Is Mythic Oil Shampoo Good For Hair? (The Truth No One Tells You)

Ever stared at your reflection thinking, “Why does my hair look like a dry broomstick today?” Yep. Been there. And that’s usually the moment we start scanning shelves for something anything that promises smooth, shiny, salon-like hair. Enter: Mythic Oil Shampoo by L’Oréal Professionnel.

It’s got the name, the gold bottle, the argan oil whispers, and that luxurious scent that makes you want to sniff your hair like a weirdo in public. But… is it actually good for your hair?

Let’s talk. No jargon. No hype. Just the real, expert-led lowdown on what it does, who it works for, and whether it’s worth your coin.

First Things First: What Is Mythic Oil Shampoo?

So Mythic Oil Shampoo is a part of the Mythic Oil line from L’Oréal Professionnel, which includes oil, masque, and conditioner. It’s loaded with argan oil and myrrh extract fancy, right?

It promises to:

• Nourish hair deeply without weighing it down

• Leave hair smooth, shiny, and frizz-free

• Work especially well for dry, thick, or rebellious hair

Sounds dreamy. But let’s get nerdy with the facts.

Ingredient Breakdown (Because I Always Check the Label)

Let’s peek at what’s actually inside.

✅ Argan Oil

Rich in Vitamin E and fatty acids. This is what gives the shampoo its nourishing punch. It smooths out frizz, seals split ends, and adds shine.

✅ Myrrh Extract

Used historically for healing wounds. In hair care, it’s praised for its antioxidant and protective properties. Bonus: smells divine.

❌ Sulfates (Sodium Laureth Sulfate)

Yes, Mythic Oil Shampoo is NOT sulfate-free. That might be a turn-off if you’re into the “clean beauty” game. But for thick, heavy hair types or those used to richer shampoos, sulfates help with that satisfying lather and deep cleanse.

Quick Fact Box

Is Mythic Oil Shampoo Sulfate-Free?
Nope. It contains Sodium Laureth Sulfate great for lather, not ideal for color-treated or sensitive scalps.

Okay, So… Is It Good for My Hair Type?

Short answer: Depends on your hair’s mood (and history).

Good For You If…

• Your hair is thick, coarse, or unruly

• You struggle with frizz or dullness

• You like luxurious, spa-like scents

• You blow-dry or straighten often and need a moisture boost

Skip It If…

• Your hair is fine, limp, or super oily it may feel heavy

• You have color-treated hair and want sulfate-free options

• Your scalp is sensitive or eczema-prone

What Research Says (Not Just Hype)

According to a consumer study by L’Oréal Professionnel, 89% of women who used the Mythic Oil range said their hair felt smoother and easier to manage after one week of use.

But here’s the real kicker: Argan oil has been proven in multiple dermatology studies to increase hair elasticity, reduce breakage, and improve hydration over time. It’s not a “miracle,” but it’s definitely science-backed.

Real Life Test: I Used It for 4 Weeks Here’s What Happened

Week 1

First wash? Hair felt soft. But slightly coated. I wasn’t sure if that was oil or buildup.

Week 2

Less frizz. Smoother ponytail days. My hair smelled gorgeous that deep musky-floral thing? Addictive.

Week 3

The volume dropped slightly. But shine? Boosted. It was giving me those “I just got a blowout” vibes without actually doing one.

Week 4

Ends looked healthier. Fewer flyaways. Definitely looked more polished, even on air-dry days. But I did feel the need to clarify once with a different shampoo just to remove some buildup.

How to Use Mythic Oil Shampoo (The Right Way)

Here’s how to get the most out of it:

1. Start with warm water – Opens up the cuticle and helps the oil penetrate.

2. Use a small amount – A little goes a long way.

3. Massage your scalp – Gently, for 1–2 minutes to stimulate blood flow.

4. Rinse with cool water – Helps seal the cuticle and lock in shine.

5. Pair with Mythic Oil Conditioner or Mask – For full effect. Especially if your hair’s dry or damaged.

When Should You Use It?

• Once or twice a week if you have dry hair.

• Alternate with a clarifying or sulfate-free shampoo if you use it daily.

• Always follow up with a conditioner or oil this shampoo works best as part of a full routine.

But Wait Is It Better Than Other Oil Shampoos?

That’s a tricky one. Mythic Oil is rich, hydrating, and smells luxurious. But compared to sulfate-free oil shampoos like OGX Argan Oil or Maui Moisture, it may not be as scalp-friendly.

Versus OGX Argan Oil Shampoo

• OGX is sulfate-free and lighter

• Mythic Oil is creamier, more nourishing

• OGX better for fine hair; Mythic better for thick hair

Versus Moroccan Oil Moisture Repair

• Moroccan Oil is also luxurious, but pricier

• Both contain argan oil

• Moroccan Oil wins for long-term repair; Mythic wins for instant shine

Final Verdict: Is It Worth It?

Yes, if you want hair that looks instantly smoother, feels more manageable, and smells like you own a yacht.

No, if your hair’s fine, you’re strictly sulfate-free, or you’re prone to scalp issues.

Summary

What I Recommend (As a Hair Analyst)

If you have coarse, rebellious hair that craves moisture go for it. But use it alongside a clarifying shampoo every few washes to avoid buildup.

And if you’re on the fence? Grab the travel size first. See how your hair feels after 2–3 washes. Sometimes, it’s love at first lather. Sometimes… it’s a “meh.”

But don’t just trust the bottle. Trust how your hair feels.

Ingredient Note Box

Sensitive to Sulfates?
Look for these alternatives:

• SheaMoisture Raw Shea Butter Moisture Retention Shampoo

• Maui Moisture Heal & Hydrate Shampoo
  Both are gentler on the scalp and color-safe.

My Closing Thought

Hair care isn’t one-size-fits-all. Mythic Oil Shampoo can be amazing but only if it suits your hair’s story. Listen to your strands. They’ll tell you what they need.
