There is no injection to make hair grow. Based on the way your dog's skin looks to me, I would be concerned about severe allergies or a hormone issue like Cushings or Hypothyroidism causing the hair loss. Fungal or yeast overgrowth is usually an issue secondary to something else like allergies or low thyroid gland production. Make sure your vet has tested BamBam for low thyroid at a minimum. If the hair loss is caused by hypothyroidism or Cushings disease the hair is not going to grow back on its own without treatment. If these endocrine issues are not going on in BamBam, and the skin infection has been adequately treated, then the hair should grow back with time. Some hair follicles take weeks/months to start producing hair again, so it takes time. Hope that helps!
