Just wondering because I HATE my high castor oil shampoo bars on my hair with 15-20% and I do the vinegar rinse. My hair just has this greasy film and I've been using bar soaps for months now. I bought one that seems to work but I want to make one for me. Just used a mostly OO soap on my hair and it's great. Think I'll skip the castor for awhile. Anyone else notice that?
