I've used shampoo bars before. I currently use one that I have been using for years with excellent results. One time I decided to try Burt's Bees shampoo bar, and I was greatly disappointed. It made my hair thick and greasy. It didn't wash out well. It was too smelly and didn't work well at all. It didn't lather. The scent was way too strong and made my hair smell horrible. If you have hard water, stay away from this product. If you have a water softener, perhaps it'll work better for you than it did me. Performance As stated above, it didn't work. Didn't wash out. Made my hair thick, heavy, greasy. It weighed down my hair. Felt like it hadn't washed out although it didn't lather well at all anyway, so it was hard to tell. Not a lot of lather; wasn't too soapy. Scent I'm chemically sensitive. Scent was too strong for me. Gave me a headache. I didn't like the combination of scents in this product. It wasn't what I expected from a company that supposedly makes natural stuff.
