Out of curiosity, were you mixing the BS and ACV together? Or were you washing with BS, rinsing it out, then ACV, and rinsing again? If you were mixing them, that was the problem. You should NEVER mix the two together. And you should not scrub your head at all with the BS?ACV rince. You can very gently massage your scalp. But absolutely not vigorously scrubbing.
If you were doing it correctly, and still finding white stuff, I'll bet your house you have hard water. Baking Soda is a salt. Hard water has a ton of undissolved minerals in it. Because there is already so much in the water, the BS wont dissolve well. This will cause it to build up in your hair as a white powder. Sometimes it can look like dandruff, but less itchy.
If you can, Dreadlockshampoo.com sell the best soaps for locks. It is designed to work in hard and soft water. I'd really recommend you try it out.
Welcome. The neglect method will feel so much more rewarding. I did mine with TnR, and I wish I had gone completely natural. How are you washing?
