Ok... so, I'm the founder of Kula Cloth... but let me add that I was a TRUE SKEPTIC about these shampoo bars. My sister Mare was the one who spearheaded this project. In case you haven't seen me... I have A LOT OF HAIR. I mean, we sometimes refer to it as 'the mane'. So, I very hesitantly agreed to add a shampoo bar to our Hiker Trash Apothecary line... that was last November... and I've been using the shampoo and conditioner bars EXCLUSIVELY since then. The shampoo bar lasted me and and my husband about 4 months (for one bar!!) and my hair has never been softer or more manageable. I LOVE LOVE LOVE the scent and so does my husband. My hair feels wonderful and I actually look forward to washing it. I used to go through BOTTLES of expensive conditioner to detangle my hair, and I've only used about 1/4 of a bar of conditioner in the past 4 months. It's really remarkable, and I'm so impressed and really glad we added the shampoo bar and conditioner bar to the line up. I will definitely never use anything else and I highly recommend that other folks give it a try!
