Excellent product I have always suffered with split nails. Since using this product my. Nails have grown and no longer split. If I stop using it for any reason, I notice the difference. Please don't stop stocking it because I struggle to find it anywhere else! 25 June 2014
Marvellous Mavala I have just rediscovered Mavala after using it in my 30's. I am now in my sixties and it is still the best for peeling splitting nails. 18 June 2014
An absolute godsend! After buying countless nail vitamins, none of which worked, even going to my doctor who had no solution to my peeking nails, I by chance saw this product while browsing at nail varnishes in store. I thought what have I got to lose. I saw results after my first use and was absolutely amazed. After a months use, I can't believe the results. It is a small product but a little goes a long way, so it's excellent value for money. Thank you Mavala! 29 May 2014
A really must have product After reading the other reviews I thought I would give this a go, I had been wearing Gel nails for the last 6 months and my nails were in an awful state, thin, weak, splitting and would not grow the slightest knock would break what little nail I had so when I started using this product did not hold out much hope but no it does work my nails are now growing and like other users I have had to file then because they were getting so long. Also my nail varnish now lasts much longer. Great product in such a little bottle. 17 March 2014
Finally a product that Actually works! I have suffered with weak, thin, peeling nails for years. I have tried everything to stop it but nothing really worked. I saw this product as a last resort and although read it does contain formaldehyde, thought what have I got to loose! I can confirm after only using it for just over a month my nails are the strongest they have ever been and have practically no peeling! The pot is small but can understand why people say it lasts for a year (a little goes a long way!) 5 stars to Mavala, will most defiantly buy again! 18 August 2013
At last! A product that really works! I can confirm what the previous reviewer says: This product really does work. My nails have always been thin and weak, and over about the last three years I've also suffered from peeling and flaking of the top layer, meaning that I couldn't grow my nails at all. Over that time I tried many different products, most of them very expensive, but none of them worked. These were all basically a clear nail varnish, which would peel off with the top layer. This product is different. It is a liquid, which you paint on just the tips. It takes about 30 seconds to dry and seems to have disappeared. To start with you use it twice a week, then once the nails start improving (which they do within about two weeks) you use it once a week to maintain the nails. I've had this product for about 8 weeks now, my nails are much stronger and I've actually had to cut them twice because they were getting too long! The first time I've done that for ages. As this is only applied to the nail tips, a little goes a long way - Mavala claim that this little bottle will last a year, so this is also very good value, at about a third the price of most other products. One thing to note: The Editor's Note says that Mavala products do not contain formaldehyde, however, this one does. You have to be careful not to get it on the cuticles, the skin around the nail etc as they will all thicken. However, if you are happy to use a product carefully, just on the nail tips as directed and have weak or flaking nails, give this a try. 03 February 2013
does work! Bought this product as a last chance for my weak nails. You can not imagine how bad they were - I did not make a manicure for last few years - it was impossible to do because I always had short ugly nails. This nail hardener just brilliant! After only 2 appliances I noticed significant improvement! To be honest I did not believe it could help but now I can confirm - it really works! even for the most difficult cases like mine! :) 05 March 2012
