i'm allergic to nuts as well and have thinning hair. i eat all the other seeds and coconut is fine. are you losing hair or is it just thinning all over? i have thinning hair with balding......its been rapid.
you could start with the Wormwood /black walnut hull/cloves, i've done it a few times but not sure how effective it is. what has helped me actually see parasites in the toilet has been doing Liver Flushes and diet (eating lots of leafy green vegetables, organic, more alkaline). still trying to get rid of liver flukes and others.
keep fighting, i know what you are going through and am still battling myself. we will win this.
