A customer complained that my water based, free leave in spray conditioner didn’t have enough slip for her very curly hair. She has tight curls that tangle. What ingredients have the highest slip? I use water, biokelp and marshmallow in my leave in. I have access to ceteryl and btms for conditioning. I had originally wanted to formulate something very simple that lightly coats hair, giving it shine, not necessarily a traditional leave in. Essentially something that isn’t already on the market.
