Vitamin A

• Vitamin A is a fat soluble vitamin that is very important in the preservation and support of healthy skin and hair. Vitamin A is responsible for balanced sebum production. A deficiency in vitamin A can cause dry, brittle hair due to a decrease in oil production from the hair follicles. A lack of vitamin A also can cause the skin to become dry and dull with a flaky and scaly appearance.
  
  The recommended dietary allowance for vitamin A is 2,333 IU for women and 3,000 IU for men. Food sources of vitamin A are liver, eggs, colorful fruits, and vegetables and dark leafy vegetables.
  
  

Vitamin C

• Vitamin C is a water soluble vitamin that increases circulation and produces the connective tissue collagen. Without vitamin C, the scalp does not get the circulation it needs to support healthy hair growth. In addition to this, skin cells do not regenerate as quickly, and wrinkles form on the skin due to the break down in the connective tissue and a decrease in the production of collagen.
  
  Because vitamin C is water soluble, it is not stored in the body and must be replenished daily. For healthy skin and hair, an average of 3,000 mg per day is necessary. Food sources of vitamin C are citrus fruits, dark leafy vegetables, tomatoes and potatoes.
  
  

Vitamin E

• Vitamin E is the most recognized vitamin for beautiful skin and hair. Vitamin E is a fat soluble vitamin that protects cells against free radical damage from environmental factors such as the sun. Vitamin E lubricates cell membranes and speeds up cell regeneration to support new skin and hair growth. The scalp can become flaky and the face can become extremely dry and rough without sufficient vitamin E intake.
  
  The recommended dietary allowance for vitamin E is 30 IU. Food sources for vitamin E are vegetable oils, margarine, nuts, seeds and leafy vegetables.
