So many good ideas here. I prefer to drink my waterhot now. I am not a big fan of ice.
I only wash my hair once a week. I use regular ivory soap, but have been thinking of trying trad tallow soap.
For toothpaste I have been using one from Redmond's that is clay and xylitol based. Also Huberman just did a podcast on dental care where swishing with salt water is recommended.
Something I discovered recently is that castor oil makes a great antiperspirant. You need to source organic, cold pressed, hexane free, in a glass bottle castor oil and have it on hand, for it has many uses. I also put it in my eyes for dry eyes. And it does what no eyedrop was capable of.
