We typically look at mites, bugs etc first, then if none most often we have found its due to dry skin (some due to inferior product ingredients), lack of brushing into the crest and dock for removal of dander & dirt. Yes its most often lack of brushing or brushing not at all!  WE want you to brush and you can brush with our product, it will be easy and no pulling or breaking of the hair. WE also have the right brushes to assist with proper care and ease for you the horse owner . Our process will also be painless to the horse too! Brush aproxiamately 2-3 times a week for the best results, 1 x a week just to prevent and maintain. So stop the rubbing now with Manely Long Hair.
