@27823c36 now, baby shampoo won't clean as easily or quickly but it seems okay for my twice weekly washing.   i guess there are other fancy shampoos that are also gentle on skin, but i haven't been inclined to go any more upmarket than johnson's baby shampoo.

have never tried the dandruff shampoo so no opinions on it 

 @5c2ba53d head and shoulders has been recommended as the "nuke from orbit" option, and it worked back in the 90s. 🤔
