I don't mind pinning. I'd rather do that be exposed to questionable chemicals.
I have an autoimmune disorder and one of the explanations for this haywiring of the immune system is this bombardment of chemicals .It mostly strikes women. Is it any wonder? Think about everything we use -- hair products, perfume, cleaning products, hair dye, nail polish. I could go on forever.
I'm just choosing NOT to subject my family or myself to anymore than necessary. Even if it's not related, it's still the best choice for us.
