I literally think about a post-apocalypse world everyday. It always motivates me to learn new skills! I defiantly am still working on my solid shampoo recipe and from time to time buy ones in stores to get inspiration. I feel like they are much more gentle on my hair than the ones in bottles, plus shampoo bottles are rarely truly recyclable. Hopefully one day I will be able to make all the skin/hair care products I use but, until then there is a lot of experimentation and trying out other products. I do hope you enjoy your calendula tea!!
