Co-Wash with theThe Earthling Co. Conditioner Bar

Ok hear me out- 45, starting to grey and these hairs break and frizz, orherwise blond fine hair, history of being oily fast. What I want is moisturized, volumized hair that I dont have to wash everyday. This is it- despite being fine haired, using this conditioner bar as a cowash does the trick- use lots of water to get it distributed, scrub scalp with a silicone scalp brush and let sit while you do other things for a few minutes ( ie shave) and rinse well ( I use the handheld shower head to get the most pressure). This gets me great hair for 2 days then use Tap Secret dry shampoo powder to get 1-4 days. No smell. Use the shampoo bar once every 4-6 weeks. Air dry. Easiest and best hair I have had. We have very hard water for reference.
