@myriamdo78 I don't shampoo or condition my hair.
I've been doing this for the past 6 years, and I have great healthy hair with no odor.
Shampoo and conditioner are lies. There are some exceptions to this, tho.
So, trial and error, give it a go for a month and only rinse your hair with water with the same scrubbing motion. Then, wash your hand with soap and do it again. You will feel uncomfortable for the first 2 weeks, but eventually, your hair will balance out.
