I Tried the ROZINO Keratin Shampoo for My Greasy Scalp—Here’s the Tea

By Sarah M. | Updated October 24, 2023

Listen, I’m going to be completely real with you. If you’ve ever looked in the mirror at 3:00 PM and wondered if someone poured a literal bottle of olive oil over your head while you weren’t looking, we are in the same boat. My scalp has always been… well, “challenging” is a nice way to put it. Oily by noon, itchy by dinner, and those tiny white flakes? Yeah, they’ve been my unwanted accessories for years.

I’ve spent a ridiculous amount of money on high-end salon brands that promised the world and delivered absolutely nothing but a lighter wallet. So, when I saw the ROZINO Keratin Shampoo popping up in my feed, I was skeptical. Another “deep cleansing” shampoo? I thought. Probably just another bottle of harsh sulfates that’ll leave my ends feeling like hay.

But here’s the thing: I’ve been using it for two weeks now, and my hair actually feels… fluffy? Like, legit volume that doesn’t collapse the moment I step outside. I figured it was time to sit down and write this ROZINO review honest and raw, because if you’re struggling with the same “greasy-root-dry-end” struggle, you need to know if this stuff actually works.

First Impressions: The Vibe and the Smell

Can we talk about the scent for a second? Opening the bottle of the ROZINO Keratin Shampoo isn’t like opening a typical drugstore shampoo. It doesn’t have that fake, overwhelming “ocean breeze” smell. It’s got this cooling, minty undertone that immediately makes you feel like you’re in a spa. It’s fresh, it’s clean, and it actually helps neutralize that “sweaty hair” smell after a workout—you know exactly what I’m talking about.

The texture is what really surprised me. It’s silky, almost like a gel-cream hybrid. It’s not sticky at all. When you rub it between your hands, it creates this super dense, rich lather. I’m a sucker for a good foam, and this one feels expensive. It’s easy to push through your hair, which is great because I hate it when shampoos feel like they’re tangling your hair as you wash it.

What’s Actually Inside This Bottle?

I’m not a chemist, but I’ve become a bit of an ingredient nerd lately. I looked at the back of the bottle and was actually pretty impressed. It’s not just a bunch of detergents. Here’s what caught my eye:

• Keratin: This is the big one. It’s supposed to repair the hair structure. My hair usually feels pretty brittle, but the keratin seems to give it a bit more “snap.”
• Biotin: I take biotin supplements, but having it in my shampoo? Yes, please. It’s known for supporting hair health and making things look a bit fuller.
• Mint: This is where that cooling sensation comes from. It’s amazing for scalp oil control because it feels like it’s actually waking up your skin.
• Coconut Oil & Black Sesame: These are the “moisture” players. They keep the deep cleansing shampoo from being too aggressive.

The “Does It Work?” Test

I followed the directions—which, by the way, suggest a 3-5 minute massage. Honestly, who has 5 minutes? But I tried it. I put on a podcast, massaged my scalp, and let the minty goodness sit there. When I rinsed it out, my hair didn’t have that “squeaky” feeling. You know the one? Where it feels so clean it’s almost vibrating and impossible to comb? This wasn’t like that. It felt smooth, but my scalp felt… light. Like it could finally breathe.

After blow-drying, the difference was obvious. Usually, by the time I’m done drying my hair, the roots already look a bit flat. With this anti-dandruff shampoo, my hair had this “swish” to it. It was soft, moist (in a good way!), and the dandruff I usually see at my hairline was nowhere to be found.

How It Compares to the Competition

I’ve tried everything from the $5 bottles at the grocery store to the $60 luxury brands. Here is how I think the ROZINO Keratin Shampoo stacks up:

The Good, The Bad, and The Honest

No product is perfect, and I wouldn’t be doing my job if I didn’t tell you the downsides. Is ROZINO shampoo worth it? Mostly yes, but here’s the breakdown:
