Several different vitamin or mineral deficiencies can cause dry
hair. To treat dry hair, try taking a multivitamin with 100
percent of the daily value of the essential vitamins. A
multivitamin and mineral combination may provide some added
coverage for possible deficiencies.

It`s been shown that too little biotin and pantothenic acid
(both B-complex vitamins) can lead to dry hair. Shampoos and
hair treatment products commonly contain pantothenic acid (or
pantothenol). But evidence supporting the benefits of
pantothenic acid for dry hair and hair loss is very weak.
Also, some people with hair loss do show low blood levels of
biotin. While the evidence isn`t strong, it may be worth it to
try taking supplements of biotin and pantothenic acid for
bothersome hair conditions that are not helped by hair
treatment products. Iron and Zinc also affect hair growth.
Iron is an important trace mineral that is found in every cell
of the body, including hair, usually combined with protein.
Zinc is an essential mineral that is found in almost every
cell, including our hair. It stimulates the activity of
approximately 100 enzymes, which are substances that promote
biochemical reactions in your body. Zinc supports a healthy
immune system, is needed for wound healing, helps maintain
your sense of taste and smell, and is needed for DNA synthesis.
