If you’ve been wrestling with hair loss and poor hair growth and your trichologist has ruled out hormonal oscillations or any underlying medical condition, the cause for the hair loss most definitely will be nutrient deficiency. Your doctor will identify which specific nutrient is inadequate in your diet and  is the chief cause for your hair loss. Your blood work will provide a clear picture of which vitamin or mineral is inadequate in your body – your doctor will ask you to evaluate your calcium, iron, B 12 and D 3 levels – and he will prescribe the necessary supplements to correct the insufficiency and you will be on the road to healthy hair!
