Hair vitality depends on a subtle balance between genetics, environment, and nutrition. Among the determining factors, the intake of vitamins and nutrients plays a central role.
A varied diet and targeted intake of micronutrients help preserve hair density, shine, and strength while limiting hair loss.
Women and men who want to regain radiant hair often choose to combine appropriate nutritional actions with specific natural solutions.
Vitamin D deficiency
Vitamin D plays a crucial role in hair loss. A deficiency in vitamin D therefore leads to hair loss and dull hair. When vitamin D is lacking, hair follicles weaken and hair no longer regrows.
Furthermore, a study showed that lack of vitamin D also leads to an increase in the amount of sebum on the scalp. A real vicious circle, because the greasier our hair is, the more we wash it, which results in drying and straightening afterward, thus weakening the hair and eventually causing it to fall out.
Iron deficiency
Iron deficiency is one of the most common deficiencies! Pregnant women, the elderly, vegans, and vegetarians are at increased risk of iron deficiency.
One consequence of this deficiency is hair loss. Iron plays a crucial role in blood formation and hair has a high blood demand; if it doesn't receive enough, it begins to fall out.
Zinc deficiency
Zinc acts on the hair, it strengthens the synthesis of keratin and collagen by making hair silkier and prevents thinning. A deficiency in zinc can manifest as alopecia and hair aging.
Vitamin B deficiency
B vitamins are essential to strengthen the hair and help maintain healthy hair. Indeed, they stimulate the production of Keratin, the protein that forms hair and nails.
II. Understanding and preventing hair loss
Hair loss can be reactive (stress, fatigue, postpartum) or progressive (hormonal imbalance, deficiencies).
A deficiency in vitamins B, D, iron, or zinc disrupts the hair cycle and weakens the fiber. An optimal intake of vitamins for hair helps support growth and maintain hair density.
Common signs of deficiencies:
Certain nutritional deficiencies directly impact the quality of the hair fiber.
Identifying these signs allows for quick action with targeted hair vitamins:
Diffuse or patchy hair loss
Dull, brittle, or thinning hair
Slow or stagnant growth
Soft, ridged, or brittle nails
These signals often reveal a deficiency in biotin (vitamin B8), iron, zinc, or vitamins D and C, essential for hair growth and strength.
III. Nutrition at the service of your hair
Superfoods rich in nutrients for healthy hair
Some foods, called superfoods, are particularly rich in essential nutrients for hair health. For example, spinach, which contains a lot of iron, vitamin C, and beta-carotene, helps improve scalp blood circulation and participates in collagen formation. Fatty fish like trout, rich in omega-3 and vitamin D, help keep hair supple and well hydrated. Oats, thanks to their content of B vitamins, iron, and zinc, deeply nourish the scalp. Finally, eggs provide good quality proteins and are easy to include in the daily diet.
- Spinach is rich in iron, vitamin C, and beta-carotene, essential for hair vitality.
- Fatty fish provide omega-3 and vitamin D, promoting shine and hydration.
- Oats contain B vitamins, iron, and zinc to nourish the scalp and strengthen the fiber.
- Eggs provide complete proteins and B vitamins to support hair structure.
Flax and sunflower seeds are a source of essential fatty acids
Red fruits are known for their high antioxidant content.

How can vitamins improve the health of your hair?
Vitamins play a fundamental role in hair health. They act on several levels: by stimulating keratin production, promoting scalp microcirculation, protecting cells against oxidative stress, and maintaining fiber hydration. An optimal intake of vitamins results in stronger, shinier hair that is less prone to breakage and loss. Vitamins B, D, C, and E, combined with minerals like iron and zinc, contribute to visibly healthier and more radiant hair.
What are the essential vitamins for radiant hair?
To preserve the shine and vitality of hair, several vitamins are essential: B vitamins (notably B8, B5, and B12), vitamin D, vitamin C which contributes to collagen production, as well as vitamin E, known for its antioxidant properties. These vitamins work synergistically to support growth, strengthen the fiber, and protect hair from external aggressions.
Which vitamin deficiency causes hair loss?
A deficiency in B vitamins, especially biotin (B8), or vitamin D, can result in more pronounced hair loss. Lack of iron or zinc also exacerbates this phenomenon. These deficiencies weaken the hair structure and disrupt the growth cycle, promoting premature hair loss.
What is the most effective vitamin for hair?
Biotin, or vitamin B8, is among the most recognized vitamins for its effectiveness on hair health. It helps strengthen the fiber, stimulate growth, and limit breakage. However, a comprehensive approach combining several vitamins and minerals proves most relevant to achieve visible results.
Which vitamin stimulates hair growth?
Vitamin B8 (biotin) and vitamin D are particularly involved in stimulating hair growth. They support cell renewal and the proper functioning of hair follicles, thus promoting denser and stronger hair.
Which dietary supplements provide the necessary elements to strengthen hair?

How can the necessary nutrients for hair health be incorporated into the daily diet?
Adopting a varied diet rich in fresh foods is the first step to support the health of hair and nails. Favor sources of protein (eggs, legumes, fish), green vegetables, red fruits, seeds, and nuts. Vegetable oils (walnut, rapeseed, flax) provide essential fatty acids. Additionally, dedicated dietary supplements allow for precise doses of nutrients, especially during periods of stress, fatigue, or seasonal changes.
Can hair loss be prevented through sufficient vitamin intake?
A sufficient and regular intake of vitamins and minerals helps prevent hair loss. Essential nutrients contribute to maintaining the growth cycle, fiber strength, and scalp health. A balanced diet, supplemented by appropriate formulas, limits the risk of excessive hair loss.
How do vitamins act on the scalp and hair follicles to promote growth?
Vitamins provide hair follicles with the elements necessary for their cellular renewal. They participate in keratin synthesis, scalp microcirculation, and protection against oxidative stress. Vitamins B, D, C, and E, combined with zinc and iron, promote an environment conducive to hair growth and strength.
What is the importance of nutrients in combating dryness, breakage, or loss of shine?
Nutrients, particularly essential vitamins, act on the very structure of the hair. They improve hydration, reduce breakage, and restore shine. Hair that is sufficiently nourished, both inside and out, better resists damage, maintains its suppleness, and its natural glow.
