Changes in hair properties are often used as indicators of exposure to environmental factors or certain diseases.
A scientific study shows that the increase in hair fragility is associated with a high rate of glycation and aging.
A Japanese team (1) managed to establish the following double link:
– The glycation of the hair reduces their content of capillary proteins (keratin).
– The glycation of hair reduces their resistance to breakage.
This double phenomenon is also correlated with age. And logically, hair glycation is higher in the tips of the hair than near the root.
In an unexplained way, hair care treatments such as hair dye increase / reinforce these effects.
Subject to further studies, hair fragility, easily identifiable (thin, brittle, dull), could be used as a relevant marker of aging. Its improvement would then be a good indicator of effective anti-aging management.
