Thanks, Stilly, I pulled out the bottle and it's next to the computer now, looking at the label, which says a quantity of things. For instance:

"NO parabens, phthalates, formaldehyde, petrolatum, sulfates, mineral oils, artificial colors, or artificial fragrances."

The brand is "Derma E [trademark]" made in Simi Valley, California. "Scalp Relief Shampoo."

The label extols the virtues of a proprietary herbal blend:
Neem, burdock, bearberry, also Tea Tree oil and Menthol.

A further breakdown of ingredients, from most to least quantity.
Water. Three things I'm not going to attempt.
Glycerin. Epilobium Angustifolium Flower/Leaf/Stem Extract.
Willow Bark Extract.   Sodium Chloride (hey! even I know what THAT is).
Salicylic Acid. Menthol. Tea Tree leaf oil. Arctium Lappa root extract.
Chamomile flower extract. Uva-Ursi leaf extract.
The names are getting grandiose again so I'll stop... here.
