An ongoing topic on this thread is what to shampoo with if regular shampoo is irritating to your scalp.

Currently I'm buying from the Vermont Country Store website,
a product called Silver Savior shampoo.
The silver ingredient is something called colloidal silver.
Sadly, for those who are extremely sensitive,
this product still has laureth this and paraben that in it,
so it won't work for people who have coconut allergies, for example.

It seems to be working for me, though.
My scalp has settled down wonderfully using this product.
