It's not what you think!
This is one I just can't get on board with. It's a line of thought that if you don't use shampoo and conditioner your scalp will stop producing as much oil over time(think of the olden days). Apparently, commercial shampoo strips your hair and gets your ph out of balance. Eventually it will get where you can wash your hair with plain water. Until it gets to that point, baking soda can be used to clean the scalp. Apple cider vinegar can be used to condition and shine the hair up.
I tried it. Too much work. My hair is not even that long. I would have had to make parts all over my head to get the baking soda worked in over the entire scalp. The ACV stinks. But I will give it some credit. It shined my daughter's hair up nicely. However, I don't find the work and small benefits worth it.
Soooo, I'm sticking with my shampoo and conditioner. However, I'm using Desert Essence Organics that I got from my local health food store. It claims that it's free of parabens, Sodium Lauryl/laureth sulfates, phtalates, artificial fragrances and colors, silicones, EDTA, glycol or petroleum based products. It also says it's wheat and gluten free. I don't know why that matters but I'm going with it.
I think that's a good compromise.
