In our country it is funny if we say we are deficient of the Sun Vitamin i.e. Vitamin D, but it’s a fact. Particularly seen in urban India. We blame it on our life style, environmental factors etc. Ithas a medical significance with respect to many health problems. Inclinical trichology we often see hair loss associated with Vit.D deficiency.
A study was conducted which proved association of Vit. D deficiency with alopecia areata (AA).
Alopecia areata is an autoimmune problem which is often seen in associationwith stress or viral infections or immunisation. In fact there is novalid reason why a healthy human being suddenly starts developing abald patch which either heals on its own or spreads all over toinvolve complete scalp and all body hair eventually leading tocomplete loss of hair. General Trichologists use Tyrosine to treatautoimmune disorders like this.
Theresponse to treatment with Tyrosine rather confirms the autoimmunenature of the disorder.
Duringthe study when the complete blood reports were done a significantfinding showed that all the candidates were seen to have deficiency of Vit. D i.e. serum25-hydroxyvitamin D levels less than 30, irrespective of age and sex.All were also seen to have higher levels of C reactive proteins, oneof the markers of autoimmunity.
Withthis study one can conclude that deficiency of Vit. D can make one prone to Alopecia Areata.
