Shampoo bars are a natural alternative to those heavy, harsh chemical laden liquid things you find in the grocery store. They are definitely something that you have to try, to see if this is right for you. I was resistant for some time, until several of my customers repeatedly asked for these. I did some research, tried out some other soap makers shampoo bars and was SOLD! I had to make my own! I formulate my bars with Jojoba oil, coconut oil, castor oil, palm oil and olive oil. I've also added Silk Peptides to the bars to help with conditioning. Do try to use these bars without using a conditioner. Conditioners just coat the hair shaft, trapping their ickies on the hair and it really does you no favors.
