If you're unfamiliar with NailPolishCanada.com, it is a website that will fill all your nail needs. They have nail art tools and a huge collection of nail polishes that range from indie brands to more well known brands. They offer free shipping to all orders within Canada, so that is a pretty awesome bonus.
According to the official website, Duri Rejuvacote is "will heal and cure your split, cracked and acrylic destroyed nail in a matter of weeks. You will enjoy the look and feel of strong, vital, natural nails." I haven't tried a lot of nail strengthening polishes, but compared to how my nails were the previous weeks without any treatments, I definitely notice the difference. Before I tried this product, my nails were quick to break and easy to bend with very little pressure. The affects of this treatment were pretty immediate. As soon as the two coats dried, my nails were hardened and felt protected. Now, when I try to push my nails downwards with the same amount of pressure, it doesn't budge. My nails just feels a lot stronger after applying this. It may not "look like it" because parts of my nails look a little translucent, but I can tell you it feel a lot more strengthened than it was from a few weeks ago. So this product totally gets my recommendation.
