The perfect partner to Nanogen’s Keratin Hair Fibres; This natural Hair Fibre Locking Spray is specially formulated to hold Nanogen’s Keratin Hair Fibres in place and waterproof your hair all day, even under water.



While hair fibres have their own innate staying power, you can get a more confident hold in blustery outdoor conditions by using a few sprays of this ultra-strong Hair Fibre Locking Spray. Add ‘double sprays’ for serious water resistance (see below for test results). Hair Fibre Locking Spray is suitable for Minoxidil users and is designed specifically to be used alongside our Hair Fibres. With translucent shine enhancers and UV filters, this hardworking spray even helps protects colour from sun damage and delivers an unrivalled natural looking finish with every use. The tried and tested spray system has been carefully selected for its wide and gentle spray application so as not to dislodge your perfect fibre pattern when applying.


Go about your day in full confidence!

Whether you are training at the gym or you get caught out in the rain, Hair Fibre Locking Spray locks our natural Keratin Hair Fibres in place all day long – even under water*. This light hold spray keeps your hair looking healthy and fuller while providing a completely natural shine, meaning you can go about your day in complete confidence.

*In clinical tests, 90% of Fibres remained in place after 5 minutes immersion in water.

Backed by Science

Our Hair Fibre Locking Spray uses patented waterproofing styling polymers, translucent shine enhancers and colour protecting UV filters that shield each hair fibre from colour damage.

This ensures your hair stays looking thick and healthy all day.

Nanogen Hair Fibre Locking Spray is especially formulated not to affect penetration of Minoxidil or any other topical treatment.
