Hair Fall and Nutrition: Which Deficiencies Are Common Culprits

Hair Fall Is Often a Nutrition Signal

While hair fall can have genetic, hormonal, or stress-related causes, nutritional deficiency is one of the most common and most correctable contributing factors — particularly iron, protein, and certain B vitamins.

Nutrients Most Often Linked to Hair Fall

• Iron — low iron is one of the most well-documented nutritional causes of increased hair shedding, especially in women
• Vitamin B12 — deficiency can affect the health of the scalp and hair growth cycle
• Protein — hair is largely made of protein, and inadequate intake can weaken the hair shaft over time
• Zinc — plays a role in hair tissue growth and repair

Where to Start

Rather than guessing, a simple blood test for iron and B12 levels gives a clear answer. If low, iron with vitamin C and plant-based B12 are both practical, daily-habit ways to correct a genuine deficiency rather than a generic "hair vitamin" that may not target your actual gap.

Zinc From Food

Pumpkin seeds are one of the more accessible dietary sources of zinc, easy to add as a daily snack.

If hair fall is sudden, severe, or comes with visible bald patches, see a dermatologist — nutrition addresses one contributing factor, not every possible cause.
