1. What is Blond Guard?
   Kérastase Blond Guard is your blonde's best defence. Think of it as a hydrating shield, it deeply nourishes lightened, highlighted, and colour-treated hair while blocking 99% of blond aggressors: heat, UV damage, chlorine, salt water, and dehydration. It's the product we recommend to every blonde client who wants to protect their investment.
2. Does Blond Guard apply to wet or dry hair?
   Apply it to towel-dried hair after washing. That's when your hair is most receptive, it locks in intense hydration, feels completely weightless, and gets to work protecting your colour from the moment you step out the door.
3. Can Blond Guard be used as a finishing product on dry hair?
   This one's for wet hair only! Blond Guard is a leave-in treatment, not a finishing product; it needs to be applied before styling to do its job properly.
4. Does Blond Guard need to be rinsed out?
   Not at all, that's what makes it so easy to love. It's a leave-in lightweight shield, so you apply it and go. No extra steps, no rinsing.
5.  Is Blond Guard a heat protector?
   Yes, and a serious one. Blond Guard protects your hair from heat styling up to 230°C (446°F), making it a non-negotiable step before you pick up any hot tool.
6.  What are the 99% of blond aggressors?
   Blond Guard is formulated to block five of the biggest threats to blonde hair: heat, UV damage, chlorine, salt water, and dehydration. Basically, it's got you covered whether you're at the beach, the pool, or just your morning blowout.
7. What does each aggressor actually do to my hair?
   Great question, here's the breakdown:

• Heat from styling tools weakens the cuticle and cortex from the inside out, causing protein loss, breakage, and visible surface damage over time. A heat protector isn't optional; it's essential.
• UV exposure breaks down your hair's proteins and lipids, leading to colour fade, loss of shine, and increased porosity. Blonde hair is especially vulnerable here.
• Chlorine acts as an oxidizing agent that can turn blonde hair brassy, strip its shine, and make it harder to detangle, effects that get worse with sun exposure layered on top.
• Salt water drives minerals deep into the hair fibre, increases porosity, and pulls out moisture, leaving hair rough, dull, and depleted, particularly if it's already sensitized from colour services.
• Dehydration is what happens when all of the above pile up. Dryness, roughness, and lost luminosity are the result, which is exactly why daily hydration and protection aren't a luxury; they're maintenance.
