Jo W.I got this for my partner to help with his confidence and even I was shocked at the result. I can't believe how well the product blends and looks so natural! Great customer service and fast delivery too!
Mark S.This really is the best on the market! The colour match is spot on and how it blends in to your natural hair is brilliant. I will always buy from here until I deceive to bite the bullet and get a hair transplant
Jake B.I can't believe how good these fibres are, tried two shades before getting the bigger pot. Was so skeptical before trying this
Simon T.Recently purchased the starter bundle and I've been using the products for a few days now. As a 34 year old man with an ever increasing forehead I needed some help. Instant results and easy to use. Thanks HG Team
Robert W.Thank you very much for my item you sent out , colour is brilliant
Frequently Asked Questions.
Our fibres are made from natural cotton using our proprietary CottonWrap™ technology. Unlike keratin-based fibres, cotton fibres naturally wrap around your existing hair strands for a denser, more undetectable finish. They’re plant-based, vegan, and gentle on even the most sensitive scalps.
Application takes about 30 seconds. Shake the bottle gently over thinning areas, starting from the crown and working forward. Tap lightly to let the fibres settle, then finish with 4–6 light mists of our Locking Spray. For precision around the hairline, use our Easy Apply Fibre Pump.
No. Our cotton fibres are completely undetectable, even in bright sunlight and under close inspection. CottonWrap™ fibres blend seamlessly with your natural hair texture. Most of our 30,000+ customers tell us nobody can tell they’re using anything at all.
Yes. Once secured with our Locking Spray, Hair Guru fibres are resistant to rain, sweat, and wind. They’ll hold up through your gym session, a rainy commute, or a long day outdoors. The fibres stay in place until you wash them out with regular shampoo.
We offer 14 shades to match virtually every hair colour. Use our free AI Colour Match Scanner — just scan your hair and get your perfect shade in 10 seconds. When in doubt, go slightly darker for the most natural result.
Our standard 28g bottle lasts most people 1–2 months with daily use. For lighter touch-ups, it can last even longer. We also offer a 100g Refill Pouch for better value and a 5g Sample Size to try before you commit.
Absolutely. Our fibres are made from natural cotton with no harsh chemicals, synthetic dyes, or irritants. They’re dermatologist-friendly and safe for daily use, even on the most sensitive skin. The formula is also vegan and cruelty-free.
We offer a 30-day money-back guarantee. If you’re not completely satisfied, contact us and we’ll sort it out. We also offer free shade exchanges if your colour isn’t quite right, and free replacements for any lost packages.
