I use the tee tree “conditioner” as my “co-wash”, to wash at my scalp. Then condition all my hair with the Smooth as Silk Deeper Moisturiser, by Giovanni. I don’t use an actual shampoo. The tea tree fragrance is nice, and not too strong. It can tingle the scalp a little bit sometimes, and give a temporary cool feel, but it’s fairly mild. The larger size containers and the pump are really handy. (I found the small size annoying to get the last bit out) I find that my scalp doesn’t get itchy, even after a week of not washing - which used to always happen. My scalp also doesn’t get as greasy as it used to, because I’m not removing all the natural oils when washing my hair. I labelled my bottles with permanent marker, because the bottles look too similar, particularly as I’m short sighted.
