What are the causes of hair loss?

Seasonal changes, stress of daily life, unsuitable cosmetics, repeated blow-drying and coloring, hormonal disturbances.

 

Our hair undergoes daily attacks which weaken and thin it so that it eventually falls out.


Obviously, it is not only about these factors, there are others such as the diet which nowadays is impoverished and no longer provides in quantity the nutrients necessary for the construction of the hair fiber.


Find out in this article how to prevent hair loss with a suitable diet and hair food supplement .

I. The composition of hair

Hair is composed of 95% keratin.

This keratin is a so-called “fibrous” protein, that is to say a protein which plays a structural role: it enters into the composition of the tissues of the organism and serves as a basis for the production of enzymes or hormones. Its main role is a protective role.


Keratin is composed of B vitamins, trace elements, minerals and sulfur amino acids.


Vitamin B5 limits hair loss, accelerates growth and acts on the protection of cells, vitamin B9 acts on cell repair and vitamin B8 stimulates hair growth.


Zinc protects against oxidative stress, iron transports oxygen to cells just like magnesium.


It is essential to stimulate the blood microcirculation of the scalp in order to provide the hair bulb with all the nutrients necessary for good hair health.


Finally, methionine fights against the aging of the body, it strengthens the hair because it contains sulfur, an essential element for keratin.


The action of cystine is coupled to that of zinc, it contributes to the synthesis of proteins and collagen. It helps absorb calcium, one of the factors required to form collagen and lysine stimulates hair growth.


In short, these are nutrients that you can find in food and which are part of the composition of hair. When the supply is insufficient, when you have vitamin deficiencies responsible for hair loss, your hair is weakened, you can observe a loss of shine and a loss of mass strong>.


II. Causes of hair loss

Hair loss is not always linked to diet, in fact, nowadays we suffer many daily attacks.


stress and hormonal imbalances have their share of culpability. cortisol is the stress hormone, it is triggered when we are subjected to daily constraints.


Its role is to help us prepare to deal with the stress experienced. However, when stress is too great and constant, it can become chronic and its rate remains too high.


Its secretion causes the retraction of the hair follicles and blood vessels, the hair fiber is no longer irrigated correctly, the nutrients are therefore no longer provided in sufficient quantity andthe hair becomes thin, fragile and ultimately, it ends up fall. 

1. Genetic pathologies

Then, we are not all equal, genetics has its little say.

There are genetic pathologies such as alopecia for example. It is observed more in men than in women.

It is in fact an excess of male hormones: testosterone, which accelerates hair growth and modifies the hair cycle which occurs in three phases.


The first phase is the Anagen phase, a growth phase for a period that can extend over 2 to 5 years. Then, with age this phase becomes shorter and shorter.


The second phase is the so-called Catagen phase. It only affects 3% of our hair and is considered a “sleep” phase since the hair no longer grows. It nevertheless remains attached to the hair follicle.


The third and final phase is the Telogen phase. It is a resting phase, it concerns 12% of the hair. The hair does not grow, it remains attached to its follicle for a period of 6 to 7 months until it eventually falls out and gives way to the creation of a new hair.

In the case of alopecia, the bulb tires more quickly and ends up atrophying and creating areas of fine hair where there are fewer of them. Once the hair dies, “empty” areas can be observed.

2. Hormonal imbalance and impact on hair

a. Cause in humans

In men, hair loss is often linked to an excess of dihydrotestosterone (DHT), a derivative of testosterone. 

This hormone causes hair follicles to miniaturize, making hair thinner and more fragile until it eventually falls out.


Other factors influencing hair loss in men

Besides excess dihydrotestosterone (DHT), several other factors can contribute to hair loss in men. 


Chronic stress, for example, can cause excessive secretion of cortisol, a hormone that disrupts the hair cycle and weakens hair follicles. 


Likewise, a diet deficient in essential nutrients such as B vitamins, zinc and iron can weaken hair and accelerate its loss. Lifestyle habits, such as smoking and excessive alcohol consumption, can also have a negative impact on hair health. 


Finally, using harsh or unsuitable hair products can damage the scalp and hair, increasing the risk of hair loss. By taking care of your lifestyle and choosing quality hair products, it is possible to minimize these factors and preserve hair health.


b. Cause in women

In women, hormonal fluctuations are often responsible for hair loss. 

The menstrual cycles, pregnancy, childbirth, breastfeeding and menopause are periods when hormone levels can vary considerably, thus affecting hair health.


Hormonal fluctuations and their impact on women's hair

Hormonal fluctuations play a crucial role in hair loss in women. 

Significant hormonal changes, such as those observed during pregnancy, childbirth, menopause or even menstrual cycles, can alter hair health. 


For example, during pregnancy, high estrogen levels prolong the hair growth phase, but after childbirth, the sudden drop in hormonal levels can lead to significant hair loss. 


Additionally, medical conditions such as polycystic ovary syndrome (PCOS) or thyroid disorders can also disrupt hormonal balance and cause diffuse hair loss. 

A balanced diet and the use of appropriate dietary supplements can help maintain stable hormonal levels and promote hair health.


c. In young women: causes

Young women may also be affected by hair loss due to hormonal imbalances, often caused by oral contraceptives, thyroid disorders or syndromes like polycystic ovary syndrome (PCOS).


d. Estrogen and hair

Estrogens play a key role in regulating the life cycle of hair. 

By prolonging the anagen phase, which is the phase of active hair growth, they promote thicker and more voluminous hair. 

When there is a significant decrease in estrogen levels, as is often the case after menopause or following hormonal treatments, hair can enter the telogen phase prematurely, leading to increased shedding. 

This hormonal drop can also thin the hair structure, making it more fragile and susceptible to breakage. Maintaining optimal hormonal balance is therefore essential to preserve hair density and health.


e. Progesterone and hair growth

Progesterone, a key hormone in the menstrual cycle, plays an essential role in hair health. 

It helps balance the effects of dihydrotestosterone (DHT), a hormone that can cause hair loss by miniaturizing hair follicles. 

By counteracting this effect, progesterone promotes an environment conducive to hair growth. 

However, significant fluctuations in this hormone can unbalance the hair cycle, leading to temporary but significant hair loss. 

These variations are common during pregnancy, after childbirth or during premenopause, times when progesterone levels can be particularly unstable. 

Maintaining optimal hormonal balance through a suitable diet and specific nutritional supplements can help minimize these effects and support continued hair growth.

Bring seasonal fruits and vegetables, foods rich in vitamins and minerals for a colorful plate!

We also recommend that you consume good fatty acids, rich in essential omegas, that is to say, which are not produced by the body but which must be supplied through food.


Oil seeds such as walnuts, hazelnuts and almonds, vegetable oils and fatty fish are rich in omega 3 and 6. They have many antioxidant and cholesterol-lowering properties, for example. . You can provide vegetable or animal proteins for their quantity of amino acids.
