How Vitamins Affect Your Hair Growth

Your hair follicles are among the most metabolically active tissues in your body. They’re constantly cycling through phases of growth, rest, and shedding, and this process requires a steady supply of nutrients to function properly. When your body doesn’t get enough of certain vitamins, it prioritises vital organs over hair growth, and your follicles suffer as a result.

The NHS recognises that nutritional deficiencies can contribute to hair loss, though it’s worth noting that they’re rarely the sole cause. More often, vitamin deficiencies work alongside other factors like stress, hormonal changes, or genetic predisposition to trigger or worsen hair thinning.

The Key Vitamins Linked to Hair Loss

Vitamin D

Vitamin D deficiency is surprisingly common in the UK, particularly during the winter months when sunlight is scarce. According to the NHS, around one in five adults has low vitamin D levels. This vitamin plays a crucial role in creating new hair follicles and maintaining the hair growth cycle.

Research has shown a correlation between low vitamin D levels and both male and female pattern hair loss, as well as alopecia areata. Your hair follicles have vitamin D receptors, and when these aren’t adequately activated, it can disrupt the normal hair growth cycle.

B Vitamins, Particularly B12 and Biotin

B vitamins are essential for creating red blood cells, which carry oxygen and nutrients to your scalp and hair follicles. Vitamin B12 deficiency is particularly problematic and can cause various symptoms, including hair loss, fatigue, and weakness.

Biotin (vitamin B7) has become something of a poster child for hair health, though true biotin deficiency is actually quite rare in people eating a balanced diet. That said, certain conditions can affect biotin absorption, and supplementation may help in specific cases.

Iron

While technically a mineral rather than a vitamin, iron deficiency deserves mention as it’s one of the most common nutritional causes of hair loss, especially in women. Iron deficiency anaemia affects your body’s ability to produce haemoglobin, which means less oxygen reaches your hair follicles.

The NHS states that iron deficiency is the most common nutritional deficiency in the UK, affecting particularly women of childbearing age. If you’re experiencing hair loss alongside fatigue, pale skin, or shortness of breath, iron deficiency could be the culprit.

Vitamin A

Vitamin A is something of a Goldilocks vitamin when it comes to hair health. Too little can cause hair loss, but too much can have the same effect. This vitamin helps your skin glands produce sebum, the oily substance that moisturises your scalp and keeps hair healthy.

However, vitamin A supplements should be approached cautiously. The NHS advises that having more than 1.5mg of vitamin A per day from diet and supplements combined could have harmful effects.

Vitamin E

Vitamin E is an antioxidant that helps protect your hair follicles from oxidative stress. Some studies have suggested that people with alopecia areata have lower levels of vitamin E in their blood, though more research is needed to fully understand this connection.

Recognising the Signs of Vitamin Deficiency Hair Loss

Vitamin deficiency hair loss typically presents differently from genetic hair loss. Rather than following a specific pattern (like a receding hairline or crown thinning), it often causes diffuse thinning across the entire scalp. You might notice more hair in your brush or shower drain, or find that your ponytail feels thinner.

Other signs that vitamins might be involved include:

• Hair that feels brittle or breaks easily
• Slower hair growth than usual
• Changes in hair texture
• Accompanying symptoms like fatigue, weakness, or changes in skin health
• Recent dietary changes or restrictive eating patterns

It’s worth noting that hair loss from vitamin deficiency doesn’t happen overnight. Your hair follicles have a lag time, so you might not see the effects until several months after a deficiency develops.

Getting a Proper Diagnosis

If you suspect vitamin deficiency might be contributing to your hair loss, the first step is getting properly tested. Your GP can arrange blood tests to check levels of vitamins D, B12, iron (including ferritin, which measures iron stores), and other nutrients.

Self-diagnosing and loading up on supplements isn’t advisable. Some vitamins can be harmful in excess, and you might waste time and money on supplements you don’t actually need. Plus, what looks like vitamin deficiency hair loss could actually be another condition that requires different treatment.

The NHS recommends speaking to your doctor before taking vitamin A supplements or any vitamin D supplement containing more than 100 micrograms. They can help you understand whether supplementation is appropriate and at what dose.

Treatment Options for Vitamin Deficiency Hair Loss

Once you’ve identified specific deficiencies, treatment usually involves a combination of dietary changes and targeted supplementation.

Dietary Approaches

Improving your diet should always be the foundation of treatment. Good food sources include:

• Vitamin D: Oily fish, red meat, liver, egg yolks, and fortified foods
• B vitamins: Meat, fish, dairy products, eggs, and fortified cereals
• Iron: Red meat, beans, nuts, dried fruit, and fortified cereals (pair with vitamin C for better absorption)
• Vitamin E: Nuts, seeds, and vegetable oils

However, diet alone isn’t always enough, particularly for vitamin D in the UK climate. The NHS recommends that everyone consider taking a daily supplement containing 10 micrograms of vitamin D, especially during autumn and winter.
