The Hair Summum Concept
Hair density in men

THE RESPONSIBLE FACTORS:
MICROCIRCULATION
Keratin is synthesized from blood components in the hair follicle. This molecule is created from amino acids, vitamins, and energy from the oxygen carried by red blood cells. The growth and vitality of the hair are linked to the microcirculation of blood in the hair follicle. Microcirculation and hair density vary depending on the area of the scalp.
TESTOSTERONE? DIHYDROTESTOSTERONE (DHT)?
Testosterone is presented in scientific circles as being responsible for alopecia and hair loss. It is observed that men with low hair density, especially on the top of the head, have a thick and abundant beard. Testosterone present in the blood irrigates the beard and scalp equally. Therefore, the regression of hair due to testosterone should be accompanied by a regression of the beard. In addition, after the age of 30, the testosterone level in the blood decreases regularly due to the slowdown in the production of male hormones (testosterone) by the sex glands. As a result, the decrease in testosterone levels with age should lead to the regrowth or maintenance of hair density.
Hair density and testosterone

80% of men (caucasian) are affected by androgenic alopecia*
If testosterone (androgen hormone) were the only cause of androgenetic alopecia, bald men should not have beards.

Testosterone levels begin to decline after the age of 30.
If testosterone were responsible for hair loss, hair should regrow with age.

Hair loss affects the areas where the microcirculation decreases.

Hair density in women

Hair loss or alopecia manifests itself in a very different way in women than in men. While hair may become lighter, thinner, and sparser with age, especially after menopause, it does not disappear, leaving visible baldness like in men.
About 20% of women around the age of 40 are prone to hair loss, then 25% after the age of 60, increasing thereafter.

MICROCIRCULATION
The keratin of the hair is formed in the sebaceous follicle, more precisely in the keratinocytes, cells irrigated by the microcirculation. From the age of 20, this microcirculation decreases, and after 40, the hormonal changes associated with menopause disrupt the balance, weakening the hair.
