My nails are half shiny...half not.

[bitesize]

This may be in the wrong forum, heh. It didn't feel quite right in fashion&beauty. But basically my fingernails nails are smooth and shiny on the top half...and then noticeably not at the bottom half, near the cuticle; they look all dull. Even when I buff them, they look as though I've put clear nail varnish on just half of my nail. This problem isn't taking over my life or anything, but why is this?? Am I deficient in some sort of vitamin?? :/

As the dull part of the nail is nearer the cuticle, that implies that it's recently begun growing that way. Can you think of any diet changes you've made in the past few weeks?
A quick Google search suggests a deficiency of B vitamins which can be found in dark green veggies like broccoli and spinach
If buffing doesn't work, try using clear nail varnish to hide the dullness
