this nail thickener does not work for me. It takes a very long time to dry. Also the product claims that it can be used as a base coat, however, everytime i use it as a base coat the nail polish takes days to dry no matter how fast drying the nail polish is. So I will not continue using the product and will not buy it again.

Very disappointed in this product -ruined my nails

6 years ago
I have very strong nails, but though I'd use this to help my nails get stronger, and grow a bit more. What a mistake! This product ruined my nails within 3 days! Every single one of my finger nails either broke, or peeled. And my nails have never peeled before. So disappointed and this was a total waste of money - threw straight in the bin. Was rubbish.

Not worth the money

Just as other reviewers said, it bubbles (even without shaking) and doesn't even last a day! Wish I had read reviews first instead of wasting my hard earned money! Don't waste yours!

I used a few times following directions (not that hard) and the polish peels off the next day. Never using these products again!

    Nails still peeled

    7 years ago
    I bought this about three weeks ago and applied it to my nails following directions. It actually peeled off my nails and took some of my nails with it. I wanted to be sure so after 6 days I polished my nails. You can see the unevenness of the polish where the Miracle Cure peeled off on my finger tips. I don't know what to do next!

          This is a nail thickner and strengthener. Did neither. I didn't have any issues with air bubbles or flaking as other reviewers did, it just didnt do what its supposed to- thicken and strengthen my nails !

          Bubbles!

          8 years ago
          I have been using this product for 2 weeks, and agree with most other reviews. Not at all what it's cracked up to be. Dries with lots of bubbles and flakes easily. Have not noticed nails are thicker. It's very shiny but shows every single ride, bump and flaw. Come on Sally, what are we doing here?

          Bought the other day. Applied once, went about normal day and by the end of the day flaked off. Read the bottle, said to apply everyday. Well, I did and by the end of the day flaked off again. I guess that's why they say to apply everyday, because it is flakes off.

          dont bother gunk in a bottle

          9 years ago
          bought this two weeks ago and am sitting here crying used as per instructions, as my nails are thin I applied every day for four days, as it says then I tried to take it off OMG! my nails are ruined, Ive had to resort to 'picking' it off because using nail varnish, with or without acetone, just turns everything into a sticky gunky mess! What I managed to get off has made my nails look like theyve been sand blasted, all the top layer has been taken off, no shine at all. How Im going to get the rest off, god only knows. Will be popping into nail salon to ask if they can advise or sell me something to do so

          this is rubbish

          9 years ago
          i purchased this 3 weeks ago from Asda for £10.00 which I thought was expensive but I'd used other Sally Hansen products and had been happy with the results, therefore I thought this would do what it promised - NO it peels of within one day, I tried the four day applications but with it peeling off my nails are no better and I'm £10.00 out of pocket

          Hard to remove

          9 years ago
          A lot of air bubbles appeared like magic after the stuff dried.After a couple days it starts to crack and looks terrible, even applying more does not fix that look. It says to use nail polish remover to remove it, but the remover does not work very well. It is very hard to take off.

          Can't get it off!

          10 years ago
          I applied one coat and then a second coat the next day. The following day it started to crack a flake off. When I went to remove what was left I couldn't get it off - even after three attempts with nail polish remover. The best I could get is a gummy mess.

          My nails have become brittle in the last couple of years. I have tried a lot of products and have been disappointed, they never delivered what they promised . Well, they at least where useable. From the first time I took the brush out to paint a stringy sticky mess! Need to find out how to get guarentee .

            I bought this one after I tried Diamond Strenthth, Advanced Hard as Nails and Miracle Cure. It is as bad as Advanced Hard as Nails. It does not keep on. I used it on clean and dry nails, was very cerful but nothing helps: this polish flakes next day. I do not like it and in the future I will only buy Diamond Strenght for staying power or Miracle Cure for staying power and better shine.

              I know your not supposed to shake the nail thickener or it creates air bubbles ( first time using it I shook it and got lots of air bubbles) so the second time I used it 2 months later I didn't shake it at all, I put it on and there is STILL air bubbles covering my whole nail after it dried!

              12 years ago
              My nail problem is weak and flaky nails so I hoped this would protect my nails. It flakes off the tips almost straight away. Even applying another coat didn't stop it chipping away. Provided no strength or thickness at all.

              12 years ago
              I had high hopes for this product but have found it to be a total waste of money! It goes on nicely, but as soon as you put your hands in water (to wash them or even shower) it starts to chip and peel off. After a few days of applying it I gave up as my nails looked horrible and I feel they are softer and more damaged than before I used it. Very disappointed as this is not a cheap product.

              I used this product as directed and reapplied every day and I feel as if my nails are weaker than before I started. It bubbles and peels off super easy after you wash your hands only a couple times after application. I have had more nails break since starting to use this product than before and this is completely unacceptable for the price of the product.

              It is recommended to use it for four days. Unfortunately after the second day (second apply) it tooks an hour or longer to dry, and even after that I had marks on the nails.

              Overpriced for what it is

              14 years ago
              I bought this product as my nails are able to grow long rather quickly but they are weak. This product according to the label is supposed to make your nails 4x thicker which would have allowed my nails to grow freely without extensions or overlays. I used the product as per the instructions and even put my hands under the dryer after application. I applied anew coat every day for 4 days and the end result after all of that work was my same nails with a bubbly overcoat that never dried! I am so disappointed with this product and that I wasted my money on something that I will never use again.
