Source — Nizoral Shampoo For Hair Loss Benefits. What Is Nizoral Shampoo and How Does It Work for Hair Loss? Nizoral shampoo contains ketoconazole (an antifungal)as its active ingredient. It first hit pharmacy shelves to tackle dandruff and seborrheic dermatitis (the flaky)itchy scalp stuff. But somewhere along the way, dermatologists started noticing something else, and patients using it were reporting thicker hair. Here's the mechanism people tend to miss. Most people use the 2% version, which is available over the counter. Ketoconazole is generally described as reducing shedding and improving hair calibre, while minoxidil remains the stronger option for regrowth.
Nizoral Shampoo Hair Growth: What the Research Says The comparisons that get quoted most set a 2% ketoconazole shampoo against a placebo in men with androgenetic alopecia, and report an increase in hair diameter and density over roughly six months. The anti-inflammatory action is the part that matters most when ketoconazole is added to minoxidil. A palmful is way too much.
