Neutrogena T/Gel: best overall
T/Gel uses 0.5% coal tar extract (equivalent to 2% crude coal tar by the historical standard), which is the concentration used in the majority of clinical trials for OTC scalp psoriasis treatment. The formulation reduces epidermal cell turnover that causes the rapid buildup of scale characteristic of psoriasis.
MG217 Psoriasis Shampoo: runner-up
MG217 contains 3% coal tar, which makes it more appropriate for moderate to severe scalp psoriasis where T/Gel's lower concentration provides insufficient relief. The higher concentration means stronger odor and more potential for hair staining, but faster results on stubborn scaling. A reasonable step-up if T/Gel does not produce adequate improvement after six weeks.
What matters most
Active ingredient concentration
Coal tar concentrations in OTC shampoos range from 0.5% to 5%. Higher is not always better: start with 0.5% and escalate only if results are insufficient after six weeks of consistent use.
Use frequency
Some formulations are designed for daily use; others are for two or three times per week. Overuse of high-concentration formulas can dry the scalp or irritate sensitive skin. Follow label directions.
Hair color compatibility
Coal tar can temporarily stain light-colored hair, particularly platinum blonde or white. Users with light hair should do a small patch test on an inconspicuous area before full application. Using a color-safe conditioner after each treatment reduces staining risk.
