Nizoral 1% Shampoo

Nizoral AD 1% shampoo is an over-the-counter shampoo which has been formulated to control and reduce dandruff. However its active ingredient is 1% ketoconazole and it is this ingredient that it is believed can decrease the rate of hair loss and improve hair thickness. Other anti-dandruff shampoos on the market where the active ingredient is 1% zinc pyrithione have been shown to have the opposite effect.
