I read in a book that washing your hair weekly with baking soda takes all the build-up from hair products and such out of your hair. You just add about a half a palm full to your shampoo for the night and wash your hair as usual. I tried this and it made my hair VERY foamy while washing it but VERY soft the next day!
Since you can get a box of baking soda for around $.50, it keeps you from spending high prices on those clarifying shampoos and it's multi-purpose!

This is SO CHEAP and it cleanses even my oily hair and leaves it soft and silky! Follow with mixture of 1 tablespoon apple cider vinegar OR lemon juice per 1 cup water, then rinse. Beautiful!
I use baking soda on my hair about once a month to get rid of build up. The small box of soda I keep in the shower kept getting wet and the soda would clump up.
