Thin hair prior to surgery - scarry thin now HELP :-(

OK girls, I started with thinner, fine hair and it didn't start falling out until about 5 months out but I lost a lot and it continued to fall out until about 13 months out. I have to pull my hair back in a clip everyday because it so fine and flyaway that it's horrible. I can see new growth in my bang area and the back of my neck but it's hard to see the top of your head. I'd like to hear from others who started with thinner hair and see how they are doing and how long it's taking to fill back in. Two girls I work with had the surgery about the same time and their hair looks great but they had thick hair to begin with. I do take Centrum chewable twice a day and a special Hair vitamin I ordered off HSN twice a day. The hair I have left seems very dry and a totally different texture than before. I know I don't drink enough water and am wondering if that is making matters worse. HELP!!!!

morning ... are you getting enough protein? the hair thinning that late out sounds as tho you are having a protein deficiency...I had thin hair and lost a lot but it's now healthy and shiney - I stopped losing hair somewhere around the 6 month mark... maybe you should get a blood test and have your surgeon check your protein levels! hope other than that you're doing well... Happy New Year! Linda
