The Philip B. Anti-Flake Relief Shampoo comes in several sizes but the most standard is the 7.4oz bottle for (breathe) $35. It is meant to "heal and soothe dry, oily and flaky scalps". Here's the thing with a lot of these types of products (note T-gel complaint above), a lot of them are meant for oily scalps, not dry scalps. My scalp and hair for that matter, rarely get oily, but they can get flaky, tight and the skin can hurt as if it's pulled too tightly. When getting rid of the flakes is key, I also don't want to dry it out further as that will exacerbate the problem.
I've used this several times over the last few weeks and I really enjoy it. It smells horrible, but the scent does not cling to my hair like T-gel. Honestly, that's worth it to me. It does also work and I don't need to use it very often for it to do the job. If you can afford to spend $35 and you have dandruff or a temperamental scalp, I'd give this one a shot.
It's available at spacenk, dermstore and several other e-tailers. Around here, the only chain retail store it's carried in is Blue Mercury.
