Does the dove oil care shampoo reduces hair fall and can you also suggest a good shampoo tht reduce hairfall n actually works?

Hair loss shampoos: There are no shampoos that reduce hair loss. There were some articles about a very small contribution of ketoconazole shampoo to decreasing androgenetic alopecia because it has a small anti-androgenic effect, but not sufficient to make any difference. Hair loss needs a diagnosis first, then there are various treatments for different conditions causing it. Please see your dermatologist.
