We don't have the STYLE refills anymore and have switched all STYLE into infinitely recycleable aluminum tubes.
BUT THE MOST IMPORTANT THING TO TELL YOU IS... Please do not mix STYLE with water in the bottle. Water is the one ingredient that will foster bacterial growth in literally all cosmetic products. The preservatives in cosmetic products are meant to keep the amount of water naturally in the products from growing bacteria, but if additional water is introduced to a formulation (not just ours, but ANY formulation), that water will break the anti-bacterial protections built into the formulation. Water is the one ingredient to NOT add to products, either directly by adding pure water, or indirectly by adding products with a significant concentration of water in their formulation.
That said, we recognize that some users may want to thin their C+K products out before applying. Great news: C+K products are made to mix! SUPERWATER, TONIK, or SETSPRAY are great ways to thin STYLE before applying. We suggest mixing together in your hands right before you apply them, instead of mixing in the bottle ahead of time and allowing to sit. That way the water is introduced to the product for moments, not potentially for months.
