Moroccan Oil for Summer Frizz: Does It Really Thicken Hair?

Table of Contents

What I Found After Testing It in July Heat (Plus How It Compares to Verb)

Folks, here’s the deal when summer hits hard and the humidity rises faster than a kettle on a campfire, frizz becomes public enemy number one. I’ve spent decades in the trenches of hair testing, and let me tell you, not every product can stand up to 90% humidity and dew points pushing 70. But I’ve got something worth talking about: Moroccanoil Treatment Purple Hair Oil.

Now, I didn’t just stop there. I put it head-to-head with one of my personal favorites, Verb Hydrate Oil. Let’s see how they stack up.

What’s the Deal with Moroccanoil Purple?

This one’s made for color-treated hair blondes especially but the real kicker is how well it tackles frizz without greasing you up like a diner skillet. It’s light, smells fantastic, and makes your strands feel thicker and softer.

Price per ounce: ~$22.23 (1.7 oz total)
Best for: Short to medium hair, color-treated strands
How it performs: Adds fullness, removes frizz, enhances shine

I tested it in brutal July heat, and folks, this oil held its ground.

Moroccan Oil vs. Verb Hydrate Oil: Which Wins?

Honestly? If you blindfolded me, I’d struggle to tell ‘em apart in performance. But Moroccanoil wins in the ease-of-use department.

The Test: Real Summer, Real Hair

Side-by-side comparison photo of the back of a woman’s head showing mid-length, color-treated hair. The left side (before) shows frizzy, wavy hair labeled “Day 1: 90° + Dew Point 70,” while the right side (after) shows smooth, straightened hair labeled “After Moroccan Oil Purple.” Both images have a neutral beige background and the woman wears a black T-shirt.

It was 94°F, dew point 74, and I was running errands like any normal day. I worked a dime-sized amount into my dry hair just mids to ends and got:

No frizz
Noticeable thickness
Zero greasy feel
All-day softness

And it smelled good, folks. Clean and slightly sweet, but not overwhelming. Like summer in a bottle.

Price Talk: Are They Worth It?

Sure, they ain’t cheap. But both oils last months if used right. For me, with medium-length hair, one bottle covers an entire summer.

“You didn’t come this far to only come this far invest in your hair and your sanity.”

How Does It Compare to the Viral Moroccanoil Frizz Shield Spray?

There’s a lot of buzz around the Frizz Shield Spray and for good reason. It’s lightweight, smells clean (though some folks don’t love it), and works well when blow-dried in. It’s about $5.93 per ounce, which makes it more affordable than the oils.

But here’s the thing:

It’s watery by design it needs to mist, so the formula is thinner.
Great for light frizz control on fine or medium hair.
But for thick, coarse, or very humid days?

“Go oil. Every time. It coats better, lasts longer, and holds up when the humidity gets biblical.”

Spray = daily smoothness / Oil = hardcore humidity control

Go Moroccan Oil if:

You don’t want a pump
You like luxe, clean scent

Go Verb if:

You want a similar effect for a bit less per ounce
You don’t mind fighting the pump now and then

Go Frizz Shield Spray if:

You style with heat daily and want a light, mistable option
Your hair is fine-to-medium and you prefer sprays over oils

“Personally? I use both the oil and the spray depends on the day and the dew point.”

Bonus: How to Apply Hair Oil Like a Pro

A close-up photograph of a left human hand with a small, pea-sized drop of hair oil resting in the center of the palm. The skin is warm-toned and well-lit, set against a neutral beige background. Overlay text at the bottom reads, “Start small, pea size” in a clean, black font.

One of the biggest mistakes I see? Folks dumping too much on like it’s aftershave. Here’s how to use it right:

Start with dry or towel-dried hair.
Pump a pea-sized amount into your palm.
Rub hands together to warm and distribute.
Gently rake through mids to ends avoid the roots.
Need more? Add a little at a time. Don’t go full splash mode.

Your hair will thank you later.

Meesh’s Take (30s, Style Enthusiast)

“Girl, this stuff handled frizz faster than your ex ghosted you. I love Verb, but I can’t deal with a broken pump at 7am. Moroccanoil gave me shine, softness, and bounce without feeling like I had oil slicks on my roots.”

She’s got thick, wavy hair and uses it sparingly post-blowout.

Stacey Bee’s Perspective (50s, Aging Hair Expert)

“After 50, hair needs moisture, but not weight. This oil adds silkiness without heaviness especially important for thinning or brittle hair. I recommend Moroccanoil Purple to clients with color-treated strands needing frizz control and shine.”

She’s tested hundreds of oils. This one made the cut.
