Avalon Organics Tea Tree Scalp Treatment Shampoo - I've seen a few different brands with Tea Tree offerings that claim to have anti-dandruff properties. In the product description for this one, it says, "This shampoo balances the scalp's delicate chemistry and gently cleanses, as restorative beta glucan helps reduce dryness and irritation." The shampoo is nice, has a pleasant scent, but I haven't found that it makes any difference for my flaking and itchiness. It's fairly inexpensive, though, which is nice.
Regenepure DR Scalp Treatment anti Hair Loss and Dandruff Shampoo topical with Ketoconazole - I found this on Amazon and was very hopeful. It's expensive at $25, and it contains Ketoconazole, which is one of the lotions that I use on my face to treat my Seborrheic dermatitis, so I was feeling optimistic about this one. And, amazingly, it says that it contains no animal by-products and, on the bottle itself, says that it is only tested on humans. Nice. Although I referred to PETA's list of companies that do and don't test on animals and couldn't find Regenepure, or their parent company, Salonceuticals, on either list. But on the Regenepure site, they say they don't test on animals, so I'm inclined to trust that. The first application of the shampoo was interesting, as there was a definite tingling feeling happening, so I figured it must really be working. Unfortunately, I didn't notice any difference at all in the flaking or itchiness. I've been using it for over a week now, and haven't noticed anything in the way of resolving this issue. The other thing that it reports to do is to help hair look and feel thicker. Haven't really noticed much of that going on either. I think I'll try using it two or three times a week, and rotating in the Avalon Organics shampoo to see if that helps.
