After saunas, pools, rollercoasters, and even a wind tunnel - Kyle takes Hair Guru London fibres back to where it all started: the gym.
For most guys, the real question isn’t about skydiving or rollercoasters — it’s about sweat.
Can hair fibres actually handle a full workout?
Kyle decided to prove it once and for all with the final test in the Kyle vs Hair Fibres series.
“If they can survive this, I’ll never worry about training days again,” Kyle said before hitting the weights.
The Gym Challenge
Armed with the Hair Guru London fibre kit - pump applicator and Locking Spray - Kyle applied his fibres before his workout.
The plan: push through an intense hour of squats, sprints, and bench press in a hot gym and check if the fibres stayed in place under real sweat and movement.
The cameras followed every rep, every drop of sweat, and the final reveal.

Kyle takes Hair Guru London fibres into a wind tunnel to see if they can survive a simulated freefall.
After conquering the sauna, pool, and rollercoaster, there was only one test left - pure wind power.
So Kyle stepped into an indoor skydiving chamber, where air blasts at over 120 miles per hour, to see if Hair Guru London fibres could really hold up.
“If this doesn’t move them, nothing will,” he said, grinning under his helmet.
The Skydiving Test
Before entering the wind tunnel, Kyle applied his usual Hair Guru London fibre routine - pump applicator, perfect blend, and a strong finish with our Locking Spray.
Once inside, the instructor cranked the fans to full speed, sending Kyle soaring in mid-air while cameras caught every second.
The test was simple:
Could the fibres stay locked in when blasted by wind powerful enough to lift a human?

If hair fibres were ever going to fail, this was the test.
After smashing the sauna and pool challenges, Kyle wanted something that would really push it.
So he went to a theme park, jumped on one of the fastest rollercoasters – and put Hair Guru London fibres through the ultimate wind and speed test.
“If they fly off, they’re gone forever,” Kyle laughed as he tightened his seatbelt.
The Rollercoaster Test
Before the ride, Kyle applied Hair Guru London fibres using our precision pump and finished with Locking Spray for maximum hold.
The goal: find out if the fibres could survive high-speed wind, drops, and pure chaos.
The ride hit over 70mph - sharp turns, loops, full headwind.
By the time he got off, his hair had been through what most products would call disaster conditions.

Hair Guru London fibres — proof that confidence shouldn’t stop when the ride starts.
We put our fibres through the ultimate sweat test - and Kyle was the brave volunteer.
Most guys wonder the same thing when they first try hair fibres: what happens when you sweat?
To find out, Kyle from our “Kyle vs Hair Fibres” series took it to the extreme - locking in his style, then stepping straight into a 90-degree sauna.
“If they can survive this, they can survive anything,” Kyle said before heading in.
The Sauna Test
After applying Hair Guru London fibres with our applicator and locking spray, Kyle spent ten minutes in full heat and steam - no shortcuts.
The cameras captured every moment, from the first drop of sweat to the post-sauna mirror check.
The Result
Zero movement. Our cotton-based Hair Guru London fibres stayed completely undetectable - proof that even under intense heat, they hold like natural hair.
“I genuinely thought they’d melt off,” Kyle admitted. “But they didn’t move - still looked bang-on after.”

Spoiler: He lost. Badly.
In part two of our Kyle vs Hair Fibres series, things got competitive.
After surviving the sauna test, Kyle was convinced nothing could beat Hair Guru London fibres - until one of his mates bet him £100 they’d wash straight off in the pool.
“If they survive this, I’ll never doubt you again,” his mate laughed.
Kyle just grinned. “You’re on.”
The Pool Test
Freshly applied with our precision pump applicator and sealed using Hair Guru London Locking Spray, Kyle jumped straight into the deep end.
No gentle paddling - full dives.
The Result
Not a single patch moved.
The fibres stayed completely locked in — no streaks, no clumps, no fading. Just thicker, natural-looking hair exactly as before.
“You owe me a hundred quid,” Kyle joked as his mate inspected his hair up close.
“How is that even possible?”

Jamie here - founder of Hair Guru London. I wanted to personally share a few exciting updates as we continue to grow, refine, and improve based on the feedback we hear directly from you.
Let’s start with shipping. We’ve just introduced free UK delivery on all orders over £50 - something a lot of you have been asking for. On top of that, we’re working on a new, lower-cost option for those who don’t want to pay premium courier rates. It won’t be delivered quite as quick, but it will be far more affordable. More on that soon.
We’re also gearing up to launch two brand-new products. One of them has been developed specifically to help regular customers save money long-term - while keeping your hair looking its absolute best. Watch this space.
Now onto something we know has caused a bit of frustration - stock levels. Since Robbie Williams started using our fibres, things have been flying off the shelves faster than expected. If you’ve recently found your shade out of stock, I’m truly sorry - we hear you.
To get ahead of this, we’re now taking on additional warehouses and increasing stock levels to make sure we can meet demand better going forward. We’re grateful for your patience and loyalty while we scale to meet it.
It’s also been amazing to see Hair Guru products trusted by so many big names. Alongside Robbie, David Lauren (son of Ralph Lauren) used our fibres during his Wimbledon appearance - and there’s another global icon set to join the list this autumn. We’ll reveal who when the time’s right.
Finally, we’ve just secured our Ireland base to support expansion into Europe. You’ll start to see Hair Guru available across parts of the EU via Amazon and our website later this year.
Thanks again for being part of this journey. Every step forward we take is rooted in your feedback - and we’re only just getting started.
Big love,
Jamie Shepherd
Founder, Hair Guru London

When it comes to hair thickening products, choosing the right type of fibres can make a significant difference in achieving a natural, long-lasting look. Traditionally, keratin fibres have been the go-to option for many. However, recent advancements have shown that cotton fibres can offer several benefits over their keratin counterparts. Here’s why cotton fibres are better than keratin fibres for hair thickening.
1. Natural Appearance
Cotton Fibres: Cotton fibres blend seamlessly with natural hair due to their soft and lightweight nature. This results in a more natural appearance that mimics the texture and look of real hair. The lightness of cotton fibres ensures that they don’t weigh down your hair, maintaining a natural flow and movement.
Keratin Fibres: Keratin fibres, while effective, can sometimes appear bulky and less natural. They are heavier, which can lead to a less natural movement and potentially give away the fact that fibres are being used.
2. Adhesion and Durability
Cotton Fibres: Cotton fibres have excellent adhesion properties, allowing them to cling effectively to the existing hair and scalp. This makes them more durable throughout the day, even in challenging conditions like wind or sweat. Cotton fibres are less likely to clump together, ensuring even coverage and a smoother finish.
Keratin Fibres: Keratin fibres tend to clump more easily, which can lead to uneven application and an unnatural appearance. Their heavier nature means they are more prone to falling out in windy or sweaty conditions.
3. Comfort and Breathability
Cotton Fibres: Cotton is a breathable material, which means it allows for better airflow to the scalp. This can reduce the likelihood of scalp irritation and make wearing the fibres more comfortable, especially for extended periods.
Keratin Fibres: Keratin fibres can trap heat and moisture against the scalp, potentially leading to discomfort or irritation. The heavier nature of keratin can also contribute to a feeling of heaviness on the scalp.
4. Hypoallergenic Properties
Cotton Fibres: Cotton is naturally hypoallergenic, making it a better choice for individuals with sensitive skin or scalp conditions. It reduces the risk of allergic reactions and irritation, which is crucial for anyone using hair thickening products regularly.
Keratin Fibres: Keratin fibres can sometimes cause allergic reactions or irritation, especially for those with sensitive skin or scalp issues. This makes them less suitable for daily use for some individuals.
5. Environmental Impact
Cotton Fibres: Cotton is a more sustainable and eco-friendly material. It is biodegradable and has a lower environmental impact compared to synthetic materials. By choosing cotton fibres, consumers can contribute to reducing their carbon footprint and supporting more sustainable practices.
Keratin Fibres: Keratin fibres are often derived from animal products and can involve more intensive processing. This not only raises ethical concerns but also increases the environmental impact of their production.
Conclusion
In summary, cotton fibres offer several advantages over keratin fibres for hair thickening. They provide a more natural appearance, better adhesion and durability, superior comfort and breathability, hypoallergenic properties, and a more sustainable choice. For those looking to enhance their hair’s volume and coverage, cotton fibres present an excellent alternative that addresses many of the drawbacks associated with keratin fibres. With these benefits in mind, it's clear why more people are making the switch to cotton fibres for their hair thickening needs.
