I love to make my own body, face, and hair treatments. I use baking soda as an exfoliant on my face everynight because its very easy on my skin. I use it in my hair once a week to get rid of buildup. I use applecider vinegar 2x a week on hair for ph balance. I use a small amount of olive oil for my hair 1x a week as hot oil treatment. I aslo use avacados in my hair, you can mix w olive oil if you want. I use natual sugar and honey as a body exfoliant. It makes your skin SOOOOOO soft! This one is not cheaper than the store bough ones like st ives but I do like it anyway.
These things are just cheaper and so much better for you as they don't have all the chemicals the other products do.
