Q & As

Rated 4.9 out of 5 by 10 reviewers.
Rated 4 out of 5 by Works well About a month in and already most of my nails have improved massively, much stronger, with the exception of my thumb nail which is still splitting/flaking, but hoping will improve with time as it grows out. Avoiding getting solution on surrounding skin etc can be tricky if to start with your nails are short as mine were, but much easier as nails lengthen. Am hopeful that I will finally have presentable nails as no other treatments have worked. 01 April 2015
Rated 5 out of 5 by A nail hardener that works Mavala Nail Hardener is a very good product and that really works to harden tips of nails work if used regularly to begin with and then say at monthly intervals. It is easy to use and does what it says on the bottle. Although it looks a small bottle it lasts for a very long time. Probably buy one a year. 25 March 2015
Rated 5 out of 5 by This is the one I have used this product for many years.It is excellent.Lasts a long time, and really works I have many compliments about my beautiful nails.and I attribute them to Mavala products. 05 November 2014
Rated 5 out of 5 by 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
Rated 5 out of 5 by 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
Rated 5 out of 5 by 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
Rated 5 out of 5 by 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
Rated 5 out of 5 by 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
