I live in India, and have actually been using stuff from this brand for nearly twenty years! Contrary to the reviews you’ve posted, this shampoo works wonders for my hair …I have black hair, mid back, type 1B. And it’s dirt cheap at about half the price of Head and Shoulders.
It foams a lot less, but it behaves like any old shampoo out there. I suspect they’re hiding the surfactants and preservatives used, or using something that masquerades as “stabilizers”
