How long does it take to repair a dog’s hair follicles?

The time needed to repair a dog’s hair follicles depends on the extent of damage and the repair effect. With mild follicle inflammation, consistent medication and a light, bland diet can cure the dog in one to two weeks; with severe inflammation, treatment may take about a month. Owners should not feed too much greasy food or items with many additives or seasonings, to prevent folliculitis.
