No poo scalp/dandruff troubles

Hello all, I am in need of some no poo advice.


I started no poo two months ago. My problem is that I am getting terrible dandruff. This is accompanied by a very very itchy scalp, and my hair feels like it has a lot of buildup in it. I think some of the blame lies in the fact that I live in Texas right now, and have very hard water. As of right now I don't really have much of a way around this.

My current routine is this:
comb through my scalp and hair with a comb
rinse with 1/2 water, 1/2 white vinegar, making sure to get all of my scalp, and sometimes if I'm extra itchy I comb through my scalp and hair while applying the water/vinegar mix
I think make a baking soda paste and massage that into my hair and scalp
I let it sit for a few minutes, then rinse
then I use acv/water on my hair, usually just on the longer part of my hair

I've tried a few other things to get rid of the dandruff and buildup. I cut back on the amount of baking soda I was using, and right now I'm using as little as possible. I tried first some brown sugar and honey, and then just brown sugar to scrub my scalp. Last weekend I put some warm evoo and tea tree oil all over my head and scalp, and left it on over night. This helped the itching for a few days, but by Tuesday I was itching again, and it made my hair super greasy and gross. I also tried using Dr Bonner's peppermint soap on my hair, but that didn't do much of anything.

I've read through the no poo posts in the memories, and I searched the community and read any of the no poo posts that showed up. I tried anything that I thought applied to my situation. I'm to the point now where I'm so uncomfortable, and the white chunks are so noticeable in my hair that I'm afraid I'm going to have to go back to shampoo. The dandruff never goes away, when I washed my hair today, I got out and brushed it, and there were white chunk all over. Is all of this just because my water is so hard? I also tried both rain water and boiling my water, but neither of those helped.

Any help or suggestions would be greatly appreciated.

Thank you!
