Well I was wonder if there is a period of time that if your doesnt grow back in a certain amount of time , will it ever grow back? How long do you have a spot before you know its not goimg to grow back ? I have the same one spot since about april . I can say It has grown larger since I first noticed it , But I have had a few steroid injections some hair regrowth from the first set but only in the middle of the spot so I went back to get another set of injections . I just wish that my hair would make up it's mind already . I hate playing this waiting game .
