4. Sephora Nail Colour
A complete collection of nourishing, nail strengthening treatments. Whether you prefer your nails long or short, lacquered or natural, healthy nails are your first step. Sephora's complete collection of nailcare must-haves is all you need to fortify, prep, and finish off your look.
I LOVE the Red Light and Stormy Pink versions of this... Sephora have always been brilliant for choosing gorgeous colours. This contains vitamins to help strengthen your nails, and keep them in excellent condition, and looks divine while it's at it. And for $6, you should be able to afford all of them! Well, maybe not ALL of them, but quite a few! ;)
