I got Trader Joe's brand castille soap and wouldn't recommend it for shampoo. Dunno about the other brand though. Just watch out for
added glycerin, as it makes you hair greaser, faster. I got the one I like online, and use 1/4 cup castille soap to 1 cup water. I don't add anything else, and it works just fine.

Lonelilly, mine is unscented! Does yours smell like peppermint? I didn't care for that smell on my head.
Anyway, I love my new routine. Castille soap, and ACV rinse!
