Recently I have tried some of the Sally Hansen nail products.
I love the brush on these, it is quite big so covers the nail well in only a couple of strokes. The formula is thick and creamy on the darker colours and therefore you can get away with one coat if you are using it as a main colour, under nail art or havn't got much time. I got it in the colour 'fiery island so I could use it for some Halloween nail art. The lighter colours may need more than one coat.
These are really pretty, they are a mixture of fine and normal glitter. I was bought mine as a present and it's in the colour 'bejeweled'. The coverage is about the same as a normal glitter polish and lasts well with a good topcoat. You can see it below on my middle finger.
Sally Hansen instant cuticle remover
Not totally sure on this product. It is used to get rid of the excess/dead cuticles. I keep my cuticles very neat so don't think this really did much good for me, however I know that a lot of people swear by it!!
Sally Hansen Diamond Strength Nail Hardener
This is great for using as a base coat. My nails have definitely improved from using this and I have tried several hardeners so can really tell! I sometimes use two coats depending on the shape of my nails (I find my nails break easier when they are squared off). It is a little more expensive than some hardeners but definitely worth it!!
