REVERSE 5 SIGNS OF AGING
Just like our skin, hair undergoes a complex aging process. Kérastase's research dives deep into the "invisible root causes" of hair aging, identifying several critical factors: epigenetic changes, DNA instability, cellular communication breakdown, stem cell exhaustion, chronic micro-inflammation, cell senescence, microbiome alterations, mitochondrial dysfunction, and loss of proteostasis.
These internal processes manifest as the more familiar "5 signs of hair aging":
DRYNESS
DULLNESS
FRIZZ
LACK OF VOLUME
THINNING
The Chronologiste philosophy recognizes that to truly combat these visible signs, we must address their biological origins.
