Let’s be real: nothing ruins a good hair day like frizz. Whether it’s humidity, damage, or just plain unruly strands, we’ve all been there. But after using the Kerastase Discipline Collection, I can finally say my hair has entered its main character era—smooth, soft, and totally under control.

If you’ve been debating whether these luxe products are worth the hype (and the splurge), keep reading. I’ve broken down everything I tried, what worked, and some frizz-fighting tips that’ll change your routine forever. 💁‍♀️

🔍 What is the Kerastase Discipline Collection?

The Kerastase Discipline line is designed for those of us dealing with frizzy, unmanageable, or hard-to-tame hair. Whether you have fine waves or thick curls, this collection aims to provide smoothing, control, and softness without sacrificing movement.

Each product contains Morphe-Kératine™ Complex, which helps restore the hair fiber, enhance elasticity, and control frizz with lasting results.

Here’s everything I tested:

Kerastase Bain Fluidealiste Shampoo bottle in a sleek pink and silver design, perfect for cleansing frizz-prone hair gently.

🧴 1. Bain Fluidealiste Shampoo

Let’s start with the base. This sulfate-free shampoo surprised me in the best way. It gives a light, creamy lather and leaves your hair feeling super clean—but not squeaky or dry.

Pros:

Great for daily use
Works on color-treated hair
Hair feels silky even before conditioner

Pro Tip: Massage in gently and rinse with lukewarm water to help the smoothing ingredients work better.

Lightweight Kerastase Fondant Fluidealiste Conditioner bottle, designed for smoothing and detangling frizzy or unruly hair.

💆‍♀️ 2. Fondant Fluidealiste Conditioner

Lightweight, but powerful. This conditioner is perfect if you have fine to medium hair that gets weighed down easily.

What I loved:

Detangles like a dream
Doesn’t leave a heavy film
Adds a soft, touchable finish

Pro Tip: Leave it in for 2-3 minutes while you shave or exfoliate—hello multitasking!

Kerastase Fluidissime Spray bottle, a lightweight heat protectant and anti-frizz spray offering up to 450°F heat protection.

💨 3. Fluidissime Anti-Frizz Spray

This heat protectant + anti-frizz spray is the unsung hero of the entire collection.

Why it’s a must-have:

Protects hair up to 450°F
Adds lightweight shine
Reduces drying time (yes, please!)

Tip: Spray it evenly before blow-drying for salon-sleek results. Bonus: it smells heavenly.

Rich and creamy Kerastase Maskeratine hair mask jar, formulated for deep conditioning and long-lasting frizz control.

🧖‍♀️ 4. Maskeratine Hair Mask

This deep conditioning treatment is a holy grail moment. Rich, creamy, and intensely nourishing—perfect for weekly use.

Best for:

Thick, coarse, or dry hair
Post-color treatment hydration
Long-lasting smoothness

Pro Trick: Apply with a wide-tooth comb for even distribution and leave on for 5–10 minutes under a shower cap for a DIY spa moment.

Kerastase Keratine Thermique Primer tube, a smoothing leave-in heat protectant cream ideal for prepping hair before styling.

🔥 5. Keratine Thermique Blow-Dry Primer

I call this the frizz insurance step. It’s a leave-in cream that preps your hair for heat styling and protects against humidity.

What makes it magic:

Smooths without greasiness
Helps your blowout last longer
Reduces breakage over time

Bonus Tip: Use a dime-sized amount from mid-length to ends—don’t overdo it!

💡 Final Thoughts: Is It Worth It?

Honestly? YES. If frizz and flyaways are your constant struggle, this line is a game-changer. While it’s an investment, a little goes a long way, and the results are so worth it. Especially when used as a system, these products bring that salon-finish feel right into your daily routine.

🧠 Extra Hair-Saving Tips:

Sleep on a silk pillowcase to reduce friction and keep hair smooth overnight.
Use a microfiber towel or cotton t-shirt to dry your hair—regular towels can rough up the cuticle.
Don’t skip the heat protectant… ever.
Trim your ends regularly to keep hair healthy and prevent split-end frizz.
