B/A PRODUCT CAROUSEL
BEFORE / AFTER
Illustration of the contemplated results obtained after applying:
Continuous exposure to daily environmental and mechanical aggressions leads to a progressive ageing of the hair fiber, consequently contributing to an overall aged appearance. Given that hair, akin to skin, serves as a prominent visual indicator of age, its compromised condition can significantly impact an individual's self-perception and confidence.
To address these concerns, Kérastase has identified 5 signs of hair ageing - frizz, dullness, lack of thickness, lack of volume and developed a targeted regimen, including an innovative night serum, designed to visibly improve these signs.
