Blonde Guard is a leave-in from the Kérastase Blond Absolu range made for every kind of blonde, from balayage and highlights to full lightening. The fine milky formula sinks straight into the hair, leaving it softer, easier to detangle and properly hydrated.

Hyaluronic acid in two molecular sizes draws moisture deep into the fibre and helps hold it there, while vitamins C and E add antioxidant care to keep blonde looking bright and fresh.

It works as an everyday shield against the things that dull blonde fastest: heat styling, sun, pool chlorine, salt water and dryness. Pair it with Bain Lumière and Cicaflash for the full Blond Absolu routine.

Shampoo and condition, then towel dry. Spray evenly through lengths and ends, comb through and style as usual. Do not rinse.
