VegeKeratin
A keratin grown from plants — wheat and soy amino acids, tuned to hair’s own — that leaves the Masque smooth, conditioned, and easy to comb.
VegeKeratin is a plant-built protein — a blend of wheat and soy amino acids, tuned to mirror hair’s own — used to condition, smooth and add slip, and to help hair feel stronger and more resilient.
It’s the plant-protein note of the No. 4 Hair Masque — the conditioning layer that works alongside shea’s deep moisture.
A keratin, grown from plants
Hair is mostly keratin — so this one is built, amino acid by amino acid, to speak the same language.
Hair is made largely of keratin, a protein spun from some eighteen amino acids. VegeKeratin sets out to echo that — not with animal keratin, but with amino acids drawn from wheat and soy and blended, in the ratios hair itself favours, into a plant-grown stand-in for the real thing.
To that base are added three pure amino acids of fermented-plant origin — arginine, serine and threonine — the arginine especially, nitrogen-rich and long prized in hair care. The result is vegan, gentle, and small enough in size to be genuinely useful to hair rather than merely sit on top of it.
It suits a brand like Juje. A ritual handed down through hands, reaching now for the plant-built version of an old and simple idea: give hair a little of what it is made of, and let the result feel like care.
The molecular portrait
Small, water-loving amino acids — set in the ratios that hair itself keeps.
Because these are free amino acids rather than large peptides, VegeKeratin is unusually small and water-loving — which is what lets it condition and hold moisture so lightly.
Four quiet mechanisms
Conditioning that echoes hair’s own chemistry — light, smoothing, and made to be felt.
It speaks hair’s language
Its amino acids echo the ones hair is made of, so it conditions in a way that’s compatible with hair’s own chemistry.
It binds moisture
Small, water-loving amino acids help hold moisture in the hair, for a suppler, more flexible feel.
It smooths and adds slip
A light conditioning film settles over the surface, smoothing the cuticle so hair looks shinier and combs more easily, wet or dry.
A plant-built strength you can feel
As a vegan stand-in for animal keratin, it helps hair feel stronger, softer and more resilient — and look healthier.
What the research shows
Ingredient-level context on plant proteins in hair — and carefully claimed.
Formulation science has long used proteins and amino acids as hair conditioners precisely because their make-up is so close to hair’s own — which is what makes them substantive to the fibre and useful for smoothing and softening.
Low-molecular-weight, highly hygroscopic amino acids of the kind in VegeKeratin are documented to hold water in the hair and support its flexibility and feel — the moisturising side of a plant protein.
Vegetable proteins are well characterised as film-formers that lay a light, protective layer over the hair surface, improving smoothness, shine and combability — the classic conditioning signature.
Protein actives are often sold on “strength” and “repair.” Read honestly, the evidence here supports conditioning, moisture and smoothness — how hair looks and feels — and that is the only language Juje uses.
A clear, weightless solution
Not a powder and not an oil — a light, water-based blend of amino acids that all but disappears into a formula.
What it is. VegeKeratin arrives as a clear, near-colourless solution — small amino acids already dissolved in water, ready to work. It carries no oil, and no weight of its own.
Why amino acids. Fully hydrolysed to free amino acids, it is smaller and more water-loving than a typical hydrolysed protein — which is exactly why it conditions so lightly and rinses clean.
Where it sits. In the water phase of the No. 4 Hair Masque, added gently on cool-down so the amino acids keep their character.

Hair Masque
In the No. 4 Hair Masque, VegeKeratin is the protein note — plant amino acids that condition and smooth, working alongside shea’s deep, cushioning moisture.
A division of labour. Where shea brings rich, buttery moisture, VegeKeratin brings the protein side — conditioning, slip, and a smoother, stronger feel.
Light, on purpose. Because it is small and water-based, the protein conditions without weight — the Masque stays rich from its butters, not from the protein.
Plant to the core. An animal-free keratin echo, in a formula built to be botanical — vegan, and gentle enough to reach for often.
The language we stand behind
For retail, stylists and press. VegeKeratin is a cosmetic conditioning protein — we speak to how it makes hair look and feel, never to changing its structure.
- A plant-built protein that conditions and smooths
- Helps hair feel stronger, softer and more resilient
- Adds slip and shine; eases wet and dry combing
- Binds moisture for supple, flexible-feeling hair
- A vegan alternative to animal keratin, from wheat & soy
- Repairs, rebuilds or restructures the hair
- Bond-building · fixes or seals split ends
- Strengthens the hair’s internal structure
- A keratin treatment · anti-breakage · anti-inflammatory
- Any medical or drug claim
Protein is often sold on “strength” and “repair.” On a Juje page we describe only what VegeKeratin helps hair look and feel like — conditioned, smooth, supple — never what it does to the hair’s structure.
Plant-grown, and animal-free
VegeKeratin is a small act of substitution: the conditioning idea of keratin, met without an animal. Its amino acids are drawn from wheat and soy — renewable, widely grown crops — and finished with pure amino acids of fermented-plant origin. For a brand that is botanical, cruelty-free and vegan by design, it is the natural way to bring protein to the Masque: plant-grown, and gentle on hair and conscience alike.
Asked & answered
What is VegeKeratin?+
A vegan, plant-built alternative to animal keratin — a blend of wheat and soy amino acids, tuned to mirror hair’s own, that conditions, smooths and adds slip. It’s the protein note in our No. 4 Hair Masque.
Is it actually keratin?+
No — and that’s the point. Keratin is an animal protein; VegeKeratin is a plant-derived amino-acid blend designed to give a similar conditioning feel without anything animal-derived.
Will it repair damaged hair?+
No. VegeKeratin conditions and smooths, so hair looks healthier and feels softer, stronger and easier to manage — but it doesn’t repair or rebuild the hair’s structure. Nothing cosmetic can.
Will it weigh my hair down?+
No. It’s a small, water-based amino-acid blend rather than an oil — it conditions and rinses clean, so the Masque’s richness comes from its butters, not from the protein.
