A tip from the Hair Doctor, Pros and Cons

Baking Soda Rinse

Many women with natural hair believe that you should use a baking soda rinse as part of their hair care regiment.
Pro:
Although Baking Soda will strip away foreign particles and debris from the hair, and perhaps even product residue,
Con
Baking soda has a pH that will cause the hair and scalp to dehydrate and become dry and brittle, and does not actually clean the hair, because it is not a shampoo. 

Alternative
The Hair Dr. recommends that instead of using baking soda; use a clarifying shampoo that is the pH of the hair and scalp, which are 4.5 to 5.5. By doing so, you will gently clarify the hair, putting it at a pure natural state, without the dehydrating effects of baking soda.
