This week while pinteresting I stumbled upon an article on a blog about how to wash hair more naturally without shampoo and conditioner. Then I found, with a little research, that this isn't entirely unheard of. Here are the basics:
For shampoo use baking soda with water about 1 Tsp of baking soda per cup of water (adjust more or less depending on how dry your scalp is) in a squirt bottle.
For conditioner use a solution of vinegar and water (about 2 Tsp per cup of water) in a spray bottle.
Apply the baking soda mixture to the roots of your hair, massage and let sit while you shower. Rinse thoroughly. Then spray the length of your hair with the vinegar and water solution. Rinse thoroughly.
Surprisingly your hair doesn't smell like vinegar what-so-ever after you're done.
There are several benefits of using this method. One, it's super cheap. It also is much more environmentally friendly. Also, one your scalp gets used to it, your hair needs to be washed much less frequently. This is because when you use regular shampoo it strips your hair of all it's oils and then your scalp over produces oil to make up for it. However, when you use this method, the baking soda removes dirt but leaves essential oils so your hair doesn't get oily as fast because your scalp is not overcompensating.
One down aside is it doesn't leave your hair smelling nice like shampoos do. It doesn't smell like anything actually. But you can add scents with things like coconut oil if you desire.
