Soapmakers

So I just ran out of my commercial shampoo, and damned if Walmart's getting another penny of my money. Shampoo recipes plz? I have oily hair and lots of it, so that needs to be accounted for in the recipe, as does the fact that my soapmaking skill level is single-scent melt-and-pour.

Thanks!

ETA: mods, can has appropriate tags?
