Why Oil-Free
Shampoo?

Dandruff is caused by a fungus called malassezia which feeds on oils. Most shampoos contain oil and promote the growth of malassezia.

Dermazen formulas give unique relief because we never use oil-based ingredients that can increase the growth of fungus.

Why It Works: Our 3-Step Process

1. Disrupt the Biofilm

Malassezia fungus creates a biofilm shield that protects itself from antifungal treatment. We’ve unlocked the secret to help safely diminish or neutralize this barrier.

2. Clear the Fungus

Once the biofilm is removed, our products work together to help reduce signs of fungus easier than ever. We use skin-safe antifungal-based ingredients powered by Mother Nature.

3. Soothe the Skin

Now it’s time to nourish and hydrate your skin without using lipid-based ingredients (like coconut oil, jojoba, etc.) that can help increase the growth of Malassezia fungus.

Keeping it Zen

We practice ingredient minimalism. Our goal is to keep the list of ingredients humble while formulating products more effective than anything else. That’s why you won’t find parabens, sulfates, fragrances, or hard-to-pronounce chemicals. Those are the opposite of peaceful.

    Never knew what a healthy scalp was like

    My entire life I've suffered from a flakey dry scalp. Growing up I was embarrassed and thought I would be made fun of for dandruff. I tried many different products ranging from overnight lotions to the classic head and shoulders routine but none of really solved the issue of flakes.

    After using the shampoo from dermazen two times my flakes were straight up gone. Not only that but my scalp felt healthier, I had less hair falling out in the shower and way less oil being produced between rinses.

    All this just from the shampoo!! I'm not a fan boy for products but I have zero plans to shop anywhere else for scalp care. It's a no brainer for me.

    Great for textured hair and skin

    Absolutely love this shampoo. I have locs and this shampoo does a really good job of soothing my scalp without sacrificing moisture. My scalp will also cause flare ups around the perimeter of my face. Leaving Cystic nodules and painful acne. I resulted to also adding this to my skin care regime as well. Works just as well on the face as the scalp. I have tried the face wash but the shampoo works better for some reason. Love all their products!!!

    Daivonya, it's incredible hearing that the Scalp Therapy Shampoo is working so perfectly for both your locs and your skin! Also, it's soothing your scalp while keeping your hair moisturized—finding that perfect balance can be so challenging with textured hair? Our ears are clapping tbh. What really amazes us is how you discovered it works even better on your face than our actual face wash for those stubborn cystic nodules and painful breakouts around your hairline! Sometimes our customers find the most brilliant ways to use our products that we never even expected. The fact that you've incorporated it into your skincare routine and it's delivering such amazing results for those scalp-related flare-ups shows just how versatile and effective it really is. Knowing that you love ALL our products means EVERYTHING to us! 💚✨

    Good product

    I use this along with the Mct Scalp moisturizer and serum. I believe this is helpful with my scalp. I don't care for the smell of the shampoo though.
