I have found a product that strengthens my nails in one coat and it is a great base coat for any nail polish too.
I love that is protects my nails from my Mum and housework duties which often strip my hands of any moisture (yes I know I should wear gloves!) and enables my nails to grow to a nice length so that they look presentable and healthy whilst I am working.
Thanks Sally Hansen.
I also keep them really moisturised by using either Jessica Phenomen Oil:
Or Solar Oil
And of course by wearing household gloves!!! (New Year's Resolution)
