Sunsilk is a hair care brand owned by Unilever, a British-Dutch consumer goods company. While Unilever has manufacturing facilities in several countries around the world, it’s possible that the Sunsilk Smooth & Manageable Shampoo you are referring to is made in Thailand and also available in Bangladesh. However, it’s worth noting that the exact country of manufacture may vary depending on the specific product batch. Regardless of where it’s made, this shampoo is designed to provide smoothness and manageability to frizzy hair, and it comes in a 300 ml bottle.
