Why do I feel ‘slick’ or ‘slimy’ in the shower?

If you’re not used to soft water, it’s not uncommon to leap into a shower and lather up and suddenly feel slimy, silky, or very slick. That slimy feeling comes from the glycerin in soap itself. Soft water is exponentially more effective than hard water for dissolving substances. When you’re used to using a certain amount of soap in a hard water shower, when you use the same amount of soap in soft water, you’ll be swimming in suds. You’re using the same amount of soap, but now that soap is up to 50-75 percent more effective.
