Neutrogena T-Gel was a very strong anti-dandruff / anti-psoriasis shampoo. It was available in original and extra strength. It was known as a "tar" shampoo, and some people swore by it to control stubborn dandruff/scalp psoriasis problems.
It vanished from stores in 2023. Why?
A class action lawsuit was filed,
claiming T-Gel contained benzene, known to be a carcinogen. Benzene was not listed among the ingredients.
Rather than modify T-Gel, Neutrogena simply decided to discontinue it. They still have a shampoo called T-Sal, which uses completely different ingredients, but is also aimed at dandruff and psoriasis. Some people alternated between T-Gel and T-Sal in order to control their problem, and are very upset that the T-Gel portion is now gone.
The lawsuit says that "benzene can cause side effects including vomiting, stomach irritation, dizziness, sleepiness, convulsions, irregular heartbeat, tissue injury, bone marrow damage, decrease in red blood cells, anemia, irregular menstrual cycles, low fertility and excess bleeding", in addition to cancer.
