		<description>Wow. When I wrote that blog entry, it was pretty much just to be silly. I never thought I&#039;d learn so much when I posted it! :-)</description>

		<description>To elaborate on ZorkFox&#039;s comment:  dandruff is caused by a relatively harmless fungal infection of the scalp.  Selenium sulphide (apologies for the European spelling) is a generic antimicrobial agent.  The topical steroids mentioned by gopher65 will typically be not so much steroids, but inhibitors of fungal steroid biosynthesis (these would be compounds like econazole, which is also in athlete&#039;s foot powder).  Fungi use a sterol called ergosterol in much the same way that mammals use cholesterol (it regulates membrane fluidity).  Inhibition of the biosynthesis of ergosterol causes the fungi to stop growing (i.e. it has a fungistatic effect); this gives your immune system the chance to destroy them.</description>

		<description>Berkeley: the joke is that we WISH the shampoo would rid us of flakey people instead of flakes of dandruff (dead skin cells from the scalp).  No shampoo really performs this function, obviously.  :)

From: http://www.nlm.nih.gov/medlineplus/druginfo/medmaster/a682258.html
&quot;Selenium sulfide, an anti-infective agent, relieves itching and flaking of the scalp and removes the dry, scaly particles that are commonly referred to as dandruff or seborrhea. It is also used to treat tinea versicolor, a fungal infection of the skin.&quot;</description>

		<description>Head and shoulders uses selenium sulfide.  Neutrogena and similar shampoos use solubilized coal tar extract.  I don&#039;t know specifically how either chemical (or possibly chemicals in the case of Neutrogena) reduce flaking.</description>
