Like true beauty, healthy hair really does come from within. But that doesn’t mean you can’t give Mother Nature a helping hand - especially when it comes to hair growth and thickness.
Hair thinning is more common than many people think.
Research shows that around 40% of women experience hair loss or thinning by midlife, with other stages such as pregnancy and menopause also increasing the risk.
Stress, nutrition, and ageing all play a role, but one factor that often gets overlooked is collagen.
Collagen is a key protein for skin, nails, and joints, but it’s also closely linked to hair growth and thickness, so knowing how to maintain your levels is key to keeping hair strong and resilient.
What Does Collagen Do for Hair?
Collagen is the most abundant protein in the body, supporting skin, bones, tendons, and connective tissues.
But it’s also essential for hair health - without it, growing strong, thick hair would be difficult.
Here are the main ways collagen and hair growth are linked:
● Supports keratin production – Collagen provides amino acids that your body uses to make keratin, the protein that forms about 95% of each hair strand.
● Improves hydration – Hair cuticles are overlapping layers of keratin that hold in moisture. When collagen levels dip, hair can become drier and more brittle.
● Boosts elasticity – Just as collagen gives skin firmness, it adds flexibility to hair, helping it bounce back and reducing the risk of snapping during brushing or styling.
● Protects against free radical damage – Collagen helps shield hair follicles from oxidative stress caused by UV rays, pollution, and poor diet.
● Adds shine – Collagen repairs cuticles for smoother strands and supports sebaceous (oil) glands, which condition hair naturally.
● Encourages thickness – While follicle size is largely genetic, collagen supports blood flow and scalp health, helping hair grow stronger and appear fuller.
Together, these functions explain why collagen decline often shows up in hair that looks thinner, weaker, or dull - and why supporting your collagen levels can make such a visible difference.
Where Do We Get Collagen From?
Our bodies produce collagen naturally, but levels decline from our mid-20s and drop more sharply with age. That’s why hair can start to feel weaker, thinner, or more brittle over time.
Supporting your body’s collagen levels can help, and there are three main ways people try to do that:
Food sources
Certain nutrients help your body make collagen.
Vitamin C, zinc, and copper are essential for this process, which is why citrus fruits, leafy greens, beans, nuts, and seeds all play a role in supporting natural collagen production.
Animal collagen
Some supplements are made from cow hides or marine fish.
While they provide amino acids, studies have shown marine and bovine collagens can contain hidden toxins and heavy metals, raising safety concerns.
They’re also linked with environmental issues, from deforestation and methane emissions to overfishing.
On top of that, the amino acid profile doesn’t precisely match human collagen, which can affect how well it works.
Vegan collagen supplements
A newer and safer option, vegan collagen uses plant-based ingredients to mimic type I human collagen and stimulate your body’s own production.
Formulas like VeCollal® go further - they are scientifically developed to identically match type I human collagen, something bovine and marine collagens simply can’t achieve.
Why Choose Vegan Collagen for Hair Growth and Thickness?
Unlike animal-derived options, vegan collagen can be designed to work in perfect alignment with the body.
Arella Collagen contains VeCollal®, a biomimetic, plant-based formula that identically matches type I human collagen.
That means your body recognises and uses it effectively to support hair growth, thickness, and resilience, while also being sustainable, cruelty-free, and suitable for all diets.
A Closer Look Inside Arella Vegan Collagen
Arella Vegan Collagen Supplement with VeCollal® is more than just collagen support.
It combines a carefully selected blend of nutrients that work together for hair health:
● VeCollal® – Plant-based collagen alternative that stimulates your body’s own collagen production.
● Vitamin C – Essential for collagen synthesis and defending cells from oxidative stress.
● Biotin – A B-vitamin clinically recognised for supporting hair growth and strength.
● Asiaticoside – From Centella Asiatica, a natural stimulator of collagen production.
● Ginseng – Promotes circulation and cell renewal, supporting thicker, stronger hair.
This combination means Arella doesn’t just top up one nutrient, but addresses several factors involved in collagen and hair growth.

Collagen Hair Growth Before and After: What the Evidence Shows
When you’re considering a supplement, it’s natural to wonder what difference it will make.
The best way to answer that is by looking at both research and lived experience.
In vitro studies on VeCollal®, the plant-based collagen in our product, show it can stimulate collagen production by up to 134%.
In practical terms, that means giving your body the building blocks it needs for stronger, healthier hair.
There’s also growing media attention about the power of vegan collagen.
We were featured in the Daily Mail, where former Love Island star Malin Andersson spoke openly about her struggles with hair trauma and how collagen support is helping her rebuild confidence.
She said: “I switched up my diet and kept on going with @arellauk as I’m in awe of their collagen … and now 6 months later my hair is BACK!!!”
Real people seeing visible results is what gives weight to the science.
Together, the research and real-world results show why collagen is linked with noticeable improvements in hair growth and thickness.
