Pine Tree Terpenes (Citropol )

Citropol
Silicone-Free. Frizz-Free. No Compromise.

For decades, silicone has been the default ingredient for smooth, manageable hair. It works by coating the strand with a synthetic film that temporarily tames frizz and adds slip. The problem? Silicones are not biodegradable; they build up on your hair over time, and they sit on a clean beauty no-fly list for good reason. Citropol is the answer the industry has been working toward.

What It Is
Citropol is a plant-derived, forest-sourced polymer made from terpenes, the naturally occurring compounds found in pine trees. It is biorenewable, 100% biodegradable, and certified to meet Forest Stewardship Council (FSC) standards. Every molecule is upcycled from a byproduct of the paper-making process, meaning nothing goes to waste. It is one of the very few ingredients that is genuinely better than silicone in both performance and sustainability.

How It Works
Citropol coats each strand with a lightweight, uniform layer that smooths the cuticle, reduces friction, and locks out humidity. Unlike silicone, which sits on top of the hair and accumulates with repeated use, Citropol integrates cleanly and leaves no heavy residue behind.


The result is hair that moves, feels natural, and stays smooth without the weight or buildup you'd expect from a conventional anti-frizz ingredient.

What the Science Shows
When tested head-to-head against a benchmark silicone, Citropol outperformed across every key hair care metric:

- 58% reduction in frizz vs. 55% for silicone, in controlled testing
- 45% less product buildup after 10 applications compared to silicone
- Heat protection up to 450°F, guarding hair from styling damage
- Humidity resistant, keeping frizz at bay even in high-moisture conditions
- Improved combability and shine, without grease or residue

Clean Credentials
Citropol carries one of the cleanest sustainability profiles of any performance hair ingredient available. It is biorenewable, biodegradable according to the OECD 301B standard, non-toxic, and non-allergenic. The terpenes it is made from are FSC-certified pine, upcycled from what would otherwise be an industrial byproduct.


No silicones. No synthetic buildup. No environmental trade-off.
Just smooth, healthy hair, straight from the forest.

Castor Oil Esters (Proshine)

The Science of Seriously Shiny Hair
Shine isn't just cosmetic. It's actually a sign of health. When a hair cuticle lies flat and smooth, light reflects evenly off it, creating that glossy, vibrant look. When it's lifted or damaged by heat, chemicals, or UV exposure, light scatters instead of reflecting, and the result is dull, flat hair.

What It Is
A 100% plant-based ester derived from castor oil, developed under Green Chemistry principles. Zero synthetic silicones. 100% biodegradable.

How It Works
ProShine® binds directly to keratin proteins inside the hair fiber, forming a uniform molecular coating with a high refractive index. Engineered to reflect light with intensity and consistency across every strand.

What the Science Shows
ProShine® was clinically tested across virgin, bleached, and color-treated hair, and the results speak clearly:

- 184% more shine on natural hair vs. placebo
- 428% more shine on bleached hair vs. placebo
- 127% shinier bleached hair vs. untreated strands
- 42% shinier color-treated hair vs. untreated strands
- Enhances the vibrancy of dyed hair, helping color look fresher for longer

These results hold across all hair types and textures, whether your hair is natural, lifted, or chemically treated.

Clean Credentials
ProShine® is derived entirely from castor, a renewable plant source, and produced under Green Chemistry guidelines. It's 100% biodegradable, contains zero synthetic silicones, and delivers real optical performance without any of the buildup or residue that traditional shine ingredients leave behind.


Brilliant hair. Clean formula. No compromise.

Ceramide NG (Hairflux™)

  • Scalp and strands, restored together.
    Healthy hair starts at the scalp. When it is irritated, dry, or inflamed, hair cannot thrive no matter what you put on the lengths. At the same time, color, bleach, and chemical treatments break down the fiber from within, weakening the structure that keeps strands strong. Most ingredients address one or the other. Hairflux® addresses both at once, leaving the scalp visibly calmer and the fiber measurably stronger after just two weeks.

    What It Is
    Hairflux® is a bio-inspired ceramide complex combining plant-derived Ceramide NG with Olive Fruit Oil and Castor Seed Oil. Developed through over 20 years of ceramide science, it is the only ingredient in this formula engineered to work simultaneously on the scalp environment and the hair fiber itself.

    How It Works

    For the Scalp
    Scalp discomfort is more common than most people realize, affecting around 60% of women and 40% of men. Hairflux® works by reducing Interleukin-1, one of the primary inflammatory proteins behind dryness, redness, and itching. The result is a calmer, more balanced scalp environment where hair is able to grow and behave the way it should.

    For the Fiber
    Chemical treatments break down the internal protein structure of each strand, causing the fiber to swell, weaken, and become prone to breakage. The ceramide complex in Hairflux® penetrates the fiber and repairs that damage from within, restoring structural integrity and reducing the swelling that makes chemically treated hair feel rough and behave unpredictably.

    What the Science Shows
    Clinically tested on panelists with dry, itching scalps and visible redness, and on chemically treated hair across all hair types. Results confirmed by clinical expert grading and before-and-after photography.
  • Measurable improvement in scalp dryness, redness, and itching after two weeks, confirmed by clinical grading
  • 82% repair effect on chemically straightened hair via clinical fiber stress testing
  • 75% reduction in swelling of bleached hair, restoring the fiber closer to its virgin state
  • Reduces breakage on color-treated, bleached, and chemically processed hair
  • Validated across all hair types, including Afro-textured, Asian, and European hair

Clean Credentials
Hairflux® is built on over 20 years of ceramide science and delivered through a bio-inspired, plant-derived complex. Ceramide NG mirrors the ceramides naturally found in the scalp and hair fiber, which means the body recognizes it and works with it rather than against it. Paired with Olive Fruit Oil and Castor Seed Oil, it is a formula that earns its results through biology, not chemistry shortcuts.

Bataua Superfruit Oil (Oenocarpus Bataua Fruit Oil)

Regeneratively harvested, Bataua Oil moisturizes and protects the scalp's lipid layer, which is essential for healthy skin. An antioxidant powerhouse, it boasts high levels of Oleic, Palmitic, and Stearic Acids—the ultimate trio for profound, enduring moisture. 

To highlight its potency, consider this: Bataua oil contains 63 times more Vitamin E per milligram than Avocado oil.

Recognized as nature's most potent moisturizing agent, Oleic acid is abundantly present in Bataua, surpassing concentrations found in any other natural source on Earth. Once our skin absorbs Oleic acid, with Bataua showcasing unparalleled absorption, the harmonious action of Stearic and Palmitic acids comes into play, sealing in the moisture with unmatched effectiveness.

Hemisqualane (C13-1 Alkane)

Who needs silicones when you can harness the nourishing powers of Hemisqualane. Derived from responsibly sourced sugarcane, this meticulously crafted elixir is bio-fermented to unleash its unparalleled potential in transforming your locks. Hemisqualane represents the pinnacle of hair health, deeply penetrating and revitalizing every strand.

  1. Works well

    I have 2A/2B fine, medium porosity, wavy hair that's extremely frizz-prone and humidity sensitive. I've tried countless products for heat protection and frizz control but everything weighed my hair down — until I found the Standard Oil. It's lightly scented and never weighs my hair down. Does it completely tame my frizz? No - but my hair is stubborn, so good enough is actually a win! I previously used this alongside the SuperFinish Polishing Balm which was an absolute game changer for frizz control but sadly that's been discontinued. The Standard Oil alone still performs well and has earned a permanent spot in my routine. Evolvh, PLEASE don't discontinue this product - I already ordered two bottles just in case! :laughing:

  3. Great shine!

    I love how shiny this makes my hair! It's also very light for an oil which is great for my fine hair.

  4. Give oils a chance!

    I have fine, curly hair and had written off oils of any kind. The Standard has changed my mind and my hair! From scrunching out my cast on wash day to adding moisture and shine between washes, this product does it all without weighing my curls down. The ingredients are clean, and I appreciate the lack of scent. Evolv products are straightforward and powerful products for my curls.

  5. I plan to purchase more!

    It leaves my hair soft, moisturized, and shiny, and helps cut down on frizz. I like the feel of The Standard hair oil much better than that of the Wonderbalm, because it is light-weight, and does not feel thick or viscous. The vanilla fragrance is not a stereotypical smooth, calming 'creamy' vanilla (which I expected), but more of a deep, fruity, woody, concentrated sort of Vanilla (the natural fragrance, itself, is not strong, though). It could definitely pass as a unisex scent and dissipates quickly enough to go unnoticed by others.
