Hair loss due to anemia? scalp infection? HELP!?

When I was around 16 I noticed hair loss. Before then I had thick healthy hair. Around the age 18 my hair began to become noticeably thinner around the top of my head where my part is. I went to the Dr. and found out that I had anemia. I took about 2 bottles of the perscribed iron pills over the years. I have not been routinely sticking to taking iron vitamins and have not been back to the Dr. for bloodwork to see if Iam still anemic. My hair is still thinning and its taking its toll on my self esteem. I do not have health insurance or adequate income to be going to the Dr. as much as I should be going for this issue. I'm 24 yrs old now with hair that is thinning more and more all over I feel as if im destined to become bald and unhappy and I'm giving up hope. Is there hope for me? I also notice that I do have dandruff and sometimes get lil red itchy bumps on my scalp that scab (probably due to scratching) if I skip a day without washing my hair. Could this be due to a scalp infection? should I use Nizoral shampoo? will Nizoral shampoo help regrow my hair? other than the routine ';see a dr'; advice can anyone offer me any advice on this issue? Does anemia really cause this much hair loss? is anyone going through what I'm going through? HELP!Hair loss due to anemia? scalp infection? HELP!?
