We've done the testing and the maths, and we reckon it does.
You’re getting three of our 170g soap bars, which are 20-50% bigger than the standard bars that turn into a useless puddle after a week. Plus, our soap is cold-processed and cured for four weeks so they're firm and harder-wearing. One bar should get you through a month pretty easily.
Our 85g shampoo bar isn't packed with water like that supermarket fluff, so a little goes a long way. If you use shampoo every 2-3 times per week (a healthy amount for most), that's 30-45 times across 3 months.
Keep our bars dry like we suggested above and you'll be sweet for 3 months.
