I have nails that chip and break very easily, but this not only resolves that issue, but it gives them a nice shine. I've been using it for years, usually after I take off my acrylics to help the nail bed strengthen and heal. Also doubles as a decent base coat.

This products is ok. I use it underneath nail polish. It hardens my nails while I'm wearing it, but I don't feel like it actually treats my nails and makes them stronger and harder on their own. It applies smoothly and dries very quickly.

This product literally DESTROYED my nails!  They needed some help, but after using this product for a month, my nails just about disintegrated at the tips!  I wish I could give it -5 Stars. Going back to the Nailtiques Formula.

This is my go to after removing acrylic nails. I have to take a break from acrylics from time to time and let my nails restore themselves. This treatment really helps prevent breaking and splitting.

If you're looking for something to keep your nails protected and strong, but don't want nail polish color, this is ideal. I don't find it works at all as a base coat... and it actually seems to make my nail polish peel away quicker in that capacity. However when I don't want my nails painted, but I'm still gardening and working with my hands a bunch, it gives a healthy shiny finish and the protection my weaker nails desperately need.

I wasn’t really sure if this would work on my nails to be honest. After having acrylics on for years my natural nails were really thin and brittle; I was constantly paranoid that I would really hurt my nails doing daily tasks. After using 2 coats of the hardener treatment 2x a week for the past 6 months, my nails are better than ever!!! Love love LOVE this product!

This has helped my nails so much! I already love my nails, but they tend to grow so quickly. They get thin and break easily because of this. Hard as nails is perfect for me because I dont always have a color on my nails; but this alone leaves them looking shiny, healthy, and polished. It keeps them healthy and prevents the nail from breaking. This is also a key step to any manicure in my opinion. A good buy from the drug store!

I have used this for probably 15 plus years. It definitely helps to strengthen nails and is great if you want to wear your nails natural but don't want them to break. It's not the best as a top or base coat if you're going to use it with polish, but on it's own, it's fabulous!

I always saw my grandma using this while I was growing up and then I started using it when I became a teenager. I love the natural tint that this gives your nails. This works really well at keeping your nails from splitting. This is a must have if you have naturally long nails!

My nails are very thin, brittle and just generally unhealthy. I tend to bite them as a result of this and am currently trying to grow them out. I want something that coats my nails like polish(not a rub in or oil type application). I was using another hard as nails product and it peeled off in full gel like pieces and chipped and peeled super easy. Will this protect my nails and help them grow without chipping and peeling?
