We're used to hearing about the aging of skin (or cutaneous aging), but hair aging
is significantly less talked about. However, if we fully understand that facial skin is affected by time, then why would it be any different for the scalp and hair? There are several warning signs.
Firstly, the appearance of gray and white hair; these small hairs which irritate men and women when they look in the mirror. It is one of the first signs of hair aging. Like all cells in the human body, the activity of melanocytes decreases over time. These cells, located at the hair root, are more or less full of pigment (called melanin), which allows them to add color to hair (this can be either dark or light). When the melanocytes slow down and then stop the production of melanin, white hair begins to grow. This often occurs from the ages of 45-50, however this is not the case universally. Depending on the person, it can happen much earlier.
Flat and thin hair that is difficult to style
The scalp's ecosystem eventually deteriorates: as micro-circulation is no longer sufficiently stimulated, blood flow in the hair root is limited. Less oxygen and nutrients (vitamins and trace elements) necessary for a good hair growth rate
are supplied. The sebaceous glands produce less sebum, the natural oily film which helps to hydrate and protect the scalp and hair. Result: hair becomes thinner, dry and dull, loses volume and grows more slowly. This is the beginning of thin and flat hair that is more difficult to style.
