I am quite new to this site and new to losing my hair. I have been to the doctor and she took quite a few blood tests. On my first visit she gave me steroid injections in my scalp. What does this do? Has anyone here ever had their hair completely grow back? I am going back to the doctor again this week to discuss the blood test results. I feel like starting the visit with her by asking what exactly do I have and what can be done about it. I now have a large spot on the top of my scalp and a couple of smaller ones down low on the back of my scalp. I have been reading a lot of the postings and am worried about the side effects of some of the treatments. I have read replies to posts that discuss biopsies. Will a biopsy give me one specific name regarding the type of hair loss I have? It also seems that a lot of the postings and replies state that some of the doctors are just not helpful at all in knowing what is happening with their patients. This thing I have is frightening and depressing and I wish I had someone to hold my hand through all of this.
