Hair loss, if caused by a shortening of the hair cycle, can lead to premature hair loss and baldness.

In this case, it is called progressive hair loss because it sets in gradually.

What do we mean by baldness? Men can suffer from baldness, otherwise known as androgenetic alopecia. In this case, certain areas of the scalp become bald first: the temples and crown of the head.

Hair loss progresses in spurts.

Nearly 1 out of 3 men see the first signs of hair loss at the age of 30.

When it is progressive, hair loss in women is linked to an imbalance of male hormones. Contrary totheir name, these hormones are also present in women, who can also suffer from this type of hair loss.

Women's hair is essentially weakened at the top and along the parting. The hair becomes thinner and more and more sparse.

51% of women say they are embarrassed by hair loss.

Recognize your hair loss type

In everyday speech, we often hear the term " hair loss " used as a generic term.

" I'm losing my hair in handfuls. "


However, there are two types of hair loss that you must know how to distinguish:

  • reactive hair loss;
  • progressive hair loss.

They do not have the same causes and, therefore, are not treated in the same way.

As opposed to reactionary hair loss which, as its name indicates, occurs on a one-time basis in response to an event, progressive hair loss sets in over several months and can lead to baldness.

This baldness, also called androgenetic alopecia or androgenic alopecia, is characterized by a progressive and more or less localized decrease in hair, giving the appearance of a less dense hair mass.

What are the causes of baldness due to progressive hair loss?

The growth phase is shortened

Progressive hair loss corresponds to a shortening of the growth phase of the hair (the anagen phase) which is linked to a progressive degeneration of the hair follicle.

To understand this phenomenon, it is important to briefly recall how the life cycle of a hair unfolds.

As we all know, our hair is constantly being renewed.


A hair appears, grows, then dies. And then the hair falls out.

This hair cycle lasts on average 3 years for a man and 5 years for a woman. What is less commonly known is that this cycle is repeated only 25 times. If these cycles keep a regular rhythm, we are supposed to have a "normal" amount of hair throughout our lives.

But, in the case of progressive hair loss, this rhythm is accelerated. Cycles become shorter and shorter, at the risk of coming to an early end.

In fact, once it has reached exhaustion, at the end of the 25 cycles, the hair follicle dies. It resorbs and then disappears.

At this stage, only surgery can provide a solution, a hair transplant, for example. It is therefore important to take alopecia seriously as soon as possible: when there is still time to re-grow hair.

Why does the rhythm of the hair cycles go so fast?

Progressive hair loss is the result of a dysfunction, often genetic, of the hair and scalp in response to certain male hormones: androgens. This dependency on hormones also explains why this phenomenon only begins after puberty.

Testosterone is involved, but indirectly.

To cause hair loss, testosterone must first be converted by 5α-reductase to dihydrotestosterone (DHT).
Hyperactivity of this enzyme leads to an overproduction of DHT, which will cause a shortening of the hair's life cycle and, therefore, an acceleration of the hair's cycles


The period of hair production is shortened, the cycles follow each other more quickly, the hair becomes thinner, the follicle becomes miniaturized and exhausted before dying and disappearing.

As a result, the succession of the 25 hair cycles, which was supposed to last a lifetime, ends earlier than expected and can give way to partial baldness, especially at the top of the head, or total baldness.

The other negative effect of DHT is that it will also harm the environment around the hair. In particular, it stimulates the sebaceous glands which will increase sebum production.

When combined, these two phenomena will cause weakened hair to fall out before it reaches its maximum length. They then give way to new growth which will also have a shortened life span. The hair grows back thinner and shorter.

The fight against baldness must be taken care of as soon as possible

To combat this premature hair loss, it is important to prolong the life of the hair by intervening, understandably, before the hair cycles are exhausted once and for all.

The best approach is to prevent hair loss by maintaining and prolonging the anagen phase while stopping the snowballing hair cycles.


In order to respect the sensitivity of the scalp, and its health in general, it is important to favor treatments based on natural active ingredients such as essential oils and plant extracts.

The naturalness of these products guarantees both optimal efficiency and that your scalp will not react badly.
