Cleaning your showerhead will depend on how much water is used in it daily and how much soap/shampoo you use every day. It’s also important to keep your showerhead clean as well since bacteria can build up quickly in a dirty shower head and cause mildew or mold problems if not cleaned regularly enough. If you’re not sure how often you need to change your shower head, make sure you take the time to clean it at least once a month.
