Vitamins and Hair loss

by in Hair Loss August 12, 2014

The 2 most common forms of hair loss are known as Androgenetic Alopecia(AA) and Telogen Effluvium(TE). When researching these forms of hair loss, the causes are typically rooted in vitamin and micronutrient deficiencies. 

Vitamin A proves critical for maintaining exceptional vision, involvement in immune function, and necessary for cell growth/differentiation. The major attribute of vitamin A is the cell growth because much like other parts of our body, this is how our bodily features are formed. With a lack of vitamin A, cell growth rates decrease and cause the growth of hair follicles to not grow accordingly. 

Similar to anything else that is quantifiable, balance is necessary. Lack of vitamin A will harm hair growth just as much as excess vitamin A consumption. 

Vitamin B7(Biotin) is also a significant factor in hair growth. Typically a lack of this vitamin will be most identifiable when examining the cause of hair loss, thus leading the victims of this deficiency to seek out hair supplements that emphasize the amount of vitamin B they possess. However, in most cases vitamin B supplements for hair loss will overcompensate the amount of biotin needed in order to persuade the consumer into believing more is better despite this not being factual. 

Other notable vitamin/micronutrient regarding hair loss:

  • vitamin C intake is important in patients with hair loss associated with iron deficiency.
  •  vitamin D supplements or topical vitamin D analogues should be considered for patients with AA and vitamin D deficiency
    • Vitamin D deficiency was found in patients dealing with Alopecia
  • The most common nutritional deficiency in the world is iron deficiency, which contributes to TE
    • Iron deficiency is common in women with hair loss
