I've noticed a definite increase in itchiness, especially after adding TTO to the shampoo itself. (I hope it's only dry skin and not combative mites objecting to the TTO and pushing back. ) I think I'll try a plain shampoo tonight without any TTO and note itching results. Last night I was not happy , trying to decide if I should get out of bed and put lotion on my back. I've been using shampoo as a body wash too for past couple of weeks and definitely have drier skin. I still think about mite 24/7. Just received a bottle of Tea Tree Special; may have ordered the wrong one, as don't see lavender as ingredient and I believe yours has that. Sodium lauryl sulfate is drying to hair but is effective against mites and fungi (didn't know that) is the second ingredient listed after water .
