No. Under normal use, Boost N Blenddoes not stain. The fibres and colours are water soluble. If you follow the directions for applying Boost N Blend you will not get it on your clothes. But if you do, just flick, pat or blow it off. If you get any on your skin around your hair line, just wipe it off with a tissue. However it is good advice to always be careful with Boost N Blendas you would with any coloured hair product. Protect yourself and your bathroom surfaces.
