Hair Thickening Keratin Fibres - Medium Brown 15G (1 Month Supply)
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.
