Guys I am onto something here and need more of you to try it, I'm saying that all of this is caused by low oxygen levels this cascades to high dht and then permanent hairloss. Now this is an open account of what's helping, warts and all.
Update my scalp no longer itches hardly at all, seb derm has basically vanished.
My theory - any factor which causes poor oxygen flow to the scalp, in my case and probably many others, I believe I have 2 main causes of this;
The first being incorrect breathing and not using the diaphragm (this is caused by poor digestion), I can not stress this enough your stomach should expand on breathing in and you should feel your diaphragm press down, this pressurises your body and removes trapped gas especially if you keep your diaphragm down and continue breathing in. I'm not talking about light burps here I'm talking the dwarves dug too deep, balrog from the deep fuckers! Release some of this and see how much better your scalp feels, also things like neck/jaw cracks are related to this (arthritis as well but that's a theory for another forum), Trapped gas is soooo underrated and I think causes many immune issues along with my next point.
The second thing in my case is candida, which we all know and love as flem/mucous, this makes it's way into sinuses, air passages and our natural reaction is to tense up muscles where it is present (I didn't realise I was doing this until they started to relax) this causes our air passages to not relax and we do not draw breath into our lungs because valves like our epiglottis are permanently tense covering our windpipe,
How I am fixing this, use a high quality expensive tooth paste, I have an electric toothbrush with a small head on it, I literally use the brush to clean all my mouth and throat not just the teeth, I was amazed at how much stringy mucous I have gotten out from the back of my throat and how much better I feel! Then use listerine after.
Really I understand how all this sounds abit off the wall crazy but just try it for a few weeks and if it helps pay it forward and make sure to comment, I'm certain low O2 is the cause of hairloss and the high dht is just the byproduct of this.
