Moisturizer Answers

After 4 months of not knowing why my hair was falling out & having ultimately thinned by half. I realized it all began when I started using head & shoulders
*Warning for anyone thinking about using this* If you see one bit of change in your hair STOP or better yet find another product.
Is there a way to reverse the effects & get my thickness & length back? I read online to steam or sit in a sauna to remove the gunk stuck to the hair & pores. What should I do for shampoo & conditioner? A particular hair style, oils, vitamins that would be helpful? I don’t want to make it worse by using a bad shampoo or conditioner. I never have colored or used dryers & straighteners on my hair. It used to be down to my butt & a nice thickness (not too thick) but now it is a little below the shoulder a half the thickness (it seems like it even got a little more wavy or maybe I notice it more because there is less weight from the top of my head?). The bangs that I had grown out (I trimmed them earlier in ‘09) have broken off! The hair falls out easily but not as bad now that I stopped using H&S. My hair has almost no weight to it. It is awlful. I can not do anything about the color change but just FYI for everyone whole hair strands turned white. In four months whole strands turned white! I hate H&S.
What do you think or know about Paul mitchell ‘The conditioner’ leave in moisturizer & conditioner? I looked that up (and every other product located in the house) & found a lot of people gave this P.M. product a bad review. I am afraid to use any products now. I did use the old herbal essences S&C for a long time but they were discontinued. Please Help me!

im 16. i think the marks are from weightlifting. i know it cant go away permanently . but i just want to make it less noticeable because its really red. i tried using cocoa butter for about a month i barely see any results. & i also use moisturizer because i heard it helps but i still dont see anything happening . can any body help me out?
