Vitamin B: The Impact of Diet on Curly Hair Health

Diet is a fundamental pillar of healthy hair. What we eat directly affects the quality and vitality of our hair. For curly hair, which is often more fragile and prone to dryness, a balanced diet rich in nutrients and vitamins is essential. The specific needs of this textured hair include nutrients that support hydration, repair and protection against external aggressors.

Because of its structure, curly hair tends to absorb less sebum, which makes it more vulnerable to dryness. Frizz and breakage are also recurring problems for these hair types. A suitable diet can help meet these needs and strengthen hair health in the long term.

B vitamins, often called "hair vitamins", play a fundamental role in maintaining and improving hair health. They work on several levels, strengthening hair structure, stimulating growth and promoting overall hair vitality. Among these vitamins, some stand out for their particularly beneficial effects:

• B7 (biotin): This vitamin, nicknamed the "beauty vitamin", is essential for hair health. It stimulates hair growth by acting directly on the hair follicles. Biotin is involved in the production of keratin, a key protein that forms the main structure of hair. By strengthening this structure, it helps reduce breakage and improve hair texture, which is particularly beneficial for curly hair that is often fragile and prone to dryness. Studies show that biotin can also help increase hair elasticity, making it more resistant to external aggressions. 
• B12 (cobalamin): Essential for the formation of red blood cells, vitamin B12 plays a key role in oxygenating the scalp. Good blood circulation allows hair roots to receive the nutrients they need to produce strong, thick hair. A B12 deficiency, common among people following vegetarian or vegan diets, can lead to various hair problems, such as excessive hair loss, slower growth, a dry scalp and loss of shine. 

By including these two vitamins in your diet, you can significantly improve the health of your hair and prevent many of the problems linked to its fragility.

To include these vitamins in your diet:

• Vitamin B7: Found in eggs, nuts and avocado, these foods are easy to add to your daily meals.
• Vitamin B12: Found mainly in fish, meat and dairy products. For people following a vegetarian or vegan diet, fortified foods or supplements may be needed.

A vitamin B deficiency can show up as:

• Increased hair loss.
• A loss of shine.
• Hair fragility.
• Slower hair growth.

Prolonged vitamin deficiencies can also weaken the hair fiber, making hair more vulnerable to external aggressions.

• Zinc: Supports cell regeneration and helps maintain balanced sebum production, essential for well-hydrated hair. Zinc also helps strengthen hair follicles.
• Iron: Supports good blood circulation and optimal oxygenation of the scalp, helping to prevent hair loss. Iron is crucial for carrying oxygen to the hair roots, thereby stimulating their growth.

Zinc-rich foods include seafood, pumpkin seeds and lentils. For iron, go for spinach, lean red meat and green vegetables.

Omega-3s are essential for curl hydration and elasticity. They help keep hair supple and reduce scalp inflammation. The best sources of omega-3 are:

• Oily fish (salmon, mackerel, sardines).
• Flaxseeds.
• Nuts.

Regular intake of omega-3 can also help prevent dry ends and split ends.

These nutrients protect the hair fiber against free radicals and strengthen the hair's structure, making it more resilient. Vitamin E is also known to improve blood circulation in the scalp.

Vitamin E is found in almonds, sunflower seeds and olive oil. Antioxidants, found in berries and colourful vegetables, are also essential for preventing hair damage.

Dietary supplements can be useful in cases of:

• Identified vitamin deficiencies.
• Periods of intense stress or fatigue.
• Difficulty getting certain nutrients from diet alone.

They help fill nutritional gaps and optimise hair health.
