Nail-Aid Sapphire Strength Mega Growth – Extra-Strength Nail Hardener with Sapphire & Zinc – Strengthens Thin Weak Nails for Longer Harder Growth – Ultra-Shiny Breakproof Finish

Very good! Lasts a while for wear, works great and strengthening the nail, growth, and keeping flimsy nails hard. Would recommend this brand to anyone.

Two years ago, I was struggling with my nutrition and my nails used to break and crumble as soon as they grew at all, it got to the point where it wasnt just embarrassing, it was painful. Pics attached were taken literally ONE MONTH APART when I first started using Nail-Aid. I haven't had any issues with my nails since. I LOVE Nail-Aid, I have recommended it to countless friends over the years. It works better than any other product at half the price. If I break a nail from being clumsy, I just file the sharp edge and put some Nail-Aid on that nail— it grows back so quickly! If you're considering it, please, please try it! I wish I had known about it sooner!!

I cannot go to the nail salon anymore because I have had Lupus for 40 years. Unfortunately just the dipping back and forth from nail bottles or using not cleaned properly nail utensils can pass germs. At my stage I have zero immune system so I protect myself. I have learned to do any type of nail I want but sometimes when I am ill my nails break. This is the only product I use to help build them back up during a flare. It works. I have people ask me who does my nails and I am proud to say “me”. This is one of the key players to healthy nails when your entire immune system is attacking you. It brings my nails back hard and as long as I prefer them. There are tons of thes products on the market and I wasted my money on over half but this is the gold ribbon winner. I will sometimes even use it over a coat of gel to put that extra strength if I feel I need it. Excellent product.

I started with the 3 day growth treatment and when that ran dry I found this one I wanted to try too. Between the 2 I can definitely tell the difference in my nails. There are 2 nails that for some reason are just still kind of flimsy but they are definitely not breaking as much as they used to! I type for living and have for the past 20 years so my nails take a beating, I never manage to grow them as long as I like because they constantly chip, peel and break soooo easily. I've still had a couple break, currently trying to regrow one that cracked really low and so far so good. It's nice to find a company that actually works because I have tried the more expensive brands for YEARS.

Ok, i am officially a believer! I don't even know where to start with this review. I've been taking all forms of collagen for a while and my nails would still be weak and break. But, Holy cow not anymore. The picture you see is a growth of 2 weeks. They are growing nicely, strong and healthy. And you might say: "But Dei, 2 weeks? That's not a lot" oh trust me, for me it is! The polish consistency is not thick like others. It dries super fast and it doesn't have a strong scent. Which I appreciate. I honestly just have one coat and it looks nice and shiny. I guess you could do more if you want, I didn't see the need. I've done a LOT over the past 2 weeks. Including gardening and as you can see the polish is intact. Im still impressed over that. Others would've started to peel or something... not this one. It looks like this bottle is going to last awhile. And is not even expensive. 100 recommend!

This peels off way too easy; but I'm always washing or cleaning, so it might last longer for others. I probably won't purchase again.

This stuff is amazing!! It helps strengthen my nails!! It gives a beautiful shine with or without nail polish. It helps my manicure last a really long time. Also prevented chips in your nails!!

Run don’t walk to these. Must-have for natural nail.

Way is my thing

ABSOLUTELY BRILLIANT PRODUCT fixed my flaky peeling nails. Menopause nails, awful dry, couldn't grow them. Tried this and now my nails are strong and long! I am so glad I got this product. It fixed them fast too! I wish I had before pictures to show. Even the two nails that never grow have grown! Also the vertical ridges I had that were getting deeper appear to have resolved.

Das ist wirklich echt...perfekt nagel

I wanted to love this product but found myself removing and reapplying every day as they would peel off! and having to use nail polish remover everyday to take them off isn't ideal as my nails are brittle which defeats the whole point of buying this products

Questo trattamento per unghie di stelle ne ha 50!!!! Ho sempre utilizzato prodotti come Mavala e Trind. Superati!!!!
