Reversible hypopigmentation of the hair can be seen in nutritional deficiencies protein-energy malnutrition and diseases of chronic loss of protein. Copper and iron deficiency also can cause graying of hair.

To avoid hair thinning and greying, iron and copper are one of the most essential nutrients.

As we get older, the pigment cells in our hair follicles gradually die. When there are fewer pigment cells in a hair follicle, that strand of hair will no longer contain as much melanin and will become a more transparent color — like gray, silver, or white — as it grows.

Rashes associated with aplastic anemia usually appear as tiny red or purple dots under your skin (petechiae). The dots can form large patches but aren't usually itchy or painful.
