Low zinc thins hair: It is usually the lack of zinc or low zinc levels that causes thinning of the hair. The most important source of zinc in your diet is meat although you can google the other sources.

Zinc ; Hair Loss: Some scientific theories suggest that excessive levels of zinc in the body can have negative effects by boosting male hormone testosterone production. This will lead to increased Dht levels causing hair thinning and loss.
