This is a product/concealer I used to use before I began wearing....it`s an aerosol spray...it`s pretty good..now whether this would be more practical than sprinkling dry powders on I have no idea...it might still stain lace and be a waste of money...but the way this is applied is you comb the hair so it`s standing up and you just very lightly spray this on from a distance in an upward motion.. not aimed at the bottom of the hair shafts but upwards towards the tips [therefore in the case of a lace system it would be `away`from the base] I guess it might have the same staining-effect on lace though if you applied it too heavily....maybe other wearers have tried this or a similar product ? http://www.maneuk.com/
