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.

Amino Acid Surfactants

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.

WaveMax™

Natural Definition for Waves and Curls
Most curl products deliver hold through synthetic polymers that stiffen, flake, or collapse in humidity. They force hair into a shape rather than working with it. WaveMax™ works differently: plant-derived, humidity-resistant, and built to enhance the curl pattern your hair already has.

What It Is
A 100% plant-based technology derived from flaxseed and chia, two of nature's most polysaccharide-rich seeds. Those long-chain polysaccharides have a natural bioadhesive affinity for the hair fiber, meaning they bind directly to the strand and interact with its structure rather than coating the outside. No synthetic polymers. No silicones.

How It Works
WaveMax™ bonds to keratin proteins through hydrogen bonding, the same molecular attraction that holds your hair's natural structure together. That interaction smooths the cuticle, encourages the curl or wave to form cleanly, and locks definition against humidity over time. It works with the language your hair already speaks.

What the Science Shows
WaveMax™ was clinically tested for both curl definition and frizz control, measured at multiple time points, including immediately after use and again after 24 hours of humidity exposure:

- 42% more curl definition after 24 hours vs. placebo, outperforming both benchmark competitors
- 25% frizz reduction immediately after use vs. placebo
- 73% frizz reduction after 24 hours of humidity exposure vs. placebo
- Visible cuticle improvement confirmed under Scanning Electron Microscopy, showing measurably smoother strand surfaces vs. untreated hair

Clean Credentials
WaveMax™ is derived entirely from linseed and chia seed extracts. It contains no synthetic polymers, no silicones, and no ingredients of concern. Its water-based formula is fully compatible with clean beauty standards, and its plant-based origin means it biodegrades naturally without leaving a trace in the environment.

Your curls. Nature's tools. Nothing in between.
