional experience with every product.

    Great Product

    I loved the nail strength & duo shine. I'm in love with Londontown. Makes the best products for my nails. I've used a lot of other brands but nothing is as good as Londontown.
