Big head improver into fresh wort

Hi guys,I have just purchased 2x fresh wort 20ltr kits one is a dark stout the other is a qld ale,has anybody use or is anyone using a beer topper from brewcraft called bighead improver it's a natural tastless seaweed based additive that gives a creamy head with staying power I'm thinking of putting this into the worts can I do this,this is my 1st attempt with wort kits,i know i can mix co2 and nitrogen to get the head retention but would like to try this additive,I use a keg king kegging system,thanks
