Kalyon Nail Hardener
If your nails get broken so easily like mine, I can recommend this product to you. It’s amazing. It made my nails hard enough in a week. It doesn’t damage your natural nails like nail polishes do. I apply it first on my nails and then I apply nail polish on it. Sometimes I only use this nail hardener alone. It works both ways. I recommend using this product only, without nail polish. I’m sure you will like this product.
