Moisturizes dry hair, conditions nicely
I use this a couple of times a week to moisturize my dry hair. I just like how it conditions my hair.




































Structural repair, from the inside out
Most strengthening ingredients work at the surface. FiberHance™ BM goes deeper. It is a patented, glucose-derived molecule engineered to penetrate the hair's cortex and rebuild the hydrogen bonds that give hair its strength, elasticity, and natural density. Hair that went in feeling thin and fragile comes out feeling genuinely thicker and more resilient, with results that build with every wash.
What It Is
FiberHance™ BM is a first-of-its-kind patented small molecule evolved from glucose-based chemistry. Its molecular structure and dimensions were specifically engineered to penetrate deep into the hair's cortex, reaching the internal protein architecture where real strengthening happens.
How it Works
In damaged hair, the bonds inside the alpha-helix protein structure are broken or missing. FiberHance™ BM rebuilds them in two simultaneous ways: forming new hydrogen and ionic bonds within each alpha-helix, and bridging across adjacent helixes to reinforce the entire internal architecture. The result is a measurably stronger fiber from the inside out, not a surface deposit that washes away. Cortex penetration has been confirmed by FTIR imaging, distinguishing it from proteins, keratin derivatives, and oils that coat the cuticle without ever reaching the structure beneath.
What the Science Shows
Tested via cyclic tensile fatigue testing on single hair fibers. The higher the number of cycles to break, the stronger the hair.
Clean Credentials
FiberHance™ is derived from glucose, a natural sugar-based origin. It's produced through a zero-waste green manufacturing process, making it a responsible choice for both your hair and the planet. No silicones. No surface masking. Just real, science-backed repair.
Broken Bonds, Rebuilt From Within.
When hair is bleached, colored, or chemically treated, the disulfide bonds that hold its protein structure together break apart. Those broken bonds are what make hair feel weak, absorb too much moisture, lose its curl pattern, and look perpetually dull no matter what you put on it. TeraBond™ goes inside the fiber and rebuilds those connections at the molecular level. The result is hair that holds its shape, dries faster, reflects light cleanly, and feels visibly fuller from the inside out.
What It Is
TeraBond™ is a patented, 100% natural reactive repair system derived from two naturally occurring biological sources: Aspergillus ferment and Arginine. It is the only bond multiplier of its kind that covalently bonds directly to broken disulfide bonds in hair, regenerating the sulfur-to-sulfur connections that give hair its strength, shape, and resilience.
It is 100% natural, renewable, and holds a U.S. patent for its unique mechanism of action.
How It Works
When TeraBond™ is applied, its molecules seek out broken disulfide bonds within the hair's cortex and form new covalent connections at those exact sites. It is a chemical reaction that physically restores the bond structure of the hair from within, not a surface coating that mimics the appearance of repair.
As those broken bonds are rebuilt, four things happen simultaneously. The hair fiber regains its structural strength. The gaps and voids created by damage are filled, reducing the porosity that causes frizz, swelling, and uneven color absorption. The cuticle is smoothed, creating the kind of shine that looks like the hair is lit from within. And the hair becomes more hydrophobic, repelling excess moisture so it dries faster and holds its shape longer.
What the Science Shows
Tested at the Textile Research Institute in Princeton using Confocal Raman Spectroscopy, measuring disulfide bond content from the hair's surface down to 25 microns deep.
Clean Credentials
TeraBond™ represents a genuine innovation in bond repair. Its INCI is just two ingredients: Aspergillus Ferment and Arginine. Both naturally derived. Both clean by every standard that matters. It is renewable, patented, and free from the ethoxylated chemicals that compromise other bond repair technologies.
Four actives. Three simultaneous repair steps.
Built to address the kind of damage most treatments can't.
Not all damage is the same. Bleaching causes the most severe tensile strength loss of any chemical process, measured at nearly twice the impact of dyeing. But the way damage accumulates is layered: broken bonds, a compromised cuticle, increased porosity, and loss of the hair's natural hydrophobicity, all happening at once and all requiring a different repair mechanism to address. Most treatments address one layer. Restart PRO 1695 addresses all of them simultaneously.
What It Is
Restart PRO 1695 is a biotechnology-derived active complex made from four naturally sourced components: itaconic acid, arginine, pro-vitamin B5, and polysaccharides from linseed and chia seeds. Each one plays a specific, non-overlapping role in the repair process, and together they do what no single ingredient could accomplish alone.
How It Works:
What the Science Shows
Tested on bleached and chemically treated hair using Dia-Stron automated tensile testing, the same equipment used in advanced fiber research.
Clean Credentials
Every component in Restart PRO 1695 is naturally derived: a fermentation-sourced acid, an amino acid, a provitamin, and two seed extracts. No synthetic fixatives, no silicones, no conventional plex chemistry. It's stable across ionic, cationic, and non-ionic formulations, which means it works cleanly inside EVOLVh's full system without compromise.

Your Hair's Natural Rebuilder, Activated
You've heard of creatine in the context of muscles. That's because it's one of the body's most fundamental building blocks, a naturally occurring amino acid derivative that the body uses to repair and reinforce structure under stress. Your hair works the same way. And when it's been bleached, colored, heat-styled, or chemically treated, it needs the same kind of rebuild.
What It Is
The creatine in this formula is bioidentical to the creatine your skin and scalp naturally produce. That means your hair recognizes it and knows exactly what to do with it. It's not a synthetic coating or a foreign compound. It's a molecule your hair fiber is already designed to work with, delivered in concentrated form where it's needed most.
How It Works
Creatine penetrates into the hair fiber and strengthens it from the inside by forming new electrostatic bridges between the keratin proteins that give your hair its structure. When those bonds are damaged or missing from heat and chemical exposure, creatine steps in to rebuild them.
It also raises the hair's natural resistance to heat, measurably increasing the temperature threshold at which hair proteins begin to break down. That means better protection every time a flat iron or blow dryer comes near your strands.
What the Science Shows
Tested against both a vehicle control and hydrolyzed wheat protein, creatine outperformed across every damaged hair scenario:
- 64% repair of bleached Caucasian hair, vs. 11% for the control
- 48% repair of chemically relaxed Ethnic hair, matching hydrolyzed wheat protein at a lower concentration
- 33% heat protection against flat iron damage on Asian hair, where the control offered zero protection
- Effective across all hair types, including Caucasian, Ethnic, and Asian hair in clinical testing
Clean Credentials
Creatine is one of the most body-compatible ingredients in hair care. It is identical to what the body already makes, which means it carries no risk of toxicity and works in harmony with your biology. There are no synthetic additives, no harsh processing agents, and no ingredients of concern.
Just a molecule your hair already knows, doing the work it was built to do.
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.
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.
Hair-Identical Amino Acid Cleansing System
Most shampoos face an inherent tension. The surfactants that cleanse effectively tend to be the same ones that strip the hair of moisture, disrupt the scalp's natural balance, and leave strands feeling rough and depleted after washing. The solution the industry settled on was to add heavy conditioning agents after the fact, often synthetic quats, to compensate for the damage done during cleansing. AminoSensyl™ Ultra MB was built to make that compromise unnecessary.
What It Is
AminoSensyl™ Ultra MB is an amino acid-based conditioning surfactant system derived from two natural sources: valine, an essential amino acid naturally found in both hair and skin, and Brassica Napus seed oil, better known as rapeseed. That pairing produces a cationic amino lipid, a conditioning molecule that carries a gentle positive charge, which naturally attracts to the negatively charged surface of hair strands for even, thorough coverage.
How It Works
When AminoSensyl™ Ultra MB meets water and hair, it self-organizes into lamellar liquid crystals, a layered molecular structure that mimics the natural lipid layers found in healthy hair and skin. Those layers deposit evenly onto each strand during cleansing, delivering conditioning benefits at the same time as the cleanse rather than requiring a separate conditioning step. The result is hair that emerges from washing already smoother, softer, and more defined, not stripped and waiting to be repaired.
What It Delivers
- Deep moisturization through amino acid and seed oil-derived lipid technology
- Smooths and defines hair from the first wash, not after a separate conditioning treatment
- Strengthens strands with valine-derived chemistry that works in harmony with hair's natural protein structure
- Weightless conditioning that doesn't leave buildup, greasiness, or residue
- Gentle on sensitive scalps, with no synthetic quats and no harsh cationic agents
Clean Credentials
AminoSensyl™ Ultra MB carries one of the most complete clean certifications of any conditioning surfactant available. It is 100% USDA biobased, COSMOS approved, NSF/ANSI 305 certified, readily biodegradable, and non-toxic to aquatic life. Its amino acid origin means it is inherently biocompatible, derived from the same building blocks your hair is already made of.
Clean doesn't have to mean a compromise on lather, conditioning, or feel. This ingredient proves it.
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.

EVOLVh replied: Aww so happy you found our masque and thank you for including a video and photo!
I received a sample of Evolvh's Smart Curl line from a clean beauty subscription box I used to get every month. Two weeks ago, I trashed all of my non-clean products and decided to use this duo (that's been sitting under my sink) in the shower. My hair was NOTICEABLY different afterwards. For context, my hair is very very thick, there is a lot of it (1/4 pacific islander), wavy/curly/frizz-prone (1/2 irish), dry and long. Because the samples were so effective, I purchased the mask and the 8.5 oz sizes of the Smart Curl line. I've been self conscious about my natural hair for the past 10 years. The Smart curl products, and this mask/"masque" have made me confident to wear my hair natural. My hair now smells incredible, is soft and shiny, and the curls aren't frizzy at all, they're defined and wavy. I've already used up half a bottle of this mask, and will definitely be stockpiling it and the Smart curl line so if an apolcalypse happens, I will still have beautiful hair. …
