100% natural keratin hair fibres for men and women who want to instantly improve the appearance of their hair. Nanogen's Thickening Hair Fibres are the perfect way to add volume and thickness to your hair in just 30 seconds. Nanogen's revolutionary hair thickening fibres are made from high quality, 100% natural keratin; a fibrous protein found in hair strands. They merge perfectly with your own hair using electrostatic charge to give instant, natural and durable hair thickness which lasts all day. Choose the colour that's right for you. Nanogen Keratin Hair Thickening Fibres are available in ten natural shades that can be mixed and matched to any hair colour including greys and highlights. Use the darker colour first as a base, and then use the lighter colour fibres to touch up. Fibres are for anyone who wants to add volume and thickness to their hair. Use them to boost your roots, to create THE red-carpet style or to hide hair extension clips or a widening parting. Nanogen hair thickening fibres give an instant and natural looking result. To use: 1. Style your hair as normal. 2. Lightly sprinkle on areas of hair where thicker hair and volume is needed. Gently blend the fibres with your fingers. 3. For best results and to waterproof use our Hair Fibre Locking Spray. Good to know: less is more with fibres. Start gently and build layers of fibres until desired volume is achieved. Wash out with shampoo.
