I was talking on the phone with Sweet Cheeks (Laurie) the other day. I've been soaping for 16 years; Laurie is a certified Master Soaper, charges beaucoup bucks for her classes, wholesales to the premier Denver Brown Palace Hotel and Gaylord Spa at DIA among others. She and I both make lye-based shampoo bars. We both have fine thin hair. Personally, I didn't become a soaper only to go back to using a syndet (synthetic/detergent) shampoo. She laughed when I told her about the Syndet crowd here. She said,
"I love my shampoo bar and it sells well. My hair has so much body after shampooing with it!"
Her recipe has few oils and is easy to make:
80% olive oil + 20% castor oil.
Directions:
Zany's No Slime Castile
Shampoo Bars have been discussed many times on SMF. Take some time to search "
Shampoo Bar" to get both sides of the story before you decide which way to go. Also, be aware that it may take some time for your hair to adjust to using soap for shampoo. Doing the search will help you understand more.
