Vegan Diets Are Great For The Environment- But What About Your Hair?
Veganism has moved from niche lifestyle to mainstream culture.
In the UK alone, millions now follow a plant-based diet, motivated by environmental, ethical, and health benefits.
But a question we increasingly hear in clinic consultations is:
Can a vegan diet contribute to hair loss?
The short answer:
Sometimes — but not in the way people think.
Hair loss is rarely caused by veganism itself.
It’s caused by nutrient imbalance, which simply becomes easier to fall into when certain foods are removed without proper replacement.
Let’s break down the science.

The Nutrients Your Hair Actually Needs
Hair is biologically non-essential tissue.
That means when your body lacks nutrients, it diverts resources to vital organs first — and your hair follicles enter a resting phase (telogen).
The most common deficiencies linked to shedding:
Iron
Iron deficiency is one of the strongest nutritional links to hair thinning.
Animal sources contain heme iron, which absorbs efficiently.
Plant sources contain non-heme iron, which absorbs poorly unless paired with Vitamin C.
Low iron levels are strongly associated with:
- diffuse thinning
- increased shedding
- slower regrowth
Public health figures such as Dr Hilary Jones have warned that poorly planned vegan diets may increase the risk of iron-related hair loss — particularly in men already predisposed to thinning.
Vitamin B12
B12 supports red blood cell formation and oxygen delivery to follicles.
Deficiency symptoms often include:
- fatigue
- brittle hair
- thinning hairline
Because B12 is naturally found in animal products, vegans must supplement or consume fortified foods.
Zinc & Protein
Hair is made primarily from keratin protein.
Low intake can lead to:
- weak hair shafts
- breakage
- slowed growth cycles
Plant diets can supply enough protein — but only when properly balanced across legumes, grains and nuts.
The Thyroid Connection
The Mayo Clinic notes that thyroid dysfunction is a major trigger of hair shedding.
Here’s where diet matters:
A sudden shift to high soy consumption combined with low iodine intake may interfere with thyroid hormone regulation — particularly in individuals genetically predisposed to thyroid issues.
This does not mean soy is harmful.
It means dietary balance matters.
Important Reality: Most Male Hair Loss Is Genetic
Nutritional shedding causes temporary diffuse thinning.
Male Pattern Baldness causes permanent follicle miniaturisation.
If you notice:
- receding temples
- thinning crown
- horseshoe pattern
You are almost certainly experiencing androgenetic alopecia — not dietary shedding.
In these cases, changing diet will not reverse the process.
The Psychological Impact
Many men spend years trying:
- supplements
- shampoos
- dietary adjustments
- styling tricks
But once follicles have miniaturised, they cannot recover naturally.
That’s when frustration begins.
