Vitamin & Mineral Deficiencies – The Hidden Cause of Hair Fall
When it comes to hair fall, nutrient deficiencies are one of the most overlooked causes. Many people focus on expensive hair care products, but the reality is that your hair is built from within—and if your body is missing key vitamins and minerals, your hair simply won’t grow strong, thick, or healthy.
Hair follicles are highly nutrient-sensitive, meaning even a slight deficiency can lead to excessive shedding, slow regrowth, thinning, or premature graying. Since hair isn’t a “priority” organ for survival, your body diverts nutrients elsewhere when it’s lacking essential vitamins or minerals.
If you’ve been experiencing increased hair fall, brittle strands, slow regrowth, or scalp issues, it’s time to check for potential deficiencies.

Reminder: Before supplementing any of these nutrients, it’s essential to consult with a healthcare provider and perform blood tests to identify any deficiencies specific to your condition. A professional will help you determine the best course of action, as not all hair loss is related to nutrient deficiencies, and over-supplementing can lead to side effects.
📌 Quick Reference: Vitamin & Mineral Deficiencies That Affect Hair
Nutrient |
Deficiency Symptoms |
How It Affects Hair |
Food Sources |
|
Iron |
Fatigue, weakness, dizziness, pale skin, brittle nails |
Leads to hair shedding and thinning due to reduced oxygen supply to hair follicles. |
Red meat, spinach, lentils, fortified cereals. |
|
Vitamin D |
Bone pain, muscle weakness, fatigue, depression |
Hair loss (especially around the crown area) due to poor follicle cycling and immune response. |
Sunlight, fortified milk, eggs, salmon, mushrooms. |
|
Vitamin B12 |
Fatigue, weakness, numbness, tingling, mood changes, pale skin |
B12 is vital for cell production; deficiency can cause premature graying and hair thinning. |
Eggs, fish, dairy, fortified cereals. |
|
Vitamin A |
Dry skin, frequent infections, night blindness |
Essential for sebum production on the scalp, and deficiency can result in dry, brittle hair. |
Sweet potatoes, carrots, spinach, kale, eggs. |

Zinc |
Skin rashes, frequent colds, loss of taste and smell, wounds taking longer to heal |
Zinc plays a role in hair growth and repair. Deficiency leads to hair loss and slower regrowth. |
Meat, shellfish, legumes, seeds, nuts. |
|
Biotin |
Thinning hair, brittle nails, skin rashes, fatigue |
Important for keratin production; deficiency causes thinning hair, hair breakage, and slow regrowth. |
Eggs, almonds, sweet potatoes, spinach, oats. |
|
Omega-3 |
Dry skin, brittle hair, dandruff, scalp irritation |
Omega-3s reduce scalp inflammation and promote healthy hair follicles. Deficiency leads to hair shedding and dry, brittle hair. |
Salmon, mackerel, chia seeds, flaxseeds, walnuts, algae oil. |
|
Vitamin C |
Scurvy (bleeding gums, bruising), dry skin, fatigue |
Essential for collagen production; deficiency can cause hair thinning and weak, lifeless hair. |
Citrus fruits, bell peppers, broccoli, strawberries. |
|
Folic Acid |
Fatigue, irritability, shortness of breath, mouth sores |
Necessary for cell regeneration; deficiency can cause dull hair and hair loss. |
Leafy greens, legumes, fortified grains. |
|
Magnesium |
Muscle cramps, fatigue, irritability, poor sleep |
Magnesium is involved in protein synthesis. Deficiency can cause hair loss and thinning. |
Almonds, spinach, avocados, bananas, seeds. |
|
Copper |
Fatigue, pale skin, hair discoloration, brittle bones |
Copper supports melanin production; deficiency can cause premature graying or lack of hair pigment. |
Shellfish, nuts, seeds, whole grains, beans. |
