A heat-protecting serum that smooths and seals fragile, bleached lengths
Kérastase Blond Absolu Cicaplasme Hair Primer is a fortifying, heat-protecting serum for lightened, highlighted or bleached hair. Blonde hair is often more fragile, and this primer strengthens it and shields it from styling tools up to 230°C (446°F). It also helps seal and unify split ends, so lengths look smoother and healthier. Hyaluronic acid helps fill in damaged areas of the fibre, while edelweiss flower extract brings antioxidant protection.
The texture
A light, creamy serum that you pump onto damp lengths. It spreads easily, does not weigh blonde hair down and leaves it soft, smooth and shiny with the classic Kérastase scent.
Who it suits
- Bleached, highlighted or lightened hair
- Blondes who blow-dry, straighten or curl often
- Ends prone to splitting and frizz
- Anyone who wants a leave-in that protects and smooths at once
Worth knowing before you buy: It contains silicones (amodimethicone), fragrance and a small amount of violet dye. Very fine hair can look weighed down if you use more than two pumps, so start small.
How long one bottle lasts
Using two to four pumps several times a week, the 150ml bottle lasts around three to four months.
