Hair is a direct reflection of the quality and balance of our diet.
Several micronutrients are essential for good hair health: minerals, amino acids, vitamins, etc. In this article we detail the role of vitamins on the vitality and resistance of our hair.
Biotin, for healthy hair
Also called vitamin B8 or vitamin H, biotin is an essential nutrient for good hair health.
What are the benefits and role of vitamin B8?
Biotin plays a key role in many metabolisms such as the synthesis of amino acids and the degradation of proteins. It is also involved in the normal functioning of the nervous system.
Vitamin H is therefore an essential element for the good health of our body. It is just as much when it comes to hair. Indeed, vitamin H is involved in:
- Hair renewal by stimulating regrowth;
- Stimulation of keratin synthesis . This protein is the main constituent of hair and nails;
- Protection against dryness of the scalp : by preventing the scalp from losing its elasticity, biotin prevents hair breakage;
- The synthesis of certain vitamins : biotin indirectly promotes hair regeneration. Indeed, it acts as a coenzyme in the synthesis of vitamins B9 and B12. These are essential for the good health of the hair.
Thanks to all its properties, biotin is often recommended to limit hair loss and influence regrowth. The benefits of vitamin B8 on hair are recognized by European health authorities.
What are the symptoms of biotin deficiency?
Different symptoms can alert you to a possible mild biotin deficiency :
- Hair that becomes brittle, fragile, even greasy;
- Daily hair loss that exceeds the normal threshold of 100 hairs;
- Dry skin and scalp;
- The appearance of acne or erythema;
- Brittle and fragile nails;
Taking medications, poor lifestyle, an unbalanced diet, pregnancy or health problems can cause biotin deficiency.
B group vitamins essential for your hair
Biotin isn't the only thing that affects the health of your hair . Most B vitamins also contribute to the good health of your hair.
Vitamin B5 is also called pantothenic acid. This micronutrient is often recommended in combination with biotin to regain healthy hair.
Pantothenic acid would indeed have a beneficial action on the cells of the hair follicle, the hair root. In fact, B5 helps to slow down hair loss.
Also called folic acid, vitamin B9 stimulates cellular regeneration of tissues and hair follicles.
More hair loss than usual may be a sign of folic acid deficiency. This is accompanied by a change in the appearance of the hair which appears duller and more brittle.
Vitamin B12 or cobalamin is the largest vitamin in the B group. Water-soluble, it does not play a role in the health of the hair, but in its coloring.
Indeed, one of the symptoms of a vitamin B12 deficiency is a reduced production of melanin, this natural pigment which gives color to your hair. A balanced diet of cobalamin slows the risk of cellular aging, and therefore helps to slow down the appearance of white hair.
The benefits of vitamin B1 on hair have not yet been demonstrated. However, thiamine is essential for the normal functioning of our body.
Vitamin B3 or PP contributes to the synthesis of keratin and to fight against oxidative stress. The latter is the cause of cellular degeneration, particularly of scalp cells. A vitamin B3 deficiency also results in an early appearance of white hair.
Vitamin B6 does not directly contribute to the good health of hair. On the other hand, it comes into play in numerous metabolic mechanisms which go in this direction.
How to cover your daily needs for healthy hair?
The human body only synthesizes a very limited number of vitamins. This is the case for vitamin D through the epidermis or B3. The intestinal flora synthesizes B1, B2 and B8.
However, this synthesis is often insufficient. The main source of vitamins and biotin is found on our plate. In theory, a healthy and balanced diet allows us to meet our daily needs at any age.
In reality, it is quite different. Many French people have deficiencies. These are often linked to taking medications, a sedentary lifestyle or even the consumption of ultra-processed foods.
To avoid a deficiency and have healthy hair , taking food supplements rich in biotin and B vitamins may be necessary. For this, our Vegetable Biotin formula concentrates the most active nutrients for the health of your hair.
