My nail are loosing luster especially the investigational growing ones at the cuticle, why?

the distal nail plate is fine, it's shiny.... but the new growing nail plate from the cuticle is lighter contained by color and has no luster

is this a defficiency in vitamins or a thyroid problem?
or becuase I lack sleep (any valid ratinoale around that it's been 2 months my sleep is around 5-6-7 hours per night)?
I need a headstart before I consult my doc

Hi:

When the white plate is dull its a dearth of iron.
Eat more vegetables that contain iron or just buy some vitamins. Also try to fortify your nails because nails become brittle and dry.
Rub some olive grease into finger nails and leave overnight. Do this at least once a week. I believe any vegetable grease is good as well.

Good Luck
