To extend the life of any bar soap, including this one, the key is to minimize the time it spends sitting in water. A pool of water will slowly dissolve the soap, creating a soft, mushy layer that gets wasted. For best results, use a soap dish with drainage holes or ridges that elevate the bar, or consider a magnetic shower holder that lets the soap cling to a wall, fully exposed to air.
Between uses, place the soap in a location within your shower or bathroom that isn't directly under a dripping tap or showerhead. Allowing it to dry completely helps it maintain its firmness and thickness. This is especially practical for a multi-use soap like this one, as you'll likely be handling it more frequently for both hair and body. Proper storage ensures you get the full value from the 250-gram bar and keeps it hygienic. If you travel with it, let it air dry completely before packing it in a ventilated travel container.
