I realised most of my basic health routine was useless to detrimental: - Soap: it disrupt the skin microbiome. Only useful for hand washing and to clean private parts / the bottom. Even then use high quality soap like Marseille soap or Aleppo soap. Note: Also as mentioned in the comments if you avoid soap / deodorant you *will* probably need to shower two times a day even without doing physical activities. Three time…
I have had luck opting for gentler shampoos and not using them every wash, but I wouldn’t speak for anyone else. There is large variance in peoples’ bodies.
