Nails are a substructure of the outer layer of the skin (epidermis).
They are composed mainly of keratin, a type of protein. Healthy nail
beds are pink, indicating a rich blood supply. Change or
abnormalities in the nails are often a result of nutritional deficiencies
or other underlying conditions.
White bands across the nails are an indication of protein
Fragility: A deficiency of the B vitamins causes
fragility with horizontal and vertical ridges. Insufficient intake
of vitamin B12 leads to excessive dryness.
(nails that develop in a concave shape) or vertical ridges:
White spots: Zinc deficiency.
nails: a lack of sufficient hydrochloric acid in the stomach.
of the things you could be missing is biotin, a B-Complex vitamin that is
necessary for your body to process the fat and protein that you eat.
Biotin can be destroyed by certain food processing techniques such as
canning and heat curing.
You do need to make sure that you aren't
exposing your nails to harsh chemicals or using too much polish remover
both of which deprive your nails of moisture.
