There are many recipes out there for making your own products, so I will share mine and link you to some others.
Washing powder:I currently use - 1 cup of washing soda, 2 cups of grated sunlight soap and a tablespoon (or so) of vinegar in the rinse cycle. It goes okay.
I used to use this recipe, until I read this article. Borax is not a friend to your garden, and you don't need it, so ditch it!
In frugal circles, people swear by liquid laundry detergent like this one. I'll be honest and say that I have never made or used it, but it is definitely a cheaper alternative to the one I make.
Shampoo and Conditioner
When I was Buying Nothing New for a Year, I started using bicarb and apple vinegar to wash my hair. I did it for more than a year, having stopped only a few months ago when we had a nit invasion and I needed to buy conditioner in bulk! It is a simple and cheap way to maintain your hair and will reduce the amount of hair washing you need to do (once a week only). Check this out if you want to know more.
There are many other alternatives to traditional shampoos and conditioners. Take a look at this for a nice summary of your options, but bare in mind that these have an green priority and may not be as frugal as you'd like.
Wash your face with honey. Nothing else. Give it a try and let me know how your skin feels after a week. I like it because it is natural, simple and it works.
Maria from EcoNest has some great ideas for natural face cleansers, toners and moisturisers with varying degrees of difficulty. Mostly they are made from foods that you can find in your garden or crisper, so they are frugal and a good way to use up strays from your shopping list.
