Another option for a solid shampoo: L'Occitane's new bars. Three options: Purifying Freshness (blue, for normal to oily hair, with peppermint, thyme, grapefruit, mint, lavender and cedar); Gentle and Balance (lavender, with lemon, orange, rosemary, chamomile and lavender); and Intensive Repair (peach, for brittle and damaged hair, with angelica, ylang ylang, sweet orange, lavender and geranium). They do not seem to be in the US (yet?), in the UK they are £10 each for 60g (so half the price of the Yves Rocher products).
