## Customer Reviews

### ⭐⭐⭐⭐⭐ It renewed mine !
*by E***S on 26 October 2012*

I' ve had problems with splitting and peeling nails for ages - not the greatest disaster in the world, I know, but they would get snagged on clothes, and everything, rip and become sore. I'd tried SO many products, then saw this here on Amazon. It IS quite expensive but ignore that because this IS good stuff, which WORKS, so it is worth the extra outlay !.I have only 2 negative comments to offer -1) when applied the nails can look a little greyish, but underneath they are getting better !.2) The application procedure for this is simple, and easy to do, BUT mathematically the makers figures of a 25 day " course " just don't add up - and I'm an Accountant so CAN add up, and multiply !. I contacted the Dr Lewinn site direct about this aspect ,but heard nothing in response.Never mind - I now have nails the length I choose, rather than how long they would grow before flaking etc., and I used to HAVE to wear clear nail varnish to offer some protection - now I don't have to !.Highly recommended !.POSTSCRIPT:-I still rate the efficiency of this product in fulfilling it's advertising, and VERY highly at that, BUT unfortunately I have found that - apart from the very first 3 week " program " - after which my nails DID look fab - that I am allergic to one ( or more or a combination ) of the ingredients, and that just touching my face with nails wearing this causes redness, itching and swelling !!!.

### ⭐⭐⭐⭐⭐ MIRACLE CURE
*by L***G on 18 July 2012*

My nails were peeling and I was unable to grow them for the last few years (having had lovely long nails up until my mid 40s). I guess the change may have been due to changes in hormones? I wanted to wait until I had given this product an opportunity to work before I wrote a review. I used it for four weeks (applied two coats on first day of the week, then one coat for the next five, took it off on the sixth day evening and started again on day seven morning). I found that from the first application, my nails were harder and did not break off. My nails looked in good condition and I was even asked whether I was wearing gel nails (as the more coats you apply, nails take on an attractive opaque appearance). The instructions say that this product is not designed for continuous use, however it does say on the dr lewinns website that you can use this product as a base coat. I now use two coats as a base for coloured nail polish and my nails continue to grow stronger. I have recommended it to friends who are equally pleased with their results. I have tried other products in the past (nail varnishes, creams, change of diet etc) which have not worked, so please don't waste your money on alternatives as this product is superb.

### ⭐⭐⭐⭐⭐ Best nail strengthener you can get
*by B***Y on 5 April 2014*

I must have tried every single nail strengthener on the market. All the well known major brands and some less well known and none of them made any real difference to my nails.Then I tried this and it actually worked! Okay, my nails are not film star perfect, but they are 100% better than they were before I started using this and are now at a length I can wear nail polish and be proud of them.The only thing I did find was that the instructions tell you to use this for around 3 weeks or so and then have a week or two off. I found when I tried this, my nails deteriorated immediately I stopped using it. So I am afraid I wear it the whole time (no adverse effect and have been doing this for a couple of years!).Well worth trying.
