Hi there! I went through the same issue. You need to use vinegar as a conditioner to close your hair follicles. Do a ratio of vinegar to water that you feel most comfortable in. Honestly, in the beginning I used to be very cautious and precise with my ratio but now I just scoop baking soda and put it directly on my scalp. Then I just put my head under water and scrub scrub scrub. Then with the vinegar I just pour it directly on my hair while my heads under water.
Its been almost 2 months since I went no-poo and my hair is definitely improving. It is much more manageable and softer. My hair is getting less oily as well. My only issue is I guess I'm not scrubbing the dead skin cells away thoroughly because I get dandruff easily, but that's just me.
Good luck, hope all goes well.
