PRO FORMULATION WITH DHT INGREDIENTS: Nirvasa hairfall control shampoo comprises the newest blend which your hair and scalp would love to absorb. Since it is embedded with DHT blocker ingredients- Saw Palmetto as one of the active constituents, it helps block the effects of 5-alpha-reductase, which in turn stops the conversion of t-level into DHT hormone; as a result it majorly works in controlling hair fall issues in men and women.
