There’s differences in hair types and scalps and according to my experience it’s simply best to try the different hair soaps out. Only then can you really judge if one really fits your type of hair or not.
These soaps each weigh 35 grams and should last approx. 2 weeks – assuming that one washes one’s hair every second day.
Details about ingredients and other specifics of these three hair soaps can be found here:
Compostable, untreated paper
3 x minimum 35 g
9 to 10 (alkaline)
