I started using this product for the past 2 months and I can only find the 1lt size at a JHB Industrial distributor (Jumbo) because that's how much I love the product. I wish the large size was available at clicks but I can also understand why it is not. The 1lt lasts me a year at around R230. The product gives my hair strength immediately after rinsing out and minimizes shedding too! I would buy this product even if it was sold in 5lt bucket!
