Q & As

Rated 4.8 out of 5 by 13 reviewers.
Rated 4 out of 5 by Good results I've used this for years with varying results. I naturally have very very soft bendy nails. Recently it seems to work better than previously, I'm not sure if this is due to a change in the product or whether my nails are stronger as I've grown older and nearer to the menopause. At the moment though, my nails look fab!! 01 July 2015
Rated 5 out of 5 by Truly Indispensable As a life-long nail biter and in my desire to have lovely nails this little bottle brings big results. Used exactly as it says, your nails will stop splitting and become strong and before you know it you have beautiful long nails, all ready for the latest colours. Wow, you will feel so much better. 03 June 2015
Rated 5 out of 5 by I was pleasantly suprised! This is a very interesting liquid. It does make your nails stronger. I had fake nails for a long time and took them off about six month ago. My nails were in a very bag state. I was using OPI nail hardener. Which was ok, but as my nails were so weak I added this product to my routine. I use it twice a week, let it set for few minutes and then I apply nail hardener on top. My hands look good, my nails are natural and don't pill off or break. I make sure I file them twice a week before re-applying my products. A good buy, will be buying it again. Also I never do my house work without gloves. 02 June 2015
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
