Started the no-poo journey...

I fell into doing this by accident. A few weeks ago I started using a new 'natural' shampoo by Liz Earle. I bought it because it had good reviews. It left my hair looking full of stringy, greasy rat-tails. Looked gross. I later read that this is because it's an SLS free shampoo, and my hair was used to harsh cleansers and there would be a transitional phase while it adjusted. I looked lovely at my work's Christmas party, I must say. Greasilocks on the dance floor. But I persevered for a week with it looking greasy and me getting more paranoid every day until a friend suggested trying bicarb and apple cider vinegar. Long story to short, I've not used shampoo since 8th December, but I wash with water in the shower daily and I've used bicarb (baking soda) to wash with followed with a rinse of ACV. I currently do this every 3-4-5 days. I'm experimenting. It still looks kinda greasy, but it feels so much better. I'm going to try and keep this up to see if it starts looking any better. Don't want to give up and go back to shampoo so soon. The Christmas holidays gives me some time to try it out.

One thing I was wondering, is it ok to use the bicarb alone? Would this make my hair look less greasy, or would it make it really dry or even be bad for it? I was wondering if I should just be using the ACV on the ends? Also, is it ok to use this method more often, or should I stick to every 3-4-5 days? The water only method in between doesn't seem to be doing anything, but maybe it's still in the transitional phase?

Oh yes, because you don't know me, a few details - I'm in my early 30s from the UK. I have long, mostly straight, strawberry blonde hair. Prior to this I shampooed my hair daily.

Thanks and nice to 'meet' everyone :)
