Oysters Hair loss or dandruff is due to low level of hormone androgen production. Include oysters in your diet as they are rich in zinc, which further helps in the production of androgen and hence fights against hair fall and dandruff. Besides, it also helps your locks retain shine and health.Oyster is the common name for a number of different families of salt-water bivalve molluscs that live in marine or brackish habitats. In some species the valves are highly calcified, and many are somewhat irregular in shape. Many, but not all, oysters are in the superfamily Ostreoidea.
