    How do you find out the iron content of hair?
    I'm trying to do a science fair experiment on what type of hair color has the best iron content. Problem is that I don't know what tools to use and chemicals I would need to to carry this experiment out. So if anyone knows how to find out the iron content of hair PLEASE let me know ASAP.

    To carry out that procedure you would need some sort of detector such as a magnet, but you would need to use A LOT of hair. A big clump, when homogenized, will be attracted to a magnetic pull, and by this you can judge the Fe content (Similar to the way an etch-a-sketch works, as you draw pictures with Fe shavings... )

    Okay, I work with VERY strong magnets-the hair would have to be VERY seriously covered with iron-rusted almost, before it would be attracted to the magnet!

    You need to freeze the sample, then grind it in a mortar and pestle, then break the proteins down with a very strong acid, then dissovlve the mix into a specific volume(I forget how to do this) then you need to perform a Titration progressively adding a reagent until the mix changes colour, this indicates how much of the elemental iron is contained within your original sample.
