It's been a fairly slow journey, but I've managed to make my shower/beauty routine very simple and natural.
Castile Soap . I am currently working on making a felted soap bar out of an old sweater. I'll let you know how that turns out!
If you are considering switching up your beauty/bath routine, let me just warn you, the baking soda and vinegar routine is the hardest to get through, because there is a period of adjustment for your hair. Don't start this if you plan to go to a salon soon, or they'll advise you to stop. It can take up to a month before the oils in your hair naturally adjust to your new cleansing routine.
All of the items above cost pennies per use, and except for the castor oil, I already keep every other item stocked up for other uses. I do not buy anything extra in order to green up my shower routine. I love that.
