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

Please read the enclosed leaflet carefully before 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.

Absolutely amazing! Before buying this product, I was looking into Toppik. I read a lot of forums etc and found out that Toppik had a lot of cons like itching etc. Toppik is far cheaper than Nanogen but trust me, Nanogen is far better in terms of quality and use. I spend about 30 quid on nanogen fibre and the spray which is a lot of money when you can buy a cheaper one. But I do not regret spending that money at all. I put it on the thinning areas and it takes max 30 secs for it to look amazing. You will be surprised how good you will feel about yourself. You will spend the first day looking at your hair in the mirror!! It doesnt run through your face or neck when you sweat or when it rains. It only comes off when you wash your hair with shampoo. I would defo recommend this product. April 24, 2013
Give you impression of having your hair back You can really notice that it covers white parts were you can see your scalp, at the end of the day when you remove it its shocking as it seems even clearer after being all day with a perfect coverage. I really recomenden for a temporaly solution and depending on boldness state you are in. January 21, 2014
