Don't sweat the small stuff.
Hair fibres, regardless of brand, are dyed to match the desired end colour. That's great,but the last thing you want, when you’re working up a sweat in the gym or caught out in the rain, is any colour leaking out of the fibres. You can be confident when using Nanogen that the colour from your fibres won't run or stain, no matter what. Nanogen fibres benefit from our clever colour lock technology which binds the colour securely to the keratin protein to stop it from bleeding out in water or sweat. Nanogen's colour lock technology also helps prevent staining of your clothes or pillow should any fibres fall onto them.
