Common Questions About Hair Fibres
Considering hair fibres for the first time? We've compiled answers to the most frequently asked questions to help you make an informed decision and get the best results from your hair fibre products.
What Are Hair Fibres Made From?
Hair fibres are made from either keratin (the same protein found in human hair) or natural cotton fibres. Both types are safe, effective, and designed to blend seamlessly with your natural hair.

Are Hair Fibres Safe to Use?
Yes, hair fibres are completely safe for daily use. They're non-toxic, hypoallergenic, and don't damage your existing hair or scalp. Unlike some hair loss treatments, hair fibres have no side effects and can be used by anyone, including pregnant women and those with sensitive skin.
How Long Do Hair Fibres Last?
Once applied with a hold spray, hair fibres typically last all day - through work, exercise, and social activities. They're resistant to wind and light rain. However, they will wash out completely with regular shampoo, so you'll need to reapply after each hair wash.
Will Hair Fibres Look Natural?
When applied correctly and colour-matched properly, hair fibres are virtually undetectable. They blend seamlessly with your natural hair and move naturally. Even in close-up situations, quality hair fibres like our Thickify Hair Fibres look completely authentic.
Can I Use Hair Fibres with Other Hair Products?
Yes! Hair fibres work well with your regular styling products. Apply your usual mousse, gel, or hairspray first, style your hair, and then apply the fibres as the final step. You can also use hair fibres alongside medical hair loss treatments like Minoxidil or Finasteride.
Do Hair Fibres Work on All Hair Types?
Hair fibres work on virtually all hair types - straight, wavy, curly, or coily. They're effective for both men and women and work on fine, medium, or thick hair textures. The key is having some existing hair for the fibres to bond to.
How Much Hair Do I Need for Fibres to Work?
Hair fibres work best when you have at least some existing hair in the thinning areas. They're designed to add volume and coverage to thinning hair rather than create hair where none exists. For completely bald areas, fibres may not be as effective.
Can I Exercise or Swim with Hair Fibres?
Hair fibres are sweat-resistant when sealed with a hold spray, making them suitable for light to moderate exercise. However, they're not waterproof, so swimming or heavy sweating may cause them to wash away. For active lifestyles, we recommend our Hair Guru London Hair Fibres with a strong hold spray.
How Do I Remove Hair Fibres?
Simply wash your hair with your regular shampoo. Hair fibres rinse out completely, leaving no residue. There's no special removal process required.
Can I Sleep with Hair Fibres In?
While it's possible, we don't recommend sleeping with hair fibres applied. They may transfer to your pillowcase and won't look as fresh in the morning. It's best to wash them out before bed and reapply in the morning.
What's the Difference Between Keratin and Cotton Fibres?
Keratin fibres are made from protein and typically provide a more realistic appearance with stronger bonding. Cotton fibres are plant-based, vegan-friendly, and more affordable. Both are effective - the choice depends on your preferences and budget.

How Long Does a Bottle Last?
A typical 28g bottle lasts 30-60 days with daily use, depending on the size of the area you're covering and how much product you apply. Most users find they need very little product once they master the application technique.
Can Hair Fibres Cause Hair Loss?
No, hair fibres do not cause hair loss. They simply sit on top of your existing hair and wash out completely. Unlike some hair loss treatments, fibres don't affect your hair growth cycle or damage your follicles.
Are Hair Fibres Detectable in Photos?
Quality hair fibres photograph beautifully and are undetectable in photos when applied correctly. They don't create shine or an unnatural appearance in flash photography, making them perfect for weddings, professional headshots, and special events.
What If I Choose the Wrong Colour?
Colour matching is important for natural results. If you're unsure about your shade, contact our team for personalized colour matching advice. We're happy to help you find your perfect match.
Can I Use Hair Fibres on Facial Hair?
Yes! Hair fibres work excellently on beards, mustaches, and eyebrows to fill in patchy areas and create a fuller appearance. The application technique is the same as for scalp hair.
Do I Need Special Tools to Apply Hair Fibres?
Most hair fibre bottles come with a built-in applicator. You don't need any special tools, though some users prefer applicator pumps or spray applicators for more precise application. A fibre hold spray is recommended for best results.
