Dull, dry and brittle hair? Hair can be quickly damaged by certain known factors such as heat, sun or unsuitable hair care. But do you know that their appearance also often reflects our physical and mental state? And yes, our hair can suffer from intense stress, fatigue or nutritional deficiencies. So if you are curious to know more about the composition of your hair, its growth or even the different ways to take care of it from the inside, you have come to the right place!

What is a hair?

Grow your hair

Like nails and body hair, hair belongs to the family of dander. A hair is a filament that forms at the top of the head whose primary function is to protect it. It mainly consists of a visible part called stem, formed of dead cells and an invisible part, called the root. The latter is actually a active growth zone hair since it is made up of living cells ! In fact, unlike the stem, it benefits from the nutrient supplies provided by the blood capillaries located above, thus allowing the hair growth.

What is the composition of the hair?

Hair composition

Regarding their structure, the hair is mainly composed of a protein fibrous: the keratin who assures stiffness and strength to the whole structure. In less quantity we also findwater and sebum, a greasy film that comes from the nearby sebaceous glands. Finally is present from the melanin which is the pigment responsible for the natural color of your hair.

Did you know?

With age, the psebum odor decreases causing drying of the scalp.

How does our hair grow?

Grow your hair naturally

Our hair (unfortunately for us) has a limited lifespan. They each follow a “life cycle” alternating between growth, fall and regrowth corresponding to the following phases:

- The anagen phase (active growth phase): the cells at the root level divide quickly, promoting hair growth.

- The catagen phase (transition phase): the duration of this phase is relatively short (generally less than a month). Here, the hair growth speed is slowed down.

- The telogen phase: the hair is dead but remains on the head until the new underlying root is strong enough to dislodge it.

- The fall phase: the old hair falls out but a new hair is ready to replace it!

Do not panic, fortunately, each hair progresses at a different stage! It is therefore normal to lose some of your hair every day.

Did you know?

Hair on the scalp grows on average 0,35mm per day!

What are the nutrients to promote for healthy hair?

Our diet is directly related to the health of our hair, and therefore to its growth. Indeed, like all the organs of our body our hair has specific macronutrient needss (proteins, lipids, carbohydrates) and micronutrients (vitamins, minerals and trace elements). So here is a little zoom on the nutrients to favor for guaranteed hair growth !


Foods to grow hair

A protein is a whole amino acids. To synthesize your own proteins such as keratin, the body therefore needs a supply of amino acids via food. These are provided by our food when we consume foods containing proteins animals ou vegetable.

- protein sources of animal origin are meats, fish, eggs, dairy products and original protein sources vegetable are cereals (wheat, rice, barley, corn, etc.) and derivatives (potatoes, sweet potatoes, etc.), legumes (lentils, soybeans, beans, etc.) and oilseeds (almonds, nuts, hazelnuts, etc.).


Zinc for hair

Le zinc is a trace element essential to keep your hair healthy! Indeed, it cleanses the scalp fighting against cell aging thanks to its action antioxidant et anti-inflammatory. He also participates in the keratin synthesis thus restoring imbalances and densify the capillary mass.

Zinc is mainly found in seafood, fish, meat and oilseeds.

The iron

Iron and hair loss

The main role of iron is to fix oxygen on a protein called hemoglobin, which is part of the composition of Red cells. These allow the oxygen transport in the blood andoxygenation of all the cells in the body. Thus, a deficiency in this mineral helps to accelerate the cell aging of our body and therefore of our hair!

The main sources of iron are organ meats, red meat, fish, seafood, whole grains, legumes, cocoa and sesame.

Vitamin C

Vitamin C protect hair

Let’s also think about the vitamin C ! This vitamin acts as a antioxidant here protects our hair and prevents them from falling. If you are a smoker or a sportsperson, know that your needs are increased due to the massive intake of free radicals brought by the combustion of tobacco or energy expenditure!

As vitamin C is very sensitive to heat and light, it is mainly found in raw fruits and vegetables and especially in kiwis, citrus fruits, peppers and parsley!

B vitamins

biotin and hair

The vitamins of group B are the vitamins of the hair par excellence and in particular the vitamin B8 (biotin) and the vitamins B1, B3, B5 and B6. Indeed, they generally contribute to the cell regeneration ensuring optimal hair growth. Also, these vitamins help regulate sebum secretion close to the scalp and stimulate blood circulation at the roots. Biotin would also be necessary for the synthesis of keratin.

The vitamins in this group are easy to find in our diet because they are present in most foods. However, in the event of an unbalanced diet or an increase in needs (during pregnancy, if you are athletic or if you suffer from chronic illness for example), deficits may appear.

What to think of food supplements for hair?

Food supplements for hair

For various reasons (smoking, seasonal changes, stress, poor eating habits, etc.) nutritional deficiencies can arise and alter the quality of our hair. Sometimes taking a dietary supplement can offer a little help halt their fall et densify the capillary mass. But how do you choose and use them well?


Prefer food supplements composed of several nutrients

A food supplement that provides only a vitamin or a mineral will be much less effective than a food supplement made up of several elements because the nutrients act all in synergy the ones with the others. Also, prefer nutritional supplements with a high nutritional density especially in group B vitamins especially in biotin (vitamin B8), vitamin C, to promote the absorption of iron and zinc to limit the cellular aging of your hair.

Prefer dietary supplements for hair made in France

Choosing food supplements made in France is a preferred criterion to guarantee safety and full traceability on the supplements you consume. Indeed, any supplement made in France must follow the French legislation in force in terms of hygiene and be in good standing with the DDPP (Departmental Directorate for the Protection of Populations, formerly DGCCRF). Thus, favoring food supplements made in France guarantees you greater transparency et health security.

Plan a cure of about three months for more effectiveness

Even if effects may appear as soon as three weeks (less brittle hair, improved quality…) the complete results for healthy hair are generally visible after a cure of about three months.

Testing food supplements

The many opinions that you will find on the internet or with those around you concerning food supplements may allow you to make an opinion on the effectiveness of the product. However, remember that each body is different and certain dietary supplements will work on a person but not necessarily on you. The best option is still to test to make your own opinion!
