was going to make the hose suggestion but after re reading your post I see you are fermenting............no clue but the molases worked for me with force carbonation

I use maltodextrine in my homemade soda to help with body. It seems to improve head retention too. I make syrup though and add carbed water to taste.

So I know that this might sound a bit back alley, but what about non toxic liquid soap? 1/2 drop per liter and I can't taste it in root beer, but the foam stays.

Ultimately you need a surfactant like yucca root extract(I couldn't find this anywhere), but that is what makes the bubbles stay not under carbonation. Think suds bucket, has no carbonation.

Try different amounts in a pint of water whisk a bit look at suds, then taste. Us the least amount possible then scale it up. If you force carb, the carbonation is there it just is letting the bubbles pop too easily.

Do you wash your glasses in a dishwasher? Certain soaps kill suds! Ask your favorite bartender to sample their glass wash and try it again.

I know a long time ago, the brewing industry used Gum Arabic to enhance foam.
Don't know the first thing about it but I know that they did it at least as an experiment.

I used glycerine and lactose in my last batch of root beer. You could float a bottle cap on it the head with no soapy taste

1/2 cup molasses will do the trick

Yucca extract & malto dextrin is the same thing. Malto = tapioca starch = made from yucca.

Definitely adds foam retention. Gum Arabic is a pricey way to add foam and needs to be done at the end and carefully so you don't make it thick. Can make a nice simple syrup with it for adding foam to whatever in the fly.
