If you’re already vegan (or mostly there), there’s a good chance you’ve had this moment: you’ve got the food side sorted, you’re mindful about clothes and home products… and then you look at your shampoo and think, what’s actually in this? If that’s you, you’re in the right place.
Vegan hair care can feel hard to pin down. Some products look plant-based until you dig into the ingredients. Others say “natural” or “kind” but don’t mention animal-derived proteins. It can be hard to know what’s meaningful, what’s marketing and what’s verified.
Today, we break down what vegan hair care really means (including what vegan certification checks), the ingredients that catch people out, and how vegan hair care products still deliver real results - especially if your hair is feeling finer, drier or more fragile.
We’ll also dig into the science behind common “hero” ingredients (like argan oil, biotin and plant-based keratin), so you can choose products that match your values and your hair.
What does vegan hair care mean?
At its core, vegan hair care means a product contains no animal-derived ingredients and has not been tested on animals. But that definition only scratches the surface.
A genuinely vegan hair care product must consider:
- Where each ingredient comes from
- How it’s processed
- Whether animal by-products are used at any stage
- How the finished formula interacts with the scalp and hair fibre
This matters because hair care has traditionally relied heavily on animal-derived proteins. Ingredients like keratin, collagen, silk amino acids and lanolin were long considered gold standards for strength and shine. But they all come (or used to come) from animals.
Modern vegan hair care takes a different approach. Instead of relying on animal proteins, it focuses on plant-based alternatives and advanced cosmetic science to achieve the same (and often better) results, without compromise.
What does it mean to be vegan certified?
This is where things really start to matter. Plenty of hair care products describe themselves as “vegan-friendly”, “botanical” or “plant-based”. But without certification, those labels can be vague and sometimes misleading.
For anyone navigating vegan hair care in the UK, certification from bodies such as The Vegan Society offers reassurance. Certification means a product is independently assessed to meet strict criteria. And it’s not just what’s on the label. Vegan certification also reinforces a commitment to vegan, cruelty-free hair care, ensuring animal welfare is never compromised.
So, what makes a haircare product vegan?
A vegan-certified hair care product must:
- Contain no animal-derived ingredients, including less obvious ones like keratin, collagen or silk proteins
- Be cruelty-free, with no animal testing at any stage of development
- Use supply chains that meet verified vegan standards, rather than relying on assumptions
- Avoid animal-based processing aids during manufacturing (which can otherwise be hidden from ingredient lists)
From a customer’s point of view, certification removes uncertainty. You don’t have to cross-reference ingredient names or second-guess where something came from. The checks have already been done.
How can hair products be vegan?
This is usually the point where people pause, and fairly so. Hair is made of keratin, so it’s natural to wonder how hair care can work without animal-derived keratin at all.
The key is understanding what hair actually needs to stay strong and healthy.
Hair doesn’t require animal protein specifically. What it responds to are:
- Amino acids: the small molecules that make up proteins, including keratin
- Lipids: fatty substances that protect the cuticle and reduce moisture loss
- Moisture balance: enough hydration to keep hair flexible, but not overloaded
- Cuticle support: ingredients that help the outer layer of the hair lie flat and intact
Historically, keratin (sourced from animal hair, feathers or horns) was used because it resembled the keratin found in human hair. However, these proteins are relatively large molecules. They tend to sit on the surface of the hair, creating a temporary coating that can feel strengthening, but may lead to stiffness or buildup over time.
Modern cosmetic science has moved on.
Today, formulations replicate the function of keratin without using animals. They break plant proteins down into smaller, “bio-compatible” components using processes like hydrolysis and fermentation.
Just like the “real” thing, plant-based ingredients deliver amino acids supporting hair’s natural protein structure, smooth the cuticle, and improve elasticity and tensile strength - essentially helping hair bend rather than snap.
Are vegan hair care products better for your hair?
While there’s no universal rule, there are clear patterns.
The best vegan hair care products use fewer harsh surfactants and chemicals, rely on naturally derived ingredients and avoid heavy animal proteins that sit on hair. They also often focus on scalp health as well as hair appearance.
From a scientific perspective, scalp health is foundational. Hair grows from the scalp, and anything that disrupts its balance (irritation, dryness, inflammation) can affect growth, shedding and overall hair quality.
Because vegan formulas are often sulphate-free, they’re well suited to:
- Fine or thinning hair
- Hair prone to breakage
- Sensitive or reactive scalps
- Hair going through postpartum or menopausal changes
- Hair worn with extensions
Environmentally, vegan and cruelty-free products also tend to have a lower ecological footprint, especially when paired with responsible sourcing and sustainable packaging.
Because the molecules are smaller and more targeted, they’re often:
- Better tolerated by sensitive scalps
- Less likely to cause heaviness or stiffness
- More suitable for regular use
- Safer for fine hair and luxury Virgin hair extensions
In other words, vegan hair care doesn’t mean doing less for your hair. It means doing it more intelligently.
The Phoenix Crown approach to vegan hair care
For the Phoenix Crown hair care range, our aim wasn’t simply to create a “vegan” product, but to create a supportive, confidence-restoring routine.
Our formulas are:
- Vegan certified
- Cruelty-free
- Sulphate-free
- Naturally derived
- Safe for natural hair and luxury Virgin hair extensions
At the heart of the range are three key ingredients: biotin, argan oil, and plant-based keratin - each chosen for a specific role in supporting hair health. Here’s a deeper look at each.
Is argan oil vegan friendly?
Yes, argan oil is vegan. The only times it wouldn’t be, are if it’s mixed with animal products such as honey or beeswax, or if animals (such as goats, on some traditional farms) are used in the production process.
Argan oil is derived from the kernels of the argan tree and has a long history of use in hair and skin care. From a biochemical point of view, it’s effective because it closely mirrors the natural lipid composition of healthy hair.
Argan oil is famed for its antioxidant and anti-inflammatory properties. It’s rich in Oleic and linoleic acids, Vitamin E and natural antioxidants.
These compounds help:
- Smooth the cuticle
- Reduce friction between hair strands
- Improve shine and softness
- Protect against environmental damage
Crucially, vegan argan oil for hair nourishes without heaviness, making it ideal for fine hair and extensions. In a well-formulated vegan argan oil shampoo or conditioner, it works alongside gentle surfactants and other strengthening ingredients to support hair from the inside out.

Is there such a thing as vegan biotin?
This one’s a bit more complicated. But yes, biotin itself is vegan.
Biotin (vitamin B7) is essential for keratin production in the body and plays a role in maintaining healthy hair, skin and nails. In hair care formulations, biotin is produced synthetically or via plant-based fermentation, making it fully compatible with vegan standards.
Topically, biotin helps:
- Improve hair strength
- Support elasticity
- Reduce breakage
- Promote a healthier scalp environment
So why might people think biotin isn’t vegan?
The confusion usually comes from supplements. Some biotin supplements use animal-derived fillers or processing aids. In vegan-certified hair care, this isn’t the case - the biotin used is independently verified as vegan.
Does vegan keratin exist?
Just like biotin, there’s often confusion about the vegan status of keratin.
So, does vegan keratin actually exist?
No. At least, not in its original biological form.
Keratin itself is an animal protein. But what does exist is plant-based keratin - a blend of amino acids and proteins designed to mimic keratin’s structure and behaviour.
Can keratin come from plants?
Through cosmetic science, yes. At least functionally!
Vegan keratin is created using:
- Hydrolysed plant proteins
- Amino acid complexes
- Fermentation techniques
This process replicates keratin’s amazing ability to:
- Bind to damaged areas of the hair
- Smooth the cuticle, leading to increased shine
- Improve strength and elasticity
- Reduce breakage and improve manageability
Because these molecules are often smaller than traditional keratin, they’re less likely to sit heavily on the hair or cause buildup. For hair that’s fine, menopausal, postpartum, or worn with extensions, this balance is essential.
So, is keratin in shampoo always vegan?
No, keratin itself isn’t automatically vegan.
When an ingredient list simply says “keratin”, it doesn’t tell you where that keratin comes from or how it’s been produced. In many conventional hair products, keratin is still animal-derived unless stated otherwise.
This is where vegan certification is essential.
Any vegan-certified shampoo should be able to prove that:
- Any keratin-like ingredients are not animal-derived
- Alternatives are chosen for performance as well as ethics, not simply to meet a label requirement
- Claims are backed by ingredient sourcing and verification, not just wording
Rather than asking consumers to decode ingredient lists, certification provides clarity. You know the keratin-related ingredients are there to support hair strength and smoothness, without conflicting with vegan values.
Final thoughts: is vegan better for your hair?
Vegan hair care isn’t about trends or perfection. It’s about intentional formulation.
When done well, vegan hair care supports scalp health, respects fragile hair, avoids harshness and aligns beauty with ethics.
Phoenix Crown’s vegan hair care range was created to do exactly this - combining biotin, argan oil and plant-based keratin (as well as other superhero ingredients) to support strength, softness and confidence, without compromise.
Whether you’re navigating change or simply want hair care that feels considered and kind, vegan hair care is a powerful place to start.
