Similarly, as the hair ages, root hair cells’ telomers become shorter.
Every hair is lost and produced, undergoing a different stage of the growth cycle of follicles: growing, degeneration and resting.
After repeating the growth cycle an average of 20 to 25 times throughout the lifetime, all the telomeres become exhausted and hair follicles stop their growth cycle.

Telomerase is an enzyme that prevents telomeres attached to the ends of chromosomes from becoming shorter and helps them longer.
Activating this enzyme can contribute to delaying the aging and extend lifespan.
If telomeres can be prevented from becoming shorter and being exhausted, aging-induced hair loss can be solved.
Even those who do not have baldness genes end up losing some of their hairs and hair follicles shrink as they get older.
As a result, thick hairs and thin hairs get mixed, resulting in making the hair look thinner.
In addition, the number of hair follicles is reduced, which causes age-induced baldness to be observed over the entire scalp.
