My dreadlocks will be 4 weeks old tomorrow and I'm free forming. I use the baking soda and acv mix once a week and I separated for the first time today. I had to wash with head and shoulders yesterday for the itching I was experiencing. My question is, is this dryness normal? I was wondering if it was the baking soda and acv mixture that is drying my scalp out. What should I do?
