I Tested the Top Hair Heat Protectants and These Are the Results 🔥

Hey glow girl 🌸

Okay, let’s be real—

heat styling is one of those “love-hate” things. I love what my curling wand can do… but the dry ends, breakage, and heat damage? Not so much.

As someone who’s on a constant hair glow-up journey (aren’t we all?), I decided it was time to stop guessing and actually test the top-rated heat protectants to see which ones are worth the hype.

Because if I’m going to blow-dry, curl, and straighten my way to hair happiness, I need a ride-or-die protectant that’s actually doing something.

So I tried 6 popular heat protectants—on clean hair, styled the same way each time—and tracked how my hair felt, looked, and behaved.

Let’s get into the tea ☕️ (or the shine spray, in this case).


🧪 How I Tested Them:

  • I applied each product to freshly washed, towel-dried hair.

  • Blow-dried using medium heat, then styled with either a curling wand or flat iron.

  • Checked for:

    • Smoothness

    • Frizz control

    • Shine

    • Scent

    • Residue or stickiness

    • Next day feel

1. Olaplex No.9 Bond Protector Nourishing Hair Serum

💰 $$ | ⭐️ 8.5/10

My thoughts:
This one feels bougie—in the best way. Lightweight, non-greasy, and it gave me salon softness after just one use. My hair felt protected without being weighed down. The shine was subtle but chef’s kiss.

What I loved:

  • Zero residue

  • Sleek finish

  • UV protection bonus!

What I didn’t:

  • A bit pricey for everyday use.

  • Doesn’t help a ton with frizz unless you pair it with a smoothing cream.

Final vibe:
Quiet luxury in a bottle.

2. CHI 44 Iron Guard Thermal Protection Spray

💰 $ | ⭐️ 6/10

My thoughts:
This one has been around forever, so I had high hopes—but it didn’t quite wow me. The scent is strong (like, hairspray strong), and while it did protect from heat damage, it left my hair feeling a little crunchy.

What I loved:

  • Budget-friendly

  • Definitely minimized split ends over time

What I didn’t:

  • Sticky if you use too much

  • Not ideal for fine or soft hair types

Final vibe:
🧯 Gets the job done, but not my fave for daily use.

3. TRESemmé Thermal Creations Heat Tamer Spray

💰 $ | ⭐️ 7.5/10

My thoughts:
If you're a drugstore girlie like me, this one is a solid pick. It smells amazing, sprays evenly, and leaves your hair soft. Not super glossy or transformative, but very dependable.

What I loved:

  • Lightweight

  • Great for everyday blow-drying

  • Budget win!

What I didn’t:

  • Doesn’t fight frizz well

  • Slightly sticky if you go overboard

Final vibe:
💁‍♀️ Cute, casual, and dependable—like your hair’s bestie.

4. Kenra Platinum Blow-Dry Spray

💰 $$$ | ⭐️ 9.5/10

My thoughts:
Okay, wow. This one turned my hair into actual silk. Blow-drying was faster, smoother, and I noticed way less frizz. Plus, it smells like a sweet, grown-up perfume.

What I loved:

  • Cuts drying time by half (yes, really)

  • Amazing smell

  • Mega shine

What I didn’t:

  • On the pricier side

  • Works best for medium to thick hair (might be heavy for super fine strands)

Final vibe:
🌬️ Blow-dry bar results at home.

5. Gisou Honey Infused Heat Protecting Serum

💰 $$$ | ⭐️ 8/10

My thoughts:
The aesthetic? Immaculate. And the smell? Like a literal dream. This heat protectant is light and nourishing, and the honey infusion definitely made my hair feel softer and more hydrated.

What I loved:

  • Beautiful scent

  • Clean ingredients

  • Non-greasy formula

What I didn’t:

  • Pricey

  • Not a major frizz-fighter if humidity is your enemy

Final vibe:
🍯 Sweet, soft, and so pretty on your shelf.

6. Living Proof Perfect Hair Day Heat Styling Spray

💰 $$ | ⭐️ 9/10

My thoughts:
This one gave me model-off-duty hair. Lightweight, invisible, and made my style last way longer than usual. My curls stayed bouncy and shiny without getting crunchy.

What I loved:

  • No scent (if you’re sensitive to smells!)

  • Perfect for re-styling

  • Keeps hair soft even after straightening

What I didn’t:

  • Slightly drying if you don’t follow with a leave-in conditioner

Final vibe:
📸 Photo-shoot ready without the fuss.

💖 My Final Ranking (From Personal Fave to "Meh")

  1. Kenra Platinum Blow-Dry Spray – smooth, shiny, worth the splurge

  2. Living Proof Heat Styling Spray – lightweight, long-lasting, everyday chic

  3. Olaplex No.9 Serum – nourishing and luxe

  4. Gisou Honey Protectant – soft & sweet but not for frizz

  5. TRESemmé Heat Tamer – budget basic but reliable

  6. CHI Iron Guard – too sticky for my liking, but protective


💡 Final Thoughts: What I Learned on My Heat-Protectant Journey

Girl math: If I’m investing time into curling my hair, I deserve protection that works AND makes my hair look cute.


I learned that not all sprays are created equal, and the best one depends on your hair type and styling habits.

If you're heat styling more than 3x a week, I’d 100% recommend investing in something a little higher-end (like Kenra or Living Proof). But if you’re just blow-drying and doing the occasional curl? A trusty drugstore protectant will still keep your strands safe.

With love and soft strands,
