Oh Ann, ....if there is such a product, the companies sales would be phenomenal! Honestly, I've tried just about all of the products out there (you know me
) and I've yet to find one that actually prevents mats. I've got lots of ideas and products on how to remove mats once they've formed, but it would be the best news to find something that did prevent them.
Where are the mats, under the legs and tummy area? If that's the case, trim the hair as short as possible...you can't really see the hair there if you keep any length of skirt, so it won't matter to cut it off.
