This product has worked amazingly for myself and my friends. I've only been using it for two weeks and I'm already seeing amazing results!
The product works by joining the layers in your nails together to form one thick strong layer, this stops flaking, breaking and splitting.
It's is very important to only apply a tiny amount to the very tip of your nails, otherwise it begins to thicken the rest of the nail, which isn't very nice! It's essential to apply a little bit of Vaseline to the skin surrounding the nail, to stop the product hardening the skin, which makes it all crusty, ew!
