Excellent product and service! I have very long, fine, straight hair and all the bars I have tried worked great for me. I have way more volume in my hair and they last longer between washes. It took me a while to learn how to wash my hair. With traditional shampoos there is nothing to learn because the chemicals are so strong that application does not matter. Two tips I have for those with long hair are: rinse long and wash the back of your head most carefully. I used to always only wash the top of my head with traditional shampoo. With beauty and the bees bars, I mostly need to focus on the back of my head. I rinse either with apple cider vinegar or clarifying rinse. For the first time in my life, I do not use conditioner. I cannot wait to get rid of all the plastic in my bathroom.
