Blow Wave = Flop Wave? Here’s Why.
You spent time sectioning, blow-drying, brushing, even saying a little prayer to the hair gods — and still, by lunchtime, your blow wave looks like it never happened.
We feel your frustration.
But it’s not just humidity or bad luck. It usually comes down to a few key things most people don’t realise they’re doing wrong at home.
Let’s break down the 5 biggest reasons your blow wave flops — and how to fix them so your style holds strong, shiny, and fabulous all day long.
1️⃣ You Didn’t Use Any Prep Products
We get it — you just washed your hair, it smells great, and you’re ready to dry and dash.
But skipping prep products is like trying to build a house with no foundation.
Blow wave success starts before the dryer switches on. You need styling support that gives grip, body, and memory.
💡 Pro Tip:
For fine to medium hair, try Kérastase Genesis Défense Thermique It nourishes without weighing down, and helps your style hold its shape with a satin finish.
2️⃣ You Didn’t Use Heat Protection
Your flat iron gets hot enough to cook bacon. Same with your dryer. And still — no heat protection?
Heat damage doesn't just cause breakage — it destroys hold. When your hair cuticle is compromised, it can't hold shape, volume, or curl.
💡 Pro Tip:
Always apply a thermal protector. If you’re already using Kérastase Genesis Défense Thermique, you’re covered — it protects up to 230°C. Bonus: your hair will feel smoother too.
3️⃣ Your Hair is Damaged
Split ends, breakage, and brittle strands don’t behave — no matter how many round brushes you own. Damaged hair has uneven texture and poor elasticity, which means it won't hold any shape for long.
💡 How to Fix It:
Invest in regular trims and deep treatments. We love Kérastase Masquintense and our in-salon CH-ONE or K18 treatments to bring your strands back to life.
4️⃣ You're Using the Wrong Technique for Your Hair Type
Let’s say it louder for the people in the back: Fine hair is not thick hair.
They need different approaches.
Fine hair? You need volume at the roots and lightweight products that build body. Don’t overload with oils and creams.
Thick hair? You need smoothing, control, and tension when blow-drying. Skipping product will leave you with puff, not polish.
💡 Pro Product Pairings:
Fine Hair: Nutritive Thermique
Thick Hair: Discipline Keratin Thermique
Tailor your technique and tools to your hair texture, and you’ll see a major difference in hold.
5️⃣ You Didn’t Let It Set
Imagine curling a ribbon with scissors, then pulling it flat immediately after.
That’s exactly what happens when you don’t let your hair cool in shape before touching or brushing it.
Hair is most pliable when hot — but unless it’s cooled, it won’t keep that shape. Think of it as “locking in” the blow wave.
💡 The Fix:
Let each section cool fully, ideally while still wrapped around your brush or clipped in place. Yes, it takes a minute — but your blow wave will thank you.
💬 Final Thoughts:
A blow wave that falls flat is not your destiny.
With the right prep, protection, and pro-approved techniques, your style can last through work meetings, dinner plans, and everything in between.
