From Panier des Sens, a solid shampoo bar in Regenerating Honey, for dry hair. "This mild ultra-foaming, pH-neutral, sulphate-surfactant- and silicone-free, eco-friendly shampoo cleans, nourishes and protects dry hair right down to the tips. Light yet deliciously-sweet creamy honey that mellows almond flowers and sandalwood." $14 for 75g.
From Carol's Daughter, Wash Day Delight Water-to-Foam Shampoo with Rose Water: "Carol's Daughter Wash Day Delight micellar cleansing vegan shampoo with Rose Water transforms from a water to a gentle foam lather for a deep clean without stripping or harsh friction to help cut down time on wash day. Perfect for natural, curly, kinky and coily hair, our targeted applicator helps the liquid formula instantly flow through hair providing easy scalp access and quickly rinses clean. This sulfate free shampoo for naturally curly hair transforms from a liquid into a gentle foam lather without harsh friction and effortlessly works throughout minimizing tangles." 500 ml for $10.99 at Carol's Daughter.
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).
From Yves Rocher, shampoo bars ("generous foam and it smells really good!") in Gentle ("gently washes hair, leaving it soft and shiny"), Shine ("leaves hair shiny, soft and radiant") and Nutrition ("with infused oils nourishes and leaves hair shiny, soft and full of vitality"). $19.95 each for 60g.
A lemming for fans of Aveda Shampure: a new limited edition shampoo bar. "94% naturally derived shampoo bar gently cleanses and provides weightless, long-lasting nourishment while infusing hair with our signature calming shampure aroma." $19 for 100g, and if you buy by April 30, $5 of that goes to charity: water to provide clean water to countries in need.
