| - Quick Take
A social media post claims that hair health can reveal nutrient deficiencies and hormonal imbalances. Our fact check shows this is mostly false.
The Claim
A Facebook post claims that different hair problems happen because of specific nutrient deficiencies or hormone issues. It says dandruff means low zinc, thin hair means low iron, and grey hair comes from a lack of Vitamin B12 or D. It also suggests that brittle hair is due to low protein or Omega-3, and sudden hair fall is caused by high cortisol or testosterone levels.
Fact Check
Does excess dandruff always mean a zinc deficiency?
Not really. While zinc plays a role in skin and scalp health, dandruff primarily occurs due to a fungal overgrowth (Malassezia), excess oil, or sensitivity to hair products. Other factors like stress and weather changes can also contribute. Zinc deficiency may worsen dandruff, but it’s not the sole cause.
Dr Rashi Soni, Co-founder and Consulting Dermatologist at Rashi Hospital in Mumbai, says, “Dandruff is mostly caused by an overgrowth of a yeast-like fungus called Malassezia, along with factors like excess oil production, dry scalp, or sensitivity to hair products. While zinc helps control scalp inflammation and oil balance, dandruff can also be triggered by stress, weather changes, and poor hair hygiene. Simply taking zinc supplements won’t always fix the problem—using the right anti-dandruff shampoo and maintaining a healthy scalp routine is key.”
Are thin hair and iron deficiency always linked?
Not necessarily. Iron is crucial for hair growth, and severe deficiency (anaemia) can lead to hair thinning. However, genetics, hormonal imbalances (like thyroid disorders), and stress also affect hair thickness. A balanced diet with adequate iron helps, but thinning hair is not always due to iron deficiency alone.
Dr Ekansh Shekhar, Dermatologist, Cosmetologist, Trichologist, and Aesthetic Medicine Consultant in Lucknow, states, “Iron is essential for healthy hair growth because it helps deliver oxygen to hair follicles. Severe iron deficiency, like in anaemia, can lead to thinning hair. However, not all cases of thin hair are due to low iron—genetics, hormonal imbalances, stress, and poor hair care also play a role. It’s important to get tested before taking iron supplements unnecessarily.”
On a related note, some people suggest eating three dates a day to combat hair loss, but this may not work for everyone.
Does premature greying indicate vitamin B12 or D deficiency?
Sometimes, but not always. Premature greying depends on genetics, oxidative stress, or deficiencies in Vitamin B12, Vitamin D, and copper. However, many people with adequate nutrient levels experience early greying due to hereditary factors. Sun exposure helps maintain Vitamin D levels, but it doesn’t guarantee prevention of grey hair.
Is brittle hair caused only by protein or Omega-3 deficiency?
Not exclusively. Protein is essential for hair strength, and Omega-3s help maintain scalp health and hydration. However, hair breakage can also result from excessive heat styling, harsh chemicals, dehydration, and medical conditions like hypothyroidism. While a protein-rich diet supports hair health, brittleness has multiple causes.
Does sudden hair loss always indicate high cortisol or testosterone levels?
No. Stress (which raises cortisol) and hormonal imbalances can contribute to hair loss, but so can factors like post-pregnancy changes, certain medications, autoimmune diseases (like alopecia areata), and nutrient deficiencies. A sudden increase in hair fall requires a medical assessment to determine the underlying cause.
THIP Media Take
The claim that hair health can reveal nutrient deficiencies is mostly false. While nutrients and hormones play a role in hair health, the post oversimplifies complex biological processes. Hair issues can result from multiple factors, including genetics, environmental stressors, and medical conditions. Anyone experiencing significant hair changes should consult a doctor rather than self-diagnose based on social media claims.
