Salon-Fresh Blonde. Wherever Life Takes You.
Your colour works hard to look this good. Blonde Guard Hydrating Wonder Shield works harder to keep it that way.
This cult Kérastase leave-in — now in a brilliant 45ml travel size — is everything your blonde needs to stay bright, soft and protected between salon visits, on holiday, at the gym, or anywhere else life happens to take you. Lightweight enough to forget you’re wearing it. Powerful enough that you’ll absolutely notice when you don’t.
Made for Real Life
The 45ml size isn’t just convenient — it’s smart. Airline liquid-limit friendly, small enough for any bag, and perfectly sized to try the formula for the first time without committing to a full bottle. Keep one at home. Keep one on the go. Keep your blonde looking like you just stepped out of the salon.
Five Aggressors. Zero Chance.
Every day your blonde faces a lineup of enemies determined to dull, damage and dehydrate it. Blonde Guard takes them all on:
- 🔥 Heat — blow-dries, straighteners, curlers
- ☀️ UV Damage — sun exposure that fades and brasses colour
- 🏊 Chlorine — the poolside colour-killer
- 🌊 Salt Water — beautiful beaches, brutal on blonde
- 💧 Dryness — the everyday thief of softness and shine
The Science Behind the Shine
Powered by a dual-action Micronised Nourishment + Cuticle Brightening formula, this milky fluid floods the hair fibre with lasting moisture while smoothing the cuticle to maximise light reflection. The result is blonde that doesn’t just feel healthier — it visibly looks it.

- Hair feels hydrated for up to 3 days††
