Expert explains how vitamin B12 levels influence hair follicle strength and growth

Dull or falling hair often serves as a silent indicator of internal nutritional gaps, specifically regarding vitamin B12, also known as cobalamin.

Dermatologist Dr Priyanka Kuri notes that this vitamin is vital for energy metabolism and brain function. Beyond these roles, it is fundamental for hair health.

Dr Kuri explains, “This increased blood supply strengthens hair, promotes healthy growth, and reduces breakage. People with a greater B12 deficiency are more likely to experience hair loss and damage.” Vitamin B12 supports the body by:

• Supporting healthy hair follicles through red blood cell formation and oxygen delivery.
• Stopping hair loss by preventing the disruption of the DNA-dependent growth cycle.
• Strengthening hair by raising keratin levels to reduce thinning and breakage.
• Slowing down the process of hair turning grey prematurely.

How to use vitamin B12 for hair?

Adults typically require a daily intake of 2.4 mcg, though those with deficiencies may need higher doses under medical supervision. To raise levels naturally, individuals can utilise:

• Dietary intake: Consume eggs, fish, and milk products.
• Supplements: Use capsules or sublingual drops if absorption is difficult.
• B12 injections: Prescribed by doctors for severe cases or anaemia.
• Topical applications: Utilise lotions or balms containing B12 for external support.

What foods have the highest B12?

Natural sources remain the most effective way to support growth. High-B12 options include animal sources like chicken and yoghurt, while vegetarians can look to fortified cereals and yeast spreads.

Organ meats and shellfish, such as clams, also provide concentrated amounts. By ensuring adequate B12 intake, individuals can maintain vibrant, strong hair while delaying the onset of silver strands.
