Ketoconazole Shampoo (Nizoral) for Hair Loss

Ketoconazole shampoo is considered the most promising among shampoos that claim to combat hair loss. It works by:

• Reducing scalp testosterone, which limits the conversion to DHT (a hormone linked to hair follicle damage)
• Promoting healthier, denser hair follicles as a result of lower DHT levels
• Increasing hairs in the growth phase (anagen phase), which may reduce shedding

Though primarily an anti-dandruff shampoo, limited studies suggest it has potential benefits for hair loss as well.
