    I know that hair on the outside of the body is dead (or so I've been led to believe) so does that mean that all them different shampoos out there for thin hair/weak hair/damaged hair/etc. are a load of crap. If your hair is dead can a shampoo really do anything?

    Your hair is composed of protein and that protein will tend to be coated in natural oils. It's not alive in that it does not produce any metabolism, but it can still be chemically modified in various ways or just coated in stuff. In many cases, you're just talking about replacing oil lost due to cleaning. But you can also add various protein bits and pieces that will structurally reinforce your hair strands as well. So it's not crap really, though the effectiveness of these products does tend to be rather exaggerated by implication in the adverts.

    Some nice general info:

    yes very true, your hair is made up of dead keratin (protein). you can to certain extent increase the volume of your hair by expanding it, using substances that trap water inside your hair shaft - moisturising it. many hair loss treatments will promise to thicken your hair and all they do is only to expand it. this strategy works as long as you are using them. once you stop your hair goes back to its original thickness. but this little hair conditioning trick keeps customers satisfied, seeing immediate results of their hair regrowth therapy.
