Hair loss for men

Hair loss is a natural phenomenon in all men. The life cycle of the hair shows very clearly that each hair follicle expels the hair at its telogen phase and then starts the process of growth from the root. On the other side, abnormal hair loss is a real problem that must be treated.

Hair loss problems can make man head completely bald. Few men know, but there are solutions to correct the situation. It is recommended to prevent a significant hair loss by reacting quickly.

Although a large portion of men give the impression that they do not have to take care of their hair, it becomes often different when an abnormal hair loss happens.

As in women, the most common type of abnormal hair loss in men is known under the name of androgenetic alopecia.

How to identify an abnormal loss?

  • From adolescence if the number of hair fall is more than 100 per day
  • If there are more bald areas of the scalp or if the hair growth phase does not start.
  • If the density of hair becomes less important

How is abnormal hair loss

You should know that if you are a man that lose his hair, you have almost 95% chance to follow the evolutionary cycle proposed by Hamilton (reworked by Norwood). It includes seven specific stages of thinning hair. These stages, which gradually leads to baldness are:

Baldness level 1 Baldness level 2 Baldness level 3 Baldness level 4
Baldness level 5 Baldness level 6 Baldness level 7 Baldness level 8

Stages 1 and 2: hair loss begins on the frontal area (level gulfs) by displaying some balding areas on the temples
Stage 3: Hair loss is now considered important enough for it to be called "baldness"
Stage 4: The vertex (top of head) is then affected, initiating a "tonsure"
Stage 5: The portion of the overhead is greatly affected, the "tonsure" is more complete
Stage 6: Only a thin filament of hair is visible between the tonsure and the frontal area
Stage 7: Hair loss extends across the top of the head, leaving only a ring (high)
Photo 8 (7a) This is not a stage defined by Hamilton or Norwood but is an advanced situation of stage 7. The density of the crown narrows down a lot more.

Causes of hair loss in the man life cycle

Baby (0-2 years)

Male baby and shampoo

At birth, the production of hair is in the growth phase. At this point, it is quite normal that some areas of the scalp are not covered. At its debut, the baby's body must adapt by producing different hormones. But the production of these hormones decreases after a few days or weeks, which can cause temporary hair loss.

Boy (2-10 years)

It rather uncommon to observe cases of abnormal and persistent hair loss in the boy compared to what can be seen in men at the teenager or adult steps. The majority of alopecia in boy are related to mania, diseases or viruses caught through contact with other children. The daycare and school are venues for the spread of disease and the scalp is not spared.

When a boy lose his hair over a long period, it is important to make some verification:

• Does alopecia affect several family members (family history)?
• Does the hair loss is continuous or does it occur during specific periods or events?
• Does the hair fall out gradually or in group?
• Does the boy had an operation, illness or a major emotional shock

The main causes of hair loss in the boy:

Ringworm of the scalp

The main cause of localized alopecia in the boy is ringworm. This infection of the hair, which can also affect body hair, is the result of a fungal infection caused by dermatophytes, or microscopic fungi that feed on keratin. It is identifiable by the appearance of red round plates and a crust that looks gray on the surface of the scalp.

Alopecia areata

Alopecia areata plates are similar to those of ringworm in the form. They both looks round. The difference is in the texture of the surface that has a completely smooth appearance without peeling.

The latter is not an infection but rather a behavioral of the boy. It is characterized by a pulling hair compulsively. This disorder is mainly attributed to the child or young teenager.


Male teenager with long hair

This period in the life of a man is probably the one with the most changes for the body as for the hair. In fact, during adolescence, sex hormones or androgens, reach their maximum in order to transform the young man. As the production of androgen hormones raise, the risk of hair loss also raise. It is important to take and maintain good eating habits and personal hygiene to minimize hair loss.

Adult man

The abnormal hair loss in men are usually identified between 18 and 45 years. Indeed, in the cycle of a man's life, it is during this age that many changes and stress are experienced. It is mainly due to the transition to adulthood and the additional responsibilities that comes with it. It is often at this age that the overall health of men tends to be poorer, mainly because of the lack of physical activity and poor eating habits. When the overall level of health of the body is low, the level of testosterone decreases exponentially, which can increase the risk of hair loss.

Between 20% and 35% of men of 30 years or less are affected by androgenic hair loss.

Aging or mature man

The vast majority of men of 50 years or less, which is between 50% and 60%  are victims of a form of androgenetic alopecia . With age, this proportion increases to reach nearly 75% past 80 years.

In addition, a certain proportion of men aged between 45 and 60 years will experience another condition known as andropause, which increases the risk of damage to healthy hair and could possibly result in an abnormal loss. Andropause is characterized by a level of testosterone production at its lowest. This hormonal imbalance in men regularly causes significant hair loss.

Aggravating factors of hair loss in men

Besides hereditary predisposition, hair loss in men can appear for all kind of reasons. These are not necessarily directly responsible for hair loss, but they are among the factors aggravating the various forms of alopecia in men.


It's a fact, a good nutrition not only helps to keep a slim body, but also to keep the hair on the head. Indeed, many problems of hair loss in men are partly due to a dietary deficiency, lack of vitamins or just an excess of fatty food.

Stress an exhaustion

Whatever they may say, men also experience different kinds of stress and fatigue that can affect their health and therefore their scalp. Unlike women, men are more likely to deny stressful situations. Additionally, studies have shown that men released twice more stress hormones than women of the same age when they face acute stress situations.

Stress at work and in activities

The man is more likely to face competitiveness situations. More often than not, the pressure for performance increases the production of stress hormones in the men.

Alcohol Consumption

In Quebec, men consume more alcohol per week than women. In addition, there are more men than women with a high consumption of alcohol on a regular basis. Éduc'alcool recommends a maximum of 3 consumptions per day and 15 per week for a men.

Alcohol consumption by man and hair loss

The abuse of alcohol has a negative effect on the vitamins necessary for hair growth. Furthermore, maltose beer has a high glycemic index, which tends to increase insulin, which releases androgen, partly responsible for the loss of hair.
