Fine Solutions Cleansing Shampoo ($12.50 for 10.1 ounces) contains not only irritating TEA-lauryl sulfate as its main detergent cleansing agent, but also has a higher-than-usual amount of peppermint oil, neither of which will stimulate healthy hair growth (though they could cause scalp irritation). This shampoo is not recommended for any hair type.
