Q & As

Rated 4.7 out of 5 by 17 reviewers.
Rated 5 out of 5 by IT WORKS.... As I have got older my nails have become weaker and splitting to use polish was a NO NO , but thanks to a very helpful assistant at John Lewis I tried Mavala my nails have become harder , grow so much quicker and can use polish again without the worry of my nails splitting. EXCELLENT PRODUCT. 16 September 2015
Rated 4 out of 5 by Does the Job Very easy to use, dries quickly and seem to have made my nails more resistant to splitting and breaking. 08 September 2015
Rated 4 out of 5 by the old ones are the best I used to use this product many years ago, and had not been able to find it anywhere as time went by. I started to use other products, none of which seemed to work for me. I was delighted to find mavala for sale in John Lewis's recently. Already my nails are very much improved. 21 July 2015
Rated 4 out of 5 by Some improvement This product does harden my nails but after 6 applications over 3 weeks does not stop them from flaking. 07 July 2015
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
