1) For conditioner - I just buy white distilled vinegar at the supermarket and put it in my hair? How much? Straight out of the bottle?
2) For shampoo - just the liquid castile soap (Dr. Bronner's) and tea tree oil? How much of each? Can I make a lot and fill a shampoo bottle with it? Or will it go bad?
1. yes to the first part of the question. Straight out of the bottle and enough to wet your hair through.
2.Dr. Bronner's liquid castile soap can be purchased with the tea tree oil already in it. There are other Dr. Bronner's soaps with other natural ingredients, for instance, lavender, just in case you want to stink nice, lol. No I don't work for the Dr. Bronner's company, it's just a great product. The product I'm recommending for your hair will also, wash your body, clothes, floors, dishes, and anything else you feel like cleaning. Anymore questions feel free to ask.
I forgot, buy a larger bottle of vinegar and pour it of into a smaller bottle for use in the bathroom, a definite money saver.
