What is baldness ?

Alopecia is the partial or total absence of hair in the areas of the body where it naturally grows. It may be limited to the scalp or affect the whole body, and may be temporary or permanent. Although everyone may lose hair, menare more often affected by this phenomenon.

But not all of them have this sensitivity, which explains why certain people are never concerned by this condition.

What are the most frequent causes of male hair loss ?


A family history of hair loss is the main factor in hair thinning, in particular for male baldness2.


The scalp cells in men with a genetic predisposition have a heightened reaction to the active form of testosterone, dihydrotestosterone, which causes their hair follicles to shrink and eventually stops hair growth. This is what we refer to as androgenetic alopecia, the form of alopecia most common in men3.

Stressful events

Whether it is caused by emotional or physical stress, a shock may trigger hair loss. Surgery or a death in the family are examples of such trigger events4.

Poor diet

Vitamins and oligo-elements are essential to the hair follicle cycle and maintain homeostasis as enzyme cofactors, hormones, antioxidants and immunomodulators5

Types of baldness

Several types of baldness may occur in men. These include:

  • Hereditary androgenetic alopecia: also referred to as male baldness, it is the most common form caused by a genetic sensitivity to male hormones. The gradual thinning of the capillary area follows a well-defined pattern which starts in the temporal region and extends to the crown. This alopecia affects men as they age6
  • Acute alopecia: this is due to significant stress, a medical treatment, a nutritional deficiency, illness or other. This type of alopecia results in a rapid and considerable loss of hair7
  • Congenital alopecia: this is quite rare and results in abnormal hair composition or the absence of roots8
  • Localised alopecia: this may be caused by burns, a tumour, radiotherapy or alopecia areata. It is localised and reversible9

How is it identified ?

A few external signs can put us on the right track. There are many precursor symptoms of baldness that can be seen in particular with the forehead gradually thinning, from above the temples to the crown.

Other clues can also give an indication:

  • Hair growing at unequal lengths
  • A visible scalp, with a feeling of tingling or itchiness
  • Changing hair type, becoming greasier, duller or finer
  • Quite slow hair growth
  • Hair on the pillow in the morning, or between your fingers when you run them through your hair

What should you do to have stronger, thicker hair ?
