I tried it because I'm trying to switch from commercial shampoos to bar shampoos, as the former contain a lot of chemicals that are harmful to the hair. I can't evaluate if it stops hair loss, because surely a shampoo alone is not enough for such a thing. But I believe that it definitely does not worsen any corresponding problem, due to its natural composition. It cleans the scalp satisfactorily and leaves a feeling of cleanliness. However, what bothers me is the complete lack of hair hydration, as if you used green soap. The hair remains stiff and dry after washing, to the point where I couldn't run my fingers through the roots. I think if the company fixes this aspect a little, it will be an excellent choice.
