What is the best shampoo for dry scalp?

The best shampoo for a dry scalp is one that will moisturize the skin and not just the hair, but for stubborn flakes, a shampoo with salicylic acid or coal tar as the active ingredient is preferred. Popular brands of dandruff shampoos include Neutrogena T-Gel, Head and Shoulders and Selsun Blue.

A dry, flaking scalp can be caused by several different conditions, and each scalp responds the best to a different kind of shampoo. Dry flakes that look like a light snowfall are most likely caused by regular dry scalp, but thicker flakes that are yellowish or ooze and bleed can be a sign of scalp psoriasis, which may need to be treated with prescription-strength shampoos.
