Hyderabad: Hair fall is not always about the shampoo, oil or hair care products you use. Sometimes, the problem may lie within the body, with nutritional deficiencies affecting hair strength, texture and overall health. Certified nutritionist Kiran Kukreja highlights the importance of looking beyond external hair care and paying attention to the nutrients the body needs.
Zinc is one of the key nutrients associated with hair health. It plays an important role in cell growth and tissue repair, and low levels may contribute to hair loss. Adequate zinc intake supports normal hair growth and follicle function.
Vitamin D is another nutrient worth considering when dealing with persistent hair fall. Low vitamin D levels have been associated with certain types of hair loss. Maintaining adequate levels through a balanced diet, appropriate sunlight exposure and supplements when medically advised can support overall health.
Ferritin, a protein that stores iron in the body, is also important for hair health. Low ferritin levels may indicate depleted iron stores, which can contribute to hair shedding. Iron deficiency is a potential cause of hair loss, particularly when accompanied by other symptoms.
Vitamin B12 helps maintain healthy blood cells and supports the functioning of the nervous system. A deficiency can lead to anaemia and may contribute to hair-related concerns in some people.
Kukreja also highlights the importance of thyroid health, as hormonal imbalances can affect the hair growth cycle. She encourages people experiencing persistent hair fall or weak hair to focus on internal nutrition alongside external care.

Rather than taking supplements without guidance, people experiencing ongoing hair fall should consult a healthcare professional to identify possible deficiencies through appropriate tests and determine the right treatment.
