Sep 24, 2013 - I have loose curls and relatively fine hair. I found that Bigen shampoo was too heavy for me. It was hard to rinse out and left my scalp feeling oily. It defined my curls fairly well, but the scalp oiliness put me off. In addition, the chemical smell was too strong; it made my eyes sting. I think this product is ideal for someone who needs a "heavy" shampoo - i.e. someone with a dry scalp that needs conditioning or someone that tends towards frizzier curls that need definition.
