Nutrition deficiency affects both hair structure and hair growth, say, researchers. Malnutrition of protein, calorie, and micronutrient deficiency can drastically affect hair growth. 

Though many people investigate whether nutritional supplements can help foster natural hair growth, the links are yet a bit complex. That being said, there’s no denying that nutrition does play a significant role in hair loss.  


Iron deficiency is the most common deficiency that can contribute to hair loss. Researchers suggest that deficiency of Iron can lead to a condition called Telogen Effluvium (TE), a type of hair loss caused by a disruption in the normal hair growth cycle.

In addition, some genes that contribute to the growth of hair follicles are known to be regulated by Iron. Even hair loss specialist, Dr. Jacono suggests that people should foster their intake of Iron for natural and heavy hair growth. 

Moreover, Iron stimulates the quick blood supply throughout the body, which, in turn, prevents the chances of infection and hence prevents the symptom of hair loss, which is quite familiar with some medical conditions. 


Zinc is an essential mineral known, which is needed by many cells and enzymes in the body for immune function, cellular division, protein synthesis, and more. Research suggests that people with hair loss had a lower zinc level than people without much hair loss. 

Consistent zinc intake promotes the faster and natural growth of hair follicles, which otherwise get slowed down.

Lack of protein intake can cause hair thinning and hair loss. Protein and amino acids are known as the building blocks of the body due as they repair and make new cells. Besides, they provide that extra strength to the strands and allow them to hold on to moisture. 

According to hair specialists, feeding your body with a wide range of protein foods like red meat, fish, dairy products, etc., is vital for providing the balance your hairs need.
