folliman; you only need a tiny, tiny bit. you should see very slight transfer when applying (like puppy tracks LOL)...and I mean VERY SLIGHT. once dry, it will be invisible but you will notice a slight difference in texture of the lace. slightly stiffer.
apply this SMALL amount once a month and you are good to go. there is enough product to seal 20 hair systems.
so it is economical and safe!
