Arrow Product details

Instant and natural looking results


Perfect for men and women looking to improve the appearance of their hair


Nanogen hair thickening fibres are made of high quality, 100% natural keratin; a fibrous protein found in hair strands. Our fibres look more natural than others e.g. rayon, nylon and cellulose, and merge with your own hair making it visibly thicker and fuller.

Available in 10 natural shades. Mix and match for highlights or a more vibrant colour.

We use colour lock technology - use with confidence - fibres will not stain.

Natural keratin fibres, dermatologically tested.


How Nanogen fibres work


Nanogen keratin fibres merge perfectly with your own hair using electrostatic charge to give instant, natural and durable hair thickness which lasts all day. Wash out with shampoo.

With kinetic technology


Kinetic charged fibres maximise the hair thickening effect. Plus they bind up to 400% stronger than others. Look for the metal strip.

How to use

1. For best results, first cleanse the hair using Nanogen Hair Growth Factor Shampoo and then either Nanogen Hair Growth Factor Conditioner or Nanogen Hair Growth Factor Mask. 2. Allow hair to dry completely, and if you use Aquamatch apply this now, before applying Nanogen Fibres. 3. Hold the jar at a slight angle and lightly shake small amounts of Nanogen Fibres evenly over the thinning area. 4. Blend the fibres gently into place using your fingertips. 5. Repeat steps 3 and 4 until you have perfect coverage, you can also blend different colours for highlights or greying hair. 6. Apply Nanogen Fibre Locking Spray to bind Nanogen Fibres even more securely and make them water resistant.

does what it says on the tin! I'm a 55 yr old woman who has always had very thick hair- as I've got older hair on top is thinning - especially around my parting ( plus going grey - so that doesn't help! - anyway - I really notice it ) although admittedly I still have lots of hair elsewhere. But sprinkling this on definitely creates volume! I used sprays before - they are also very effective - used bumble & bumble - but they tend to leave a horrible stickiness. KEY TIP. to ensure you don't lose shine - lift top layer of hair with tail comb and sprinkle underneath - and hey presto- volume but still nice and shiny ( plus you can always use a spray shine on top) Love this product - and I've tried everything!

Nanogen Fibres very pleased with the product it's on the expensive side but does work. In places my hair has gone thin, I shake this on and it clings to hair, great if you have a double crown and too many partings, or if a partings too wide. I know it will last me longer then the month, it stays in your hair till you wash it, none of it in my case was left in the bedding which I thought might happen, so I'm well pleased. October 7, 2012
Couldn't live without it. I've always been very insecure and when i noticed my hair starting to thin in my early 20's i was distraught. Refused to go out, couldn't look people in the eye, always wearing a hat. The day i found this my life changed, of course i would like to not have to use it, but i couldn't live without it. Thank you Nanogen! March 6, 2013
