I would not do a baking soda wash and acv rinse daily. It's just too much for the hair to handle. I do an ACV rinse once every 2-3 weeks at the most.
Are you CG?
What are you using to cleanse?
Condition rinse out?
Condition leave in?
Maybe check your products labels again. You may have something that is building up and that's why you're hair looks so good after the baking soda/acv rinse.
I follow Struttswife's info.
Apple Cider Vinegar Rinse
There is some debate on whether or not an apple cider vinegar (ACV) rinse alone can clarify the hair; however, it is helpful to bring the hair back into balance after an alkaline solution has come into contact with the hair and will shut the cuticle back down. Repeated use of ACV rinses can be drying, so limit use to once per month at most:
1 tablespoon apple cider vinegar
1 cup warm water
Pour the mixture over the hair after cleansing (do not rinse out), then condition as usual. Any lingering smell will dissipate as the hair dries.
Baking Soda Clarification
With some silicone-based products, clarification must be done to remove the product that builds up over time on the hair shaft. Rather than resort to sulfate-based shampoos to remove this build-up, which can damage and dry the hair, a baking soda cleanse is preferable:
1 tablespoon baking soda
3 tablespoons curly-friendly conditioner
Apply mixture to the scalp and massage firmly, then continue to massage the mixture down the hair shaft to the ends. Work into hair well. Rinse thoroughly with warm water and follow immediately with an apple cider vinegar rinse.
Note: you must follow any baking soda cleanse with an apple cider vinegar rinse. Baking soda is alkalineómeaning it will raise your cuticle and open up your hair shaft. The apple cider vinegar is acidic and will close your cuticle back down. If you don't follow the cleanse with an ACV rinse, you'll be leaving your hair shaft open and setting yourself up for more frizz than you'd probably like.
