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.
