This is an amazing thread!
I'd like to make a shampoo bar of my own once I get a couple other soaps under my belt... But I'm having trouble figuring out what oils to use. I really would like to stick to oils that I either already have, or have ordered and are on their way. What I have are coconut (which most say not to use!), canola, soy (liquid), EVOO, a little container of avocado, jojoba, and castor.
Other additives that I want to use are marshmallow root, chamomile, lemon, calendula, honey, and citric acid (with a corresponding adjustment to the lye to balance it out).
I have long blonde hair that I'd like to lighten up a bit and bring out the natural red highlights. It's also dry, a mass of tangles, easily gets static-y, a bit frizzly, and the underside can be curly while the top tends more towards waves than curls. I've already started rinsing with an acidic rinse (switching off between lemon and ACV), using less shampoo, and doing twice-weekly overnight coconut oil treatments. These have helped some with my hair (it's never been quite this curly before!), but I'd like to improve it more and get away from the harsh shampoos I've been buying at the same time.
I also have liquid rock coming out of my tap. I hate it, but there's no changing it. That's the logic behind the addition of citric acid-to act as a chelator to counteract the hard water.
Thanks for the help!
