I have a severe fibrotic,burning,contractive scalp muscle which causes a 
domino affect of burning contractive muscles and systemic ciruculatory issues. 
I 
have chroinc latent lyme that has caused this. I'd like to integrate DMSO/CS 
spray to the scalp. I purchased  70%DMSO from Jacob Labs. I was told its 
without 
toxic by-products that feed store brands carry. It smelled horribly and stung 
when I applied it at  25% dilution. What would be an effective but less 
causitc strength? Is this brand the safest to use? Can CS alone be as 
effective? 
Does it do anything to hair color? In 4 years I have turned totally gray due to 
the constant agony of this disease. Is DMSO a chemical solvent?
