What are hair building fibres?


Hair building fibres are often referred to as just hair fibres, and can be made of a number of different materials. Cotton and plant derivatives are often used as hair fibres, as they can be much cheaper to source and produce than other alternatives.


However, the best option for a completely seamless result is a fibre made from 100% natural keratin. Keratin is a protein that makes up human hair, so using the exact same material means you are guaranteed to get the most natural-looking, near invisible result.


The finely milled hair building fibres are also dyed to suit various hair colours, from the darkest black hair to the lightest blondes, greys and even white hair.


What do they do?


In simple terms, hair building fibres adhere to the hair strands to thicken and conceal thinning throughout the hair. They are a fast and hassle-free alternative to expensive and risky hair loss treatments and can easily be washed out with shampoo.


Who can use hair building fibres?


Hair building fibres can be used by almost anyone, whether just as an added thickness or as a concealment for advanced hair thinning. That being said, they cannot cover complete baldness as they do require some hair strands to cling on to.


Hair building fibres can be used by both men and women to target all types of hair loss and thinning, including male and female pattern baldness, post-partum hair loss, Telogen Effluvium and many more.


Even if you don’t suffer from hair loss, hair building fibres are ideal for added lift and thickness at the roots, evening out hairlines and even hiding extension clips! Need a bit of grip and fullness for that new hairstyle you’ve been dying to try? Fibres could be the perfect solution!


Which hair building fibre is the best?

Hair fibre texture

Not all hair building fibres are created equal! As we mentioned before, fibres made from 100% natural keratin give a far superior finish to those made from cotton, plant derivatives and other synthetic materials.


But there is more to it that that. Some of the best hair building fibres are backed by extensive research and innovations that set them apart from the rest.


For example, Nanogen’s Keratin Hair Fibres feature its unique Kinetic Strip which gives each fibre a dipolar charge (making one end positive and the other negative) to allow them to firmly bind to the natural electrostatic charges found throughout human hair. Not only that, but the dipolar charge means one end of the fibre with alway repel away from the hair strand which creates our innovative ‘fir-tree pattern’, giving added thickness and dimension not found in other brands.


It’s also imperative to find a hair binding fibre that promises a colour lock technology which guards against leaking dye and staining in light rain or sweat. Some fibres that don’t feature this technology can actually end up ‘bleeding out’ throughout the day… the last thing any fibre wearer wants!


How to use hair building fibres


Using hair building fibres is incredibly easy… and fast! There are a lot of outdated opinions that concealment products are messy and fake-looking, but truth be told we’ve come a LONG way since that hair in a can! Using fibres takes seconds and can easily be added into your morning routine, without having to sacrifice that lie in!


Follow our simple steps to getting the most from your hair building fibres:


  • STEP 1: On dry hair, lightly sprinkle the fibres onto the areas you need it, such as the hairline, bald patches or the parting. Remember, less is more!

  • STEP 2:Gently blend in with your fingers for a completely seamless look. For more coverage, gradually build up the fibres to avoid clumping and allow them to blend into the hair.

  • STEP 3:For best results and waterproof hold, spritz with a Hair Fibre Locking Spray.

And that’s it! A few hair building fibre brands also allow you to blend together a few colours to achieve your perfect shade. Simply apply the darkest colour to your hair first, then lightly tap on the lighter shade and blend together with your fingers. This enables you to add a peppering of grey or white to suit more mature hair, and even mimic highlights in dyed hair.


Using hair building fibres with other hair loss treatments


Hair building fibres are far from the only hair loss treatment on the market; a quick Google search will bring up a ton of options for those of us suffering with hair loss, so it’s no wonder many people are left feeling overwhelmed with choice.


The beauty of hair building fibres is that they can be used in conjunction with many other treatments to conceal bald spots and thinning while you wait for the treatment to take effect. Since many hair loss treatments can take up to six months to really see a difference, using fibres in the meantime is a great way to create the appearance of thicker hair. You can be safe in the knowledge that your hair fibres won’t interfere with the effects of your treatment, whether its a hair growth serum, a medical solution like minoxidil or finasteride, or even a thickening shampoo and conditioner routine.


If you are using a topical hair loss treatment, simply apply to the scalp and allow to dry before shaking on your hair building fibres. For hair transplant patients, we would recommend consulting your doctor about using fibres after treatment.


Hair building fibres side effects


It’s an often asked question whether hair building fibres have any side effects, and a valid one at that. While the side effects are incredibly few and far between, it’s important to know all the facts.


  • Ammonium chloride Some hair building fibres are formulated with ammonium chloride which is a non-organic ingredient used in a number of products as a thickening agent to help dyes stick together. Although it has been declared safe to use topically, any chemical can be hazardous if a significant amounts enter the body, causing muscle spasm, irregular breathing and irritation. We advise using a hair fibre that does not contain ammonium chloride.

  • Cotton As we’ve already mentioned, some hair building fibres are made from cotton fibres which can cause severe allergic reactions including rashes, dermatitis and respiratory problems. Those with a cotton allergy should steer clear of cotton-based hair fibres.

  • Dyes Perhaps the only side effect that is relevant across all brands of hair fibres, dyes can cause allergies like skin irritation and redness. We recommend you do a patch test on a small area of skin 24 hours before you use them to see if you react negatively - many brands offer a trial size of their hair building fibres that would be perfect for this.
