S. Boulardii probiotic for hairballs in IBD cat

I've heard several folks comment on the success they've had with their cats with diarrhea when using the S. Boulardii strain of probiotics but has anyone used it for hairballs? I currently use Provobial and am curious if I should add S. Boulardii as well. Any input is appreciated.

Probiotics will have no effect on hairballs, I believe. They work by balancing the essential gut bacteria.

Well my thought was probiotics (a different strain such as S. Boulardii) = healthier gut = less inflamation = easier for hairballs to pass....but i was wondering if anyone had some thoughts or experience with this.....

S. Boulardii is used to treat candida overgrowth in the gut for humans.  I don't think it would help with hairballs.  Perhaps frequent brushing, increasing wet food (if not already on a wet food diet), reducing grains, and perhaps a daily dose of canned pumpkin in wet food would help with hairballs.

He is brushed daily, fed only a limited ingredient wet food and he hates pumpkin. Since I added SEB + digestive Enzymes + EYL + probiotics + vet's best hairball remedy, he is MUCH better so I think all of those have contributed to the passing of the hairballs. I was just wondering if I should add S Boulardii to the mix
