Let’s go back to the basics! (pun intended).
Check out this simple DIY clarifier that features the star ingredient--baking soda. And remember, you should always follow up with an acidic rinse after you do a basic rinse to re-close the cuticle, apple cider vinegar is usually used for this purpose. You can clarify as often as you see fit, some curlies even replace their shampoo with baking soda. Just make sure you pay attention to your hair's reaction to the mix and dilute as necessary.
Baking soda is known for its ability to degrease stoves and to scrub off grime practically anywhere in your home, but it has also gotten its fair share of fame in the natural hair community. According to the United Nations Environment Programme, baking soda has a high pH of 9, which means it is a basic solution.
pH simply refers to the concentration of hydrogen ions within a substance. A low pH means there is a high concentration of hydrogen ions within the substance and a high pH means there is a high concentration of hydroxide ions. A substance with a low pH is called an acid, such as lemon juice, and a substance with a high pH is called a base, such as baking soda. When a basic solution is applied to the hair the cuticles open allowing the products to be released and absorbed more easily.
Because baking soda has this effect on the hair it is a great clarifier that will give your curls a great pick me up. Most clarifying shampoos contain harsh sulfates that dry out hair beyond belief, so baking soda is a great alternative.
