Depends what country you live in! In the UK T/Sal has been renamed T/Gel. What you need is a shampoo that contains SALYCILIC ACID. In the UK, T/Gel which used to contain coal tar, now contains salycilic acid and T/Sal has been discontiuned. In some countries T/Sal is still available. The name of the shampoo is not important - just make sure it contains salycilic acid because it is this that exfoiliates the scalp and aids absorption of Nizoral.
