We recently installed grey water in our house that irrigate our garden fruit trees. We have been using soap nut for laundry and Dr. Bronner’s Pure-Castile Soap for shower soap and shampoo (I also tried Alaffia shampoo). The shampoo option is very annoying because the mixture leave my hair very oily. I am looking for some recommendation for grey water safe shampoo choices that wouldn't be so oily. I read that regular shampoo is diluted enough that it can used for grey water irrigation as long as it doesn't contain the chemical below. Has anyone used regular shampoo with their grey water irrigation before? Also if you have a recommendation for a biogradeable shampoo that is good for normal/oil hair, please let me know.
