This month, supply chain issues have become more critical. One of the detergents used in the shampoo is out of stock due to manufacturing problems. Not expected to be available again until Spring 2022. 25/30ml pots are also out of stock, next delivery expected 'at some point' in December. We are working on interim solutions whilst reformulating the shampoo. It's not a quick or easy job, so some shampoos will become temporarily unavailable. Please bear with us during these very challenging times.
