I love this company. Shipping is always super fast, and a lot of the time they include complementary samples in my orders. The first time I tried shampoo bars my hair just wouldn't acclimate to it so I emailed them with questions. They responded with plenty of advice and I found out my water was just too hard (I lived in an old house in Utah), but once I got a shower head with a water filter my hair cleaned up right away.
Another thing I love is the pet shampoos. I have a lab so he's too big for the tub, and he hates hose showers. With the shampoo bars I can give him a bath when we go to the lake for a swim and I don't have to worry about harmful chemicals getting in the water and hurting the fish!
