Laxatone for hairballs?

Neely is a meticulous groomer and has somewhat frequent hairballs. I tried using Laxatone but it made her vomit a watery brown liquid so I stopped. Has anyone had the same problem and/or know of a better solution? (BTW, I do comb her regularly.) Thanks, I appreciate any tips or advice.

oil ( fish or salmon is best but olive and flax also work ) ... I like vet basis over laxatone cause it doesnt have petroleum

Thanks for the tip, I will definitely try the oil.

I've found the pastes to be quite messy and Oliver decided to not like the taste all of a sudden for whatever reason... I did pick up a container of the Pounce hairball treats cuz they were on sale AND I had a coupon (haha major deal there!) and they seem to work pretty decently... He's had a couple of hairballs since I started with these in the spring, but no more than he was producing with the messy paste stuff (plus on an occasion or two, I forgot to give him the treats after he preened for hours after monthly baths, so that was my bad)... he is short hair though... just a thought
