I purchased this at the Dollarama (Canada) for $3. I heard its pretty expensive at drugstore so I bought a few. Overall I like it, it works well as a top coat and my polish actually stays on for a few days. A few days is actually huge for me cause no matter the top coat my polish always chips. Nails do feel stronger I can't say wether or not they feel moisturized but overall they seem ok. Some people commented that it takes to long to dry, I find if you apply shortly after applying your polish it does take awhile to dry. What I do with this stuff is ill apply my polish then wait a good long while sometimes even a day then I put this on. By doing this I actually find it dries almost immediately. I have no patience for waiting for my nails to dry lol
Oh and this product can cause air bubbles. So be careful with your application :) xo

Ending up getting this as they did not have the one I was looking for (OPI nail strengthener, yes I should have definitely waited to order online) I picked this one specifically out of Sally Hansens nail strengtheners because it had natural ingredients. It does harden the nail "slightly" not a significant difference maybe 10%, and is good for a base coat, haven't noticed a moisturizing, doesn't make my nails worse. For the price (I paid $17) it was not worth it. I'd say it would be worth about 5 dollars... will not be repurchasing or recommending.

UPDATE: Ending up worse than what I originally wrote. FIRST it peels like almost instantly, and when it doesn't peel off if you put nail polish on it and shower (doesn't matter if it's the next day) the bottom of the polish will start to fold up.. kinda like the water will melt the polish, even one coat. Trust me I've tried everything to make this product work as I've paid an outrageous amount of money for such a horrible product. It really is awful DON'T WASTE YOUR MONEY!!

I like to use this alone after I have cut/filed/buffed my nails. I totally heals dry cracked unhealthy nails. I helps my nails grow longer. It's very shiny and makes nails look shiny and healthy and pretty. I really love it. I've used it as a base coat/top coat but I don't like to. Base coats and top coats are completely different. it's like shampoo and conditioner in one. You don't get the full effect and the end result isn't as shiny.

I am always surprised when a product works. And I found that this one works for me. My nails have never looked better, shiny and healthy. My nail ridges are less noticeable. I would definitely buy this product again.

This cost $10 which is more than I would pay for nail polish, but I'm so glad I did. I can see noticeable growth after only a few weeks and as a top coat it makes my polish last twice as long. HG nail product for me!

Really dislike this because it is so hard to dry! I might spread my manicure out over several hours to ensure that everything goes on perfectly. But even hours and hours after using this product, I get crease marks on my polish! Grrrrr.

This product seems great the first day but it started to chip and peel off by the second. Also, I have been using it for about two months because I paid for it so why not use it. My nails look worse than when I started! They now chip more easily and one of my nails split in half horizontally; so the top half of one of my nails is gone and the bottom half is really soft, not shiny at all, and rough.
I was shocked at first, Salley Hansen has always been amazing and this got good reviews too. Also, my nails weren't bad before, I just wanted to be able to grow them longer. Now my nails are disgusting and I have to be really careful with them.

It is a good product, however I did find that it did not apply very smoothly, maybe because of the brush and also that with 9 months the product began drying up in the bottle. I expected better from a product that cost me NZD35 after all my OPI nail polishes don't dry out that quick and I pay NZD25 for them. I prefer Orly Base and Top coats now.

I have dry nails so that's why I decided to pick this one up. Sometimes I wear it alone or use it as a base coat. My nails look healthy and conditioned when I wear this product. I also like the shine. I would purchase again.

I've always been a Sally Hansen fan on nail products and I always will be. I bought this treatment as a first step for better and more moisturized nails. This treatment definitely satisfies me and my nails as a base coat and top coat. However, when worn alone with even 3 coats, it wears off really fast. I really wished it lasted longer or else it would have been perfect but I think I'll move on to other ones for now.
